153-607: Al ( اَلْ ) means "the", and Ḥajar ( حَجَر ) means "stone" or "rock". So al-Ḥajar ( اَلْحَجَر ) is named as "the stone" or "the rock". The Hajar Mountains extend for 700 kilometres (430 miles) through the UAE and Oman. They are located on the north-east corner of the Arabian Plate , reaching from the Musandam Peninsula through to the east coast of Oman . The range is about 100 km (62 mi) wide, with Jabal Shams being

306-571: A National Youth Council , which is represented in the UAE cabinet by the Minister of Youth. The UAE legislative body is the Federal National Council which convenes nationwide elections every four years. The FNC consists of 40 members drawn from all the emirates. Each emirate is allocated specific seats to ensure full representation. Half are appointed by the rulers of the constituent emirates, and

459-565: A subspecies of Wadi Kharrar rock gecko ( Pristurus gallagheri ) are found only in Oman while Musandam leaf-toed gecko ( Asaccus caudivolvulus ), Gallagher's leaf-toed gecko ( Asaccus gallagheri ), Oman rock gecko ( Pristurus celerrimus ), Jayakar lizard ( Omanosaura jayakari ) and Oman blue-tailed lizard ( Omanosaura cyanura ) are found only in the Hajar. The endangered Arabian leopard ( Panthera pardus nimr ) had been recorded here, particularly in

612-684: A 13,000-foot-deep (4,000-metre) bore hole taking a year to drill and turning out dry, at the tremendous cost at the time of £1 million. The British set up a development office that helped in some small developments in the emirates. The seven sheikhs of the emirates then decided to form a council to coordinate matters between them and took over the development office. In 1952, they formed the Trucial States Council, and appointed Adi Al Bitar , Dubai's Sheikh Rashid bin Saeed Al Maktoum 's legal advisor, as secretary general and legal advisor to

765-525: A 24-hour curfew, and suspending all Emirates passenger flights. This resulted in a major economic downturn, which eventually led to the merger of more than 50% of the UAE's federal agencies . On 29 August 2020, the UAE established normal diplomatic relations with Israel and with the help of the United States , they signed the Abraham Accords with Bahrain . On 9 February 2021, the UAE achieved

918-909: A 40-member consultative body appointed by the seven rulers. The UAE joined the Arab League on 6 December 1971 and the United Nations on 9 December. It was a founding member of the Gulf Cooperation Council in May 1981, with Abu Dhabi hosting the first GCC summit . The UAE supported military operations by the US and other coalition states engaged in the war against the Taliban in Afghanistan (2001) and Saddam Hussein in Ba'athist Iraq (2003) as well as operations supporting

1071-470: A SW-dipping subduction zone. The two culminations are separated by the Semail Gap. This is a prominent linear structure, trending NNE—SSW. However, it is still debated as to what this structure is. Different geologists claim that it is a left-lateral (sinistral) strike-slip fault , a normal fault , a lateral ramp, a monocline due to a blind thrust , or a fault with multiple phases of deformation. There

1224-526: A broader aridification trend. The EMCI ended 18 million years ago, giving way to the Middle Miocene Warm Interval (MMWI), the warmest part of which was the MMCO that began 16 million years ago. As the world transitioned into the MMCO, carbon dioxide concentrations varied between 300 and 500 ppm. Global annual mean surface temperature during the MMCO was about 18.4 °C. MMCO warmth was driven by

1377-519: A clade of large terrestrial predatory crocodyliformes distantly related to modern crocodilians, from which they likely diverged over 180 million years ago, are known from the Miocene of South America. The last Desmostylians thrived during this period before becoming the only extinct marine mammal order. The pinnipeds , which appeared near the end of the Oligocene, became more aquatic. A prominent genus

1530-463: A conservation program on Sir Bani Yas Island initiated by Sheikh Zayed bin Sultan Al Nahyan in the 1970s, resulting in the survival of, for example, Arabian Oryx , Arabian camel , and leopards . Coastal fish and mammals consist mainly of mackerel , perch , and tuna , as well as sharks and whales. The climate of the UAE is subtropical-arid with hot summers and warm winters. The climate

1683-561: A cooler, drier climate. C 4 grasses, which are able to assimilate carbon dioxide and water more efficiently than C 3 grasses, expanded to become ecologically significant near the end of the Miocene between 6 and 7 million years ago, although they did not expand northward during the Late Miocene. The expansion of grasslands and radiations among terrestrial herbivores correlates to fluctuations in CO 2 . One study, however, has attributed

1836-623: A democracy. According to the 2023 V-Dem Democracy indices , the United Arab Emirates is the third least electoral democratic country in the Middle East . The United Arab Emirates comprises seven emirates. The Emirate of Dubai is the most populous emirate with 35.6% of the UAE population. The Emirate of Abu Dhabi has 31.2%, meaning that over two-thirds of the UAE population lives in either Abu Dhabi or Dubai. Abu Dhabi has an area of 67,340 square kilometres (26,000 square miles), which

1989-505: A dialogue partner of the Shanghai Cooperation Organisation . Human rights organisations consider the UAE substandard on human rights, ranking only 6.06 in the human freedom index , citing reports of government critics being imprisoned and tortured, families harassed by the state security apparatus, and cases of forced disappearances . Individual rights such as the freedoms of assembly , association , expression , and

2142-412: A federation of seven hereditary tribal monarchy -styled political units called Sheikhdoms . It is governed by a Federal Supreme Council made up of the ruling Sheikhs of Abu Dhabi , Ajman , Fujairah , Sharjah , Dubai , Ras Al Khaimah , and Umm Al Quwain . All responsibilities not granted to the federal government are reserved to the individual emirate. A percentage of revenues from each emirate

2295-473: A good analogue for future warmer climates caused by anthropogenic global warming , with this being especially true of the global climate during the Middle Miocene Climatic Optimum (MMCO), because the last time carbon dioxide levels were comparable to projected future atmospheric carbon dioxide levels resulting from anthropogenic climate change was during the MMCO. The Ross Sea margin of

2448-435: A good model for a "living fossil". Eucalyptus fossil leaves occur in the Miocene of New Zealand , where the genus is not native today, but have been introduced from Australia . Both marine and continental fauna were fairly modern, although marine mammals were less numerous. Only in isolated South America and Australia did widely divergent fauna exist. In Eurasia, genus richness shifted southward to lower latitudes from

2601-572: A historic milestone when its probe, named Hope , successfully reached Mars 's orbit. The UAE became the first country in the Arab world to reach Mars, the fifth country to successfully reach Mars, and the second country, after an Indian probe , to orbit Mars on its maiden attempt. On 14 May 2022, Sheikh Mohamed bin Zayed Al Nahyan was elected as the UAE's new president after the death of Sheikh Khalifa bin Zayed Al Nahyan . The United Arab Emirates

2754-444: A humid southeastern wind known as Sharqi (i.e. "Easterner") makes the coastal region especially unpleasant. The average annual rainfall in the coastal area is less than 120 mm (4.7 in), but in some mountainous areas annual rainfall often reaches 350 mm (13.8 in). Rain in the coastal region falls in short, torrential bursts during the winter months, sometimes resulting in floods in ordinarily dry wadi beds. The region

2907-579: A major expansion of Antarctic glaciers. This severed the connection between the Indian Ocean and the Mediterranean Sea and formed the present land connection between Afro-Arabia and Eurasia. The subsequent uplift of mountains in the western Mediterranean region and a global fall in sea levels combined to cause a temporary drying up of the Mediterranean Sea (known as the Messinian salinity crisis ) near

3060-480: A major expansion of grass-grazer ecosystems . Herds of large, swift grazers were hunted by predators across broad sweeps of open grasslands , displacing desert, woodland, and browsers . The higher organic content and water retention of the deeper and richer grassland soils , with long-term burial of carbon in sediments, produced a carbon and water vapor sink. This, combined with higher surface albedo and lower evapotranspiration of grassland, contributed to

3213-478: A much shallower depth to basement in the Hajar Mountains and a deeper depth to basement in the foreland basin to the west. This has implications on economic geology such as the mining for precious minerals and the extraction of oil and gas. The late Cretaceous obduction event created the proto-Hajar Mountains. However, this topography subsided and shallow marine sedimentation covered the region, beginning in

3366-607: A permanent military base in the emirate of Abu Dhabi. The UAE joined international military operations in Libya in March 2011. On 2 November 2004, the UAE's first president, Sheikh Zayed bin Sultan Al Nahyan , died. Sheikh Khalifa bin Zayed Al Nahyan was elected as the president of the UAE . Sheikh Mohammed bin Zayed Al Nahyan succeeded Sheikh Khalifa as crown prince of Abu Dhabi. In January 2006, Sheikh Maktoum bin Rashid Al Maktoum ,

3519-447: A series of nappes ( allochthonous rocks) that were transported from the northeast to the southwest horizontally for more than 300 km (190 mi). This was a major tectonic event during the late Cretaceous . This process is called obduction , where Permian to middle Cretaceous continental slope-rise (shallow to deep marine) sedimentary rocks and late Cretaceous oceanic crust ( Semail ophiolite ) were thrust (obducted) above

3672-578: A significant drop in atmospheric carbon dioxide levels. Both continental and oceanic thermal gradients in mid-latitudes during the Early Miocene were very similar to those in the present. Global cooling caused the East Asian Summer Monsoon (EASM) to begin to take on its modern form during the Early Miocene. From 22.1 to 19.7 Ma, the Xining Basin experienced relative warmth and humidity amidst

3825-695: A significant local decline along the northeastern coast of Australia during the Tortonian, most likely due to warming seawater. Cetaceans attained their greatest diversity during the Miocene, with over 20 recognized genera of baleen whales in comparison to only six living genera. This diversification correlates with emergence of gigantic macro-predators such as megatoothed sharks and raptorial sperm whales . Prominent examples are O. megalodon and L. melvillei . Other notable large sharks were O. chubutensis , Isurus hastalis , and Hemipristis serra . Crocodilians also showed signs of diversification during

3978-627: A zone of low rainfall in the Late Miocene. The Indian Plate continued to collide with the Eurasian Plate , creating new mountain ranges and uplifting the Tibetan Plateau , resulting in the rain shadowing and aridification of the Asian interior. The Tian Shan experienced significant uplift in the Late Miocene, blocking westerlies from coming into the Tarim Basin and drying it as a result. At

4131-461: Is 86.7% of the country's total area, excluding the islands. It has a coastline extending for more than 400 km (250 mi) and is divided for administrative purposes into three major regions. The Emirate of Dubai extends along the Persian Gulf coast of the UAE for approximately 72 km (45 mi). Dubai has an area of 3,885 square kilometres (1,500 square miles), which is equivalent to 5% of

4284-434: Is allocated to the UAE's central budget. The UAE uses the title Sheikh instead of Emir to refer to the rulers of individual emirates. The title is used due to the sheikhdom styled governing system in adherence to the culture of tribes of Arabia , where Sheikh means leader, elder, or the tribal chief of the clan who partakes in shared decision making with his followers. The president and vice president are elected by

4437-530: Is annually ranked as "Not Free" in Freedom House 's annual Freedom in the World report, which measures civil liberties and political rights. The UAE also ranks poorly in the annual Reporters without Borders ' Press Freedom Index . The Bertelsmann Transformation Index describes the UAE as a "moderate monarchy". The country was ranked 91 out of 137 states and is far below the average scoring for development towards

4590-429: Is at Dubai, although other ports have been dredged at Abu Dhabi, Sharjah, and elsewhere. Numerous islands are found in the Persian Gulf, and the ownership of some of them has been the subject of international disputes with both Iran and Qatar . The smaller islands, as well as many coral reefs and shifting sandbars, are a menace to navigation. Strong tides and occasional windstorms further complicate ship movements near

4743-449: Is categorized as desert climate. The hottest months are July and August, when average maximum temperatures reach above 45 °C (113 °F) on the coastal plain . In the Hajar Mountains, temperatures are considerably lower, a result of increased elevation. Average minimum temperatures in January and February are between 10 and 14 °C (50 and 57 °F). During the late summer months,

4896-479: Is concern in the geological community that with the development of infrastructure these rocks that contain a great deal of information will be excavated and destroyed. The central section of the Hajar is the highest and wildest terrain in the country. Jabal Shams is the highest of the range, followed by Jebel Akhdar . The latter and the smaller Jebel Nakhl range are bounded on the east by the low Samail Valley (which leads northeast to Muscat ). East of Samail are

5049-568: Is in the south near the undefined border with Saudi Arabia. About 100 km (62 mi) to the northeast of Liwa is the Al-Buraimi oasis, which extends on both sides of the Abu Dhabi-Oman border. Lake Zakher in Al Ain is a human-made lake near the border with Oman that was created from treated waste water. Prior to withdrawing from the area in 1971, Britain delineated the internal borders among

5202-508: Is jointly controlled by Oman and Ajman, the other by Fujairah and Sharjah. There is an Omani exclave surrounded by UAE territory, known as Wadi Madha . It is located halfway between the Musandam peninsula and the rest of Oman in the Emirate of Sharjah . It covers approximately 75 square kilometres (29 square miles) and the boundary was settled in 1969. The north-east corner of Madha is closest to

5355-663: Is of particular interest to geologists and palaeoclimatologists because major phases of the geology of the Himalaya occurred during that epoch, affecting monsoonal patterns in Asia, which were interlinked with glacial periods in the northern hemisphere. The Miocene faunal stages from youngest to oldest are typically named according to the International Commission on Stratigraphy : Regionally, other systems are used, based on characteristic land mammals; some of them overlap with

5508-544: Is prone to occasional, violent dust storms , which can severely reduce visibility. On 28 December 2004, snow was recorded in the UAE for the first time, in the Jebel Jais mountain cluster in Ras al-Khaimah. A few years later, there were more sightings of snow and hail. The Jebel Jais mountain cluster has experienced snow only twice since records began. The United Arab Emirates is a federal constitutional monarchy made up from

5661-607: Is situated in the Middle East , bordering the Gulf of Oman and the Persian Gulf , between Oman and Saudi Arabia ; it is in a strategic location slightly south of the Strait of Hormuz , a vital transit point for world crude oil . The UAE lies between 22°30' and 26°10' north latitude and between 51° and 56°25′ east longitude. It shares a 530-kilometre (330 mi) border with Saudi Arabia on

5814-478: Is some debate over whether the topography of the Hajar Mountains is due to thin or thick-skinned tectonics (if basement rocks were faulted during collision to create uplift due to thrust faults). Recent Bouguer gravity and magnetotelluric geophysical data suggest deep basement faults that have been activated as thrust faults during the collisional event that obducted the Semail Ophiolite. This has resulted in

5967-491: Is the chief executive branch of the government presided over by the prime minister. The prime minister, who is appointed by the Federal Supreme Council , appoints the ministers. The Council of Ministers is made up of 22 members and manages all internal and foreign affairs of the federation under its constitutional and federal law. In December 2019, the UAE became the only Arab country, and one of only five countries in

6120-579: Is the first geological epoch of the Neogene Period and extends from about 23.03 to 5.333 million years ago (Ma). The Miocene was named by Scottish geologist Charles Lyell ; the name comes from the Greek words μείων ( meíōn , "less") and καινός ( kainós , "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene followed

6273-483: Is the most spoken language and the language of business. The United Arab Emirates' oil and natural gas reserves are the world's seventh and seventh-largest , respectively. Zayed bin Sultan Al Nahyan , ruler of Abu Dhabi and the country's first president, oversaw the development of the Emirates by investing oil revenues into healthcare, education, and infrastructure. The country has the most diversified economy among

6426-582: The Eocene Epoch around 45-40 Ma. This episode saw the reactivation of cretaceous thrust faults and the development of long and short wavelength folding of Paleocene marine sediments that infilled previous foredeep accommodation. Low temperature thermodchronometry of apatite grains has given ages to this deformation and subsequent exhumation of the mountain belt. Exhumation occurred in two states, first between 45 and 40 Ma and again from 20 to 15 Ma. This later unroofing could also be related to tectonic uplift in

6579-738: The Federal Supreme Council . Usually, the Head of the Al Nahyan family, who are based in Abu Dhabi, holds the presidency and the Head of the Al Maktoum family, based in Dubai, the prime ministership. All prime ministers but one have served concurrently as vice president. The federal government is composed of three branches: The UAE e-Government is the extension of the UAE federal government in its electronic form. The UAE's Council of Ministers ( Arabic : مجلس الوزراء )

6732-539: The Middle Miocene Climate Transition (MMCT). Abrupt increases in opal deposition indicate this cooling was driven by enhanced drawdown of carbon dioxide via silicate weathering. The MMCT caused a sea surface temperature (SST) drop of approximately 6 °C in the North Atlantic. The drop in benthic foraminiferal δ O values was most noticeable in the waters around Antarctica, suggesting cooling

6885-512: The Oligocene and preceded the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages . The Miocene boundaries are not marked by distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing

7038-517: The Paleocene . Paleocene to Eocene sedimentary rocks are found at 2,200 m (7,200 ft) above sea level within the Hajar, and are folded . This indicates that the present day topography formed after the late Eocene . The exact timing is debated, and various interpretations indicate the topography formed anywhere between the late Eocene through to the Miocene . The driving forces that formed

7191-655: The Red Sea in the Horn of Africa . For example, the tree Ceratonia oreothauma is found here and also in Somalia . A number of birds are found in the mountains including Egyptian and lappet-faced vultures ( Torgos tracheliotus ). Mammals include mountain gazelles ( Gazella gazella ) and the Arabian tahr ( Arabitragus jayakari ). Other endemic species include a number of geckos and lizards: Asaccus montanus , Asaccus platyrhynchus and

7344-521: The Royal Navy to defend the sheikhdoms . On 24 January 1968, British Prime Minister Harold Wilson announced the government's decision, reaffirmed in March 1971 by Prime Minister Edward Heath , to end the treaty relationships with the seven trucial sheikhdoms. Days after the announcement, the ruler of Abu Dhabi, Sheikh Zayed bin Sultan Al Nahyan , fearing vulnerability, tried to persuade the British to honour

7497-627: The United Kingdom represented Abu Dhabi and Oman in their dispute with Saudi Arabia over the Buraimi Oasis . A 1974 agreement between Abu Dhabi and Saudi Arabia seemed to have settled the Abu Dhabi-Saudi border dispute , but this has not been ratified. The UAE's border with Oman was ratified in 2008. PDTC continued its onshore exploration away from the disputed area, drilling five more bore holes that were also dry. However, on 27 October 1960,

7650-609: The Wadi Suq culture from 2,000 to 1,300 BCE. From 1,200 BCE to the advent of Islam in Eastern Arabia, through three distinctive Iron Ages and the Mleiha period, the area was variously occupied by the Achaemenids and other forces, and saw the construction of fortified settlements and extensive husbandry thanks to the development of the falaj irrigation system. The spread of Islam to

7803-550: The carbon cycle occurred approximately 6 Ma, causing continental carbon reservoirs to no longer expand during cold spells, as they had done during cold periods in the Oligocene and most of the Miocene. At the end of the Miocene, global temperatures rose again as the amplitude of Earth's obliquity increased, which caused increased aridity in Central Asia. Around 5.5 Ma, the EAWM underwent a period of rapid intensification. Life during

7956-481: The mantle , and then exhumed back to the surface. This exhumation event created possibly the largest megasheath fold on Earth, the Wadi Mayh megasheath fold. The common view is that these eclogites were originally basic volcanic rocks within the leading edge of the continental crust of the Arabian Plate . This leading edge was then subducted by a NE-dipping subduction zone . However, some geologists have interpreted that these eclogites were subducted through

8109-417: The " Oman proper ". Since Jabal Akhdar and mountains in its vicinity are west of the valley, they may be regarded as Western Hajar. In the region of Tawam , which includes the adjacent settlements of Al-Buraimi and Al Ain , on the border of Oman and the UAE Emirate of Abu Dhabi , lies the outlier of Jebel Hafeet , which measures 1,100–1,400 m (3,600–4,600 ft) in height. Due to its proximity to

8262-424: The Arabian Peninsula under the newly emerging Rashidun Caliphate . In 637, Julfar (in the area of today's Ras Al Khaimah ) was an important port that was used as a staging post for the Islamic invasion of the Sasanian Empire . The area of the Al Ain / Buraimi Oasis was known as Tu'am and was an important trading post for camel routes between the coast and the Arabian interior. The earliest Christian site in

8415-409: The British promised to protect the Trucial Coast from all aggression by sea and to help in case of land attack. British maritime policing meant that pearling fleets could operate in relative security. However, the British prohibition of the slave trade meant an important source of income was lost to some sheikhs and merchants. In 1869, the Qubaisat tribe settled at Khor Al Adaid and tried to enlist

8568-429: The British treaty relationship was to expire in December of that year. Fears of vulnerability were realised the day before independence. An Iranian destroyer group broke formation from an exercise in the lower Gulf, sailing to the Tunb islands . The islands were taken by force, civilians and Arab defenders alike allowed to flee. A British warship stood idle during the course of the invasion. A destroyer group approached

8721-399: The British-Trucial Sheikhdoms treaty expired on 1 December 1971, both emirates became fully independent. On 2 December 1971, six of the emirates (Abu Dhabi, Ajman, Dubai, Fujairah, Sharjah, and Umm Al Quwain) agreed to enter into a union named the United Arab Emirates. Ras al-Khaimah joined later, on 10 January 1972. In February 1972, the Federal National Council (FNC) was created; it was

8874-417: The Central Paratethys, cut off from sources of freshwater input by its separation from the Eastern Paratethys. From 13.36 to 12.65 Ma, the Central Paratethys was characterised by open marine conditions, before the reopening of the Bârlad Strait resulted in a shift to brackish-marine conditions in the Central Paratethys, causing the Badenian-Sarmatian Extinction Event. As a result of the Bârlad Strait's reopening,

9027-721: The Early to the Middle Miocene. Europe's large mammal diversity significantly declined during the Late Miocene. In the Early Miocene, several Oligocene groups were still diverse, including nimravids , entelodonts , and three-toed equids. As in the previous Oligocene Epoch, oreodonts were still diverse, only to disappear in the earliest Pliocene. During the later Miocene mammals were more modern, with easily recognizable canids , bears , red pandas , procyonids , equids , beavers , deer , camelids , and whales , along with now-extinct groups like borophagine canids , certain gomphotheres , three-toed horses , and hornless rhinos like Teleoceras and Aphelos . The late Miocene also marks

9180-402: The East Antarctic Ice Sheet (EAIS) was highly dynamic during the Early Miocene. The Miocene began with the Early Miocene Cool Event (Mi-1) around 23 million years ago, which marked the start of the Early Miocene Cool Interval (EMCI). This cool event occurred immediately after the Oligocene-Miocene Transition (OMT) during a major expansion of Antarctica's ice sheets, but was not associated with

9333-399: The East Asian Winter Monsoon (EAWM) became stronger synchronously with a southward shift of the subarctic front. Greenland may have begun to have large glaciers as early as 8 to 7 Ma, although the climate for the most part remained warm enough to support forests there well into the Pliocene. Zhejiang, China was noticeably more humid than today. In the Great Rift Valley of Kenya , there

9945-508: The Greater and the Lesser Tunbs, when Iran captured them during the British rule, resulting in disputes with Iran that remain unresolved. The UAE also disputes claim on other islands against the neighboring state of Qatar. The largest emirate, Abu Dhabi , accounts for 87% of the UAE's total area, 67,340 square kilometres (26,000 sq mi). The smallest emirate, Ajman , encompasses only 259 km (100 sq mi). The UAE coast stretches for nearly 650 km (404 mi) along

10098-436: The Gulf . British expeditions to protect their Indian trade routes led to campaigns against Ras Al Khaimah and other harbours along the coast, including the Persian Gulf campaign of 1809 and the more successful campaign of 1819 . The following year, Britain and a number of local rulers signed a maritime truce , giving rise to the term Trucial States , which came to define the status of the coastal emirates. A further treaty

10251-415: The Hajar is also debated. Many geologists relate the Zagros Collision as the reason for the uplift forming the mountains, as currently the Musandam Peninsula (northwest corner of the mountain range) is uplifting due to this collision. However, Jabal Shams , the highest peak of the central mountains is over 300 km (190 mi) away from this zone. In addition, there is no major seismicity within

11169-694: The Late Miocene, the Earth's climate began to display a high degree of similarity to that of the present day . The 173 kyr obliquity modulation cycle governed by Earth's interactions with Saturn became detectable in the Late Miocene. By 12 Ma, Oregon was a savanna akin to that of the western margins of the Sierra Nevada of northern California . Central Australia became progressively drier, although southwestern Australia experienced significant wettening from around 12 to 8 Ma. The South Asian Winter Monsoon (SAWM) underwent strengthening ~9.2–8.5 Ma. From 7.9 to 5.8 Ma,

11322-567: The Miocene Epoch was mostly supported by the two newly formed biomes , kelp forests and grasslands . Grasslands allow for more grazers, such as horses , rhinoceroses , and hippos . Ninety-five percent of modern plants existed by the end of this epoch . Modern bony fish genera were established. A modern-style latitudinal biodiversity gradient appeared ~15 Ma. The coevolution of gritty , fibrous, fire-tolerant grasses and long-legged gregarious ungulates with high-crowned teeth , led to

11475-449: The Miocene. The largest form among them was a gigantic caiman Purussaurus which inhabited South America. Another gigantic form was a false gharial Rhamphosuchus , which inhabited modern age India . A strange form, Mourasuchus also thrived alongside Purussaurus . This species developed a specialized filter-feeding mechanism, and it likely preyed upon small fauna despite its gigantic size. The youngest members of Sebecidae ,

11628-676: The Miocene–Pliocene boundary, the Strait of Gibraltar opened, and the Mediterranean refilled. That event is referred to as the " Zanclean flood ". Also during the early Miocene (specifically the Aquitanian and Burdigalian Stages), the apes first evolved, began diversifying, and became widespread throughout the Old World . Around the end of this epoch, the ancestors of humans had split away from

11781-534: The North American Great Plains and in Argentina . The global trend was towards increasing aridity caused primarily by global cooling reducing the ability of the atmosphere to absorb moisture, particularly after 7 to 8 million years ago. Uplift of East Africa in the late Miocene was partly responsible for the shrinking of tropical rain forests in that region, and Australia got drier as it entered

11934-705: The Oligocene–Miocene transgression. As the southern Andes rose in the Middle Miocene (14–12 million years ago) the resulting rain shadow originated the Patagonian Desert to the east. Far northern Australia was monsoonal during the Miocene. Although northern Australia is often believed to have been much wetter during the Miocene, this interpretation may be an artefact of preservation bias of riparian and lacustrine plants; this finding has itself been challenged by other papers. Western Australia, like today,

12087-621: The Persian Gulf region. By the 18th century, the Bani Yas confederation was the dominant force in most of the area now known as Abu Dhabi, while the Northern Al Qawasim (Al Qasimi) dominated maritime commerce. The Portuguese maintained an influence over the coastal settlements, building forts in the wake of the bloody 16th-century conquests of coastal communities by Albuquerque and the Portuguese commanders who followed him – particularly on

12240-547: The Qiongdongnan Basin in the northern South China Sea indicates the Pearl River was a major source of sediment flux into the sea during the Early Miocene and was a major fluvial system as in the present. During the Oligocene and Early Miocene, the coast of northern Brazil, Colombia, south-central Peru , central Chile and large swathes of inland Patagonia were subject to a marine transgression . The transgressions in

12393-582: The Trucial States. In 1922, the British government secured undertakings from the rulers of the Trucial States not to sign concessions with foreign companies without their consent. Aware of the potential for the development of natural resources such as oil, following finds in Persia (from 1908) and Mesopotamia (from 1927), a British-led oil company, the Iraq Petroleum Company (IPC), showed an interest in

12546-443: The UAE was first discovered in the 1990s, an extensive monastic complex on what is now known as Sir Bani Yas Island and which dates back to the seventh century. Thought to be Nestorian and built in 600 CE, the church appears to have been abandoned peacefully in 750 CE. It forms a rare physical link to a legacy of Christianity, which is thought to have spread across the peninsula from 50 to 350 CE following trade routes. Certainly, by

12699-628: The Upper Thamama rock formation. This was the first commercial discovery of the Trucial Coast, leading to the first exports of oil in 1962. ADMA made further offshore discoveries at Zakum and elsewhere, and other companies made commercial finds such as the Fateh oilfield off Dubai and the Mubarak field off Sharjah (shared with Iran). Meanwhile, onshore exploration was hindered by territorial disputes. In 1955,

12852-487: The activity of the Columbia River Basalts and enhanced by decreased albedo from the reduction of deserts and expansion of forests. Climate modelling suggests additional, currently unknown, factors also worked to create the warm conditions of the MMCO. The MMCO saw the expansion of the tropical climatic zone to much larger than its current size. The July ITCZ, the zone of maximal monsoonal rainfall, moved to

13005-531: The ancestors of the chimpanzees and had begun following their own evolutionary path during the final Messinian Stage (7.5–5.3 Ma) of the Miocene. As in the Oligocene before it, grasslands continued to expand, and forests to dwindle. In the seas of the Miocene, kelp forests made their first appearance and soon became one of Earth's most productive ecosystems. The plants and animals of the Miocene were recognizably modern. Mammals and birds were well established. Whales , pinnipeds , and kelp spread. The Miocene

13158-567: The area of Khasab in northern part of the Musandam . Like the Ru'us al-Jibal , the area of Jebel Hafeet is noted for hosting rare flora and fauna. For example, in February 2019, an Arabian caracal was sighted here, and in March, a Blanford's fox , which has also been reported in the mountains of Ras Al-Khaimah. In September 2024 it was reported that the rare white-edged rock brown butterflies were spotted in

13311-471: The area. The Hajar are extensively grazed by domestic goats, camels and donkeys and the landscape has been cleared in parts for urban areas and for mining, which has damaged both vegetation and water supplies and uprooted traditional rural land management behaviours. Poaching of wildlife is another issue. The Oman government has created the Wadi Sareen Reserve and an area of Jebel Qahwan-Jebal Sebtah in

13464-472: The aridity of the former. Unequivocally-recognizable dabbling ducks , plovers , typical owls , cockatoos and crows appear during the Miocene. By the epoch's end, all or almost all modern bird groups are believed to have been present; the few post-Miocene bird fossils which cannot be placed in the evolutionary tree with full confidence are simply too badly preserved, rather than too equivocal in character. Marine birds reached their highest diversity ever in

13617-572: The attempt of the establishment of an Islamist state in the UAE. Mindful of the protests in nearby Bahrain, in November 2012 the UAE outlawed online mockery of its government or attempts to organise public protests through social media. On 29 January 2020, the COVID-19 pandemic was confirmed to have reached the UAE . Two months later, in March, the government announced the closure of shopping malls, schools, and places of worship, in addition to imposing

13770-619: The beginning of the Miocene, the northern margin of the Arabian plate, then part of the African landmass, collided with Eurasia; as a result, the Tethys seaway continued to shrink and then disappeared as Africa collided with Eurasia in the Turkish – Arabian region. The first step of this closure occurred 20 Ma, reducing water mass exchange by 90%, while the second step occurred around 13.8 Ma, coincident with

13923-473: The central mountains, indicating that the mountains are not currently deforming, even though the Zagros collision is. This indicates that the uplift that created the present day topography occurred in the past, possibly before the initiation of the Zagros collision , by a mechanism that is not fully understood. Oman's geological record is extremely valuable to geologists, and needs to be preserved . It contains

14076-533: The company discovered oil in commercial quantities at the Murban No. 3 well on the coast near Tarif. In 1962, PDTC became the Abu Dhabi Petroleum Company . As oil revenues increased, the ruler of Abu Dhabi, Zayed bin Sultan Al Nahyan , undertook a massive construction program, building schools, housing, hospitals, and roads. When Dubai's oil exports commenced in 1969, Sheikh Rashid bin Saeed Al Maktoum ,

14229-473: The connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and hominoids into Eurasia. During the late Miocene, the connections between the Atlantic and Mediterranean closed, causing the Mediterranean Sea to almost completely evaporate. This event is referred to as the " Messinian salinity crisis ". Then, at

14382-437: The council. The council was terminated once the United Arab Emirates was formed. The tribal nature of society and the lack of definition of borders between emirates frequently led to disputes, settled either through mediation or, more rarely, force. The Trucial Oman Scouts was a small military force used by the British to keep the peace. In 1953, a subsidiary of BP , D'Arcy Exploration Ltd, obtained an offshore concession from

14535-426: The country's total area, excluding the islands. The Emirate of Sharjah extends along approximately 16 km (10 mi) of the UAE's Persian Gulf coastline and for more than 80 km (50 mi) into the interior. The northern emirates which include Fujairah, Ajman, Ras al-Khaimah, and Umm al-Qaiwain all have a total area of 3,881 square kilometres (1,498 square miles). There are two areas under joint control. One

14688-566: The course of this epoch . The youngest representatives of Choristodera , an extinct order of aquatic reptiles that first appeared in the Middle Jurassic , are known from the Miocene of Europe, belonging to the genus Lazarussuchus , which had been the only known surviving genus of the group since the beginning of the Eocene. The last known representatives of the archaic primitive mammal order Meridiolestida , which dominated South America during

14841-428: The east and northeast, and with Saudi Arabia to the southwest; as well as maritime borders in the Persian Gulf with Qatar and Iran , and with Oman in the Gulf of Oman . As of 2024 , the UAE has an estimated population of over 10 million, of which 11% are Emiratis; Dubai is the most populous city and is an international hub. Islam is the official religion and Arabic is the official language, while English

14994-487: The east coast at Muscat , Sohar , and Khor Fakkan . The southern coast of the Persian Gulf was known to the British as the " Pirate Coast ", as boats of the Al Qawasim federation harassed British-flagged shipping from the 17th century into the 19th. The charge of piracy is disputed by modern Emirati historians, including the current ruler of Sharjah, Sheikh Sultan Al Qasimi , in his 1986 book The Myth of Arab Piracy in

15147-640: The east. Here, oceanic crust of the Arabian Plate is subducted northwards beneath Eurasia , called the Makran subduction zone . The Hajar Mountains are the product of polyphase mountain building . Uplift and deformation of the Arabian passive margin began during the late cretaceous as the African-Arabian Plate began to subduct under the South Tethyan Oceanic Plate imitated at an intra oceanic subduction zone . This initiation may have been

15300-512: The emirates contested jurisdiction over more than a dozen enclaves. The UAE contains the following terrestrial ecoregions: Al Hajar montane woodlands and shrublands, Gulf of Oman desert and semi-desert , and Al-Hajar foothill xeric woodlands and shrublands . The oases grow date palms , acacia , and eucalyptus trees. In the desert, the flora is very sparse and consists of grasses and thorn bushes. The indigenous fauna had come close to extinction because of intensive hunting, which has led to

15453-564: The end of the Miocene due to increased habitat uniformity. The expansion of grasslands in North America also led to an explosive radiation among snakes. Previously, snakes were a minor component of the North American fauna, but during the Miocene, the number of species and their prevalence increased dramatically with the first appearances of vipers and elapids in North America and the significant diversification of Colubridae (including

15606-539: The end of the Miocene. The Paratethys underwent a significant transgression during the early Middle Miocene. Around 13.8 Ma, during a global sea level drop, the Eastern Paratethys was cut off from the global ocean by the closure of the Bârlad Strait, effectively turning it into a saltwater lake. From 13.8 to 13.36 Ma, an evaporite period similar to the later Messinian salinity crisis in the Mediterranean ensued in

15759-612: The enigmatic Saint Bathans Mammal . Microbial life in the igneous crust of the Fennoscandian Shield shifted from being dominated by methanogens to being primarily composed of sulphate-reducing prokaryotes . The change resulted from fracture reactivation during the Pyrenean-Alpine orogeny, enabling sulphate-reducing microbes to permeate into the Fennoscandian Shield via descending surficial waters. Diatom diversity

15912-685: The establishment of seasonal and semi-seasonal settlements and centres. These formed tribal groupings whose names are still carried by modern Emiratis, including the Bani Yas and Al Bu Falah of Abu Dhabi , Al Ain, Liwa , and the west coast; the Dhawahir , Awamir, Al Ali , and Manasir of the interior; the Sharqiyin of the east coast; and the Qawasim to the north. With the expansion of European colonial empires , Portuguese, English, and Dutch forces appeared in

16065-461: The evolution of both groups into modern representatives. The early Miocene Saint Bathans Fauna is the only Cenozoic terrestrial fossil record of the landmass, showcasing a wide variety of not only bird species, including early representatives of clades such as moa , kiwi and adzebills , but also a diverse herpetofauna of sphenodontians , crocodiles and turtles as well as a rich terrestrial mammal fauna composed of various species of bats and

16218-499: The expansion of grasslands not to a CO 2 drop but to the increasing seasonality and aridity, coupled with a monsoon climate, which made wildfires highly prevalent compared to before. The Late Miocene expansion of grasslands had cascading effects on the global carbon cycle, evidenced by the imprint it left in carbon isotope records. Cycads between 11.5 and 5 million years ago began to rediversify after previous declines in variety due to climatic changes, and thus modern cycads are not

16371-711: The extinction of the last-surviving members of the hyaenodonts . Islands began to form between South and North America in the Late Miocene, allowing ground sloths like Thinobadistes to island-hop to North America. The expansion of silica-rich C 4 grasses led to worldwide extinctions of herbivorous species without high-crowned teeth . Mustelids diversified into their largest forms as terrestrial predators like Ekorus , Eomellivora , and Megalictis and bunodont otters like Enhydriodon and Sivaonyx appeared. Eulipotyphlans were widespread in Europe, being less diverse in Southern Europe than farther north due to

16524-405: The fifth century, Oman had a bishop named John – the last bishop of Oman being Etienne, in 676 CE. The harsh desert environment led to the emergence of the "versatile tribesman", nomadic groups who subsisted due to a variety of economic activities, including animal husbandry, agriculture, and hunting. The seasonal movements of these groups led not only to frequent clashes between groups but also to

16677-604: The findings of marine invertebrate fossils of both Atlantic and Pacific affinity in La Cascada Formation . Connection would have occurred through narrow epicontinental seaways that formed channels in a dissected topography . The Antarctic Plate started to subduct beneath South America 14 million years ago in the Miocene, forming the Chile Triple Junction . At first the Antarctic Plate subducted only in

16830-628: The freedom of the press are severely repressed. Stone tools recovered reveal a settlement of people from Africa some 127,000 years ago and a stone tool used for butchering animals discovered on the Arabian coast suggests an even older habitation from 130,000 years ago. In time, lively trading links developed with civilisations in Mesopotamia , Iran, and the Harappan culture of the Indus Valley. This contact persisted and became wider, probably motivated by

16983-401: The highest peak at 3,009 m (9,872 ft) in the central region of the mountains. Currently, the Arabian Plate is moving north relative to the Eurasian Plate at 2–3 cm (0.79–1.18 in) per year. Continental collision is occurring at the Zagros fold and thrust belt west of the Musandam Peninsula . This collisional plate boundary transitions into a subduction zone , towards

17136-460: The human lineage) appeared in Africa at the very end of the Miocene, including Sahelanthropus , Orrorin , and an early form of Ardipithecus ( A. kadabba ). The chimpanzee–human divergence is thought to have occurred at this time. The evolution of bipedalism in apes at the end of the Miocene instigated an increased rate of faunal turnover in Africa. In contrast, European apes met their end at

17289-617: The island of Abu Musa as well. But there, Sheikh Khalid bin Mohammed Al Qasimi had already negotiated with the Iranian shah, and the island was quickly leased to Iran for $ 3 million a year. Meanwhile, Saudi Arabia laid claim to swathes of Abu Dhabi. Originally intended to be part of the proposed Federation of Arab Emirates, Bahrain became independent in August, and Qatar in September 1971. When

17442-587: The lake levels of the Eastern Paratethys dropped as it once again became a sea. The Fram Strait opened during the Miocene and acted as the only throughflow for Atlantic Water into the Arctic Ocean until the Quaternary period. Due to regional uplift of the continental shelf, this water could not move through the Barents Seaway in the Miocene. The modern day Mekong Delta took shape after 8 Ma. Geochemistry of

17595-564: The main range, it may be treated as one of the Hajar Mountains, sensu lato . This mountain has ridges which stretch northwards to the city of Al Ain. The northernmost mountains of the Hajar range are found on the Musandam Peninsula. For this reason, the phrase Ru'us al-Jibal ("Heads of the Mountains") is applied to them, or the peninsula itself. Despite being physically part of the western Hajar, they differ in geology and hydrology to

17748-404: The members of the Gulf Cooperation Council (GCC). In the 21st century, the UAE has become less reliant on oil and gas and is economically focusing on tourism and business. The UAE is considered a middle power . It is also a member of the United Nations , Arab League , Organisation of Islamic Cooperation , OPEC , Non-Aligned Movement , World Trade Organization , and BRICS . The UAE is also

17901-438: The most complete ophiolite on Earth, of which it is most famous for among geologists. The ophiolite sequence has spectacular pillow basalt (Geotimes pillow lava), as well as exposures of the fossil crust-mantle boundary ( moho ). Generally, ophiolites are obducted prior to continental collision , which highly deforms the structure of the original oceanic crust . However, because continental collision has not occurred in

18054-483: The mountains are covered with shrubland at lower elevations, growing richer and then becoming woodland, including wild olive and fig trees between 3,630 and 8,250 ft (1,110 and 2,510 metres), and then higher still there are junipers . Fruit trees such as pomegranate and apricot are grown in the cooler valleys and in places there are rocky outcrops with little vegetation. The flora shows similarities with mountain areas of nearby Iran , as well as with areas along

18207-419: The nearby Zagros Mountains of Iran . The geology of the Hajar can be grouped into four major tectonostratigraphic groups. Group one are the pre- Permian basement rocks, a sedimentary sequence of clastics , carbonates and evaporites . Group two are a middle Permian to Late Cretaceous sequence of continental shelf carbonates , which were deposited unconformably above the basement. Group three are

18360-606: The new Islamic communities south of the Persian Gulf threatened to disintegrate, with insurrections against the Muslim leaders . Caliph Abu Bakr sent an army from the capital Medina which completed its reconquest of the territory ( the Ridda Wars ) with the Battle of Dibba in which 10,000 lives are thought to have been lost. This assured the integrity of the Caliphate and the unification of

18513-543: The north, increasing precipitation over southern China whilst simultaneously decreasing it over Indochina during the EASM. Western Australia was at this time characterised by exceptional aridity. In Antarctica, average summer temperatures on land reached 10 °C. In the oceans, the lysocline shoaled by approximately half of a kilometre during warm phases that corresponded to orbital eccentricity maxima. The MMCO ended around 14 million years ago, when global temperatures fell in

18666-510: The northeastern tip of the Arabian Peninsula is thought to have followed directly from a letter sent by the Islamic prophet Muhammad to the rulers of Oman in 630 CE. This led to a group of rulers travelling to Medina , converting to Islam, and subsequently driving a successful uprising against the unpopular Sassanids , who dominated the coast at the time. Following the death of Muhammad,

18819-493: The northern UAE Emirates of Sharjah , Ras Al-Khaimah and Fujairah , may also be called the Shumayliyyah ( شُمَيْلِيَّة ). In this region is Jebel Al-Ḥeben ( جَبَل ٱلْحبن ; 25°7′33″N 56°9′33″E  /  25.12583°N 56.15917°E  / 25.12583; 56.15917 ). The mountains are rich in plant life compared to most of Arabia, including a number of endemic species. The vegetation changes with altitude,

18972-523: The origin of many modern genera such as Nerodia , Lampropeltis , Pituophis and Pantherophis ). Arthropods were abundant, including in areas such as Tibet where they have traditionally been thought to be undiverse. Neoisopterans diversified and expanded into areas they previously were absent from, such as Madagascar and Australia. In the oceans, brown algae , called kelp , proliferated, supporting new species of sea life, including otters , fish and various invertebrates . Corals suffered

19125-462: The other half are elected. By law, the council members have to be equally divided between males and females. The FNC is restricted to a largely consultative role. The United Arab Emirates is an authoritarian federal monarchy . According to the New York Times , the UAE is "an autocracy with the sheen of a progressive, modern state". The UAE has been described as a "tribal autocracy" where

19278-542: The people of the Persian Gulf. The First World War had a severe impact on the industry, but it was the economic depression of the late 1920s and early 1930s, coupled with the invention of the cultured pearl , that wiped out the trade. The remnants of the trade eventually faded away shortly after the Second World War , when the newly independent Government of India imposed heavy taxation on imported pearls. The decline of pearling resulted in extreme economic hardship in

19431-463: The possible herpetotheriid Morotodon from the late Early Miocene of Uganda. Approximately 100 species of apes lived during this time , ranging throughout Africa, Asia and Europe and varying widely in size, diet, and anatomy. Due to scanty fossil evidence it is unclear which ape or apes contributed to the modern hominid clade, but molecular evidence indicates this ape lived between 18 and 13 million years ago. The first hominins ( bipedal apes of

19584-828: The preceding Oligocene and following Pliocene Epochs: Continents continued to drift toward their present positions. Of the modern geologic features, only the land bridge between South America and North America was absent, although South America was approaching the western subduction zone in the Pacific Ocean , causing both the rise of the Andes and a southward extension of the Meso-American peninsula. Mountain building took place in western North America , Europe , and East Asia . Both continental and marine Miocene deposits are common worldwide with marine outcrops common near modern shorelines. Well studied continental exposures occur in

19737-505: The prime minister of the UAE and the ruler of Dubai, died, and Sheikh Mohammed bin Rashid Al Maktoum assumed both roles. The first ever national elections were held on 16 December 2006. A number of voters chose half of the members of the Federal National Council . The UAE has largely escaped the Arab Spring , which other countries have experienced; however, 60 Emirati activists from Al Islah were apprehended for an alleged coup attempt and

19890-473: The protection treaties by offering to pay the full costs of keeping the British Armed Forces in the Emirates. The British Labour government rejected the offer. After Labour MP Goronwy Roberts informed Sheikh Zayed of the news of British withdrawal, the nine Persian Gulf sheikhdoms attempted to form a union of Arab emirates, but by mid-1971 they were still unable to agree on terms of union even though

20043-602: The region. The Anglo-Persian Oil Company (APOC, later to become British Petroleum , or BP) had a 23.75% share in IPC. From 1935, onshore concessions to explore for oil were granted by local rulers, with APOC signing the first one on behalf of Petroleum Concessions Ltd (PCL), an associate company of IPC. APOC was prevented from developing the region alone because of the restrictions of the Red Line Agreement , which required it to operate through IPC. A number of options between PCL and

20196-555: The rest of the range. The highest point in the UAE is located at Jebel Jais near Ras Al Khaimah , which measures 1,911 m (6,270 ft) from sea level, but since the summit is on the Omani side, Jabal ar Rahrah , measuring over 1,691 m (1.051 miles), has the highest peak in the UAE. The mountains bordering the Shamailiyyah ( شَمَيْلِيَّة ) coast on the Gulf of Oman, forming parts of

20349-596: The result of plate rotation due to the breakup of Gondwana . Similar to the modern convergence of the Australian passive margin under Eurasian oceanic crust, Arabian passive margin sediments became highly deformed and shortened forming an imbricated thrust belt. This also coincided with the emplacement of the Semail Ophiolite . By the early Maastrichtian , deformation ceased, and stable continental shelf conditions resumed. A second episode of deformation began during

20502-470: The rocks from groups one and two. Lastly, group four are late Cretaceous to Miocene shallow marine and terrestrial sedimentary rocks that were deposited on top of all three previous groups. The high topography is around two major culminations: Jabal Akhdar and Saih Hatat, which are large scale anticlines . The Saih Hatat culmination contains eclogite in the northeast at As Sifah. These rocks were subducted to about 80 km (50 mi) depth into

20655-546: The ruler of Abu Dhabi. BP joined with Compagnie Française des Pétroles (later Total ) to form operating companies, Abu Dhabi Marine Areas Ltd (ADMA) and Dubai Marine Areas Ltd (DUMA). A number of undersea oil surveys were carried out, including one led by the famous marine explorer Jacques Cousteau . In 1958, a floating platform rig was towed from Hamburg , Germany , and positioned over the Umm Shaif pearl bed, in Abu Dhabi waters, where drilling began. In March, it struck oil in

20808-406: The ruler of Dubai, was able to invest the revenues from the limited reserves found to spark the diversification drive that would create the modern global city of Dubai. By 1966, it had become clear that the British government could no longer afford to administer and protect the Trucial States , what is now the United Arab Emirates. British Members of Parliament (MPs) debated the preparedness of

20961-445: The seven constituent monarchies are led by tribal rulers in an autocratic fashion. There are no democratically elected institutions, and there is no formal commitment to free speech. According to human rights organisations, there are systematic human rights violations, including the torture and forced disappearance of government critics. The UAE ranks poorly in freedom indices measuring civil liberties and political rights . The UAE

21114-442: The seven emirates in order to preempt territorial disputes that might hamper formation of the federation. In general, the rulers of the emirates accepted the British interventions, but in the case of boundary disputes between Abu Dhabi and Dubai, and also between Dubai and Sharjah, conflicting claims were not resolved until after the UAE became independent. The most complicated borders were in the Western Hajar Mountains , where five of

21267-497: The shore. The UAE also has a stretch of the Al Bāţinah coast of the Gulf of Oman. The Musandam Peninsula , the very tip of Arabia by the Strait of Hormuz, and Madha are exclaves of Oman separated by the UAE. South and west of Abu Dhabi, vast, rolling sand dunes merge into the Rub al-Khali (Empty Quarter) of Saudi Arabia. The desert area of Abu Dhabi includes two important oases with adequate underground water for permanent settlements and cultivation. The extensive Liwa Oasis

21420-398: The southern shore of the Persian Gulf , briefly interrupted by an isolated outcrop of the Sultanate of Oman. Six of the emirates are situated along the Persian Gulf, and the seventh, Fujairah, is on the eastern coast of the peninsula with direct access to the Gulf of Oman. Most of the coast consists of salt pans that extend 8–10 km (5.0–6.2 mi) inland. The largest natural harbor

21573-531: The southernmost tip of Patagonia, meaning that the Chile Triple Junction lay near the Strait of Magellan . As the southern part of Nazca Plate and the Chile Rise became consumed by subduction the more northerly regions of the Antarctic Plate begun to subduct beneath Patagonia so that the Chile Triple Junction advanced to the north over time. The asthenospheric window associated to the triple junction disturbed previous patterns of mantle convection beneath Patagonia inducing an uplift of ca. 1 km that reversed

21726-432: The support of the Ottomans. Khor Al Adaid was claimed by Abu Dhabi at that time, a claim supported by the British. In 1906, the British Political Resident, Percy Cox , confirmed in writing to the ruler of Abu Dhabi, Zayed bin Khalifa Al Nahyan ('Zayed the Great'), that Khor Al Adaid belonged to his sheikhdom. During the 19th and early 20th centuries, the pearling industry thrived, providing both income and employment to

21879-413: The trade in copper from the Hajar Mountains , which commenced around 3,000 BCE. Sumerian sources talk of the Magan civilisation, which has been identified as encompassing the modern UAE and Oman. There are six periods of human settlement with distinctive behaviours in the region before Islam, which include the Hafit period from 3,200 to 2,600 BCE, the Umm Al Nar culture from 2,600 to 2,000 BCE, and

22032-410: The trucial rulers were signed, providing useful revenue for communities experiencing poverty following the collapse of the pearl trade. However, the wealth of oil which the rulers could see from the revenues accruing to surrounding countries remained elusive. The first bore holes in Abu Dhabi were drilled by IPC's operating company, Petroleum Development (Trucial Coast) Ltd (PDTC) at Ras Sadr in 1950, with

22185-440: The west coast of South America are thought to be caused by a regional phenomenon while the steadily rising central segment of the Andes represents an exception. While there are numerous registers of Oligocene–Miocene transgressions around the world it is doubtful that these correlate. It is thought that the Oligocene–Miocene transgression in Patagonia could have temporarily linked the Pacific and Atlantic Oceans, as inferred from

22338-436: The west, south, and southeast, and a 450-kilometre (280 mi) border with Oman on the southeast and northeast. The land border with Qatar in the Khor Al Adaid area is about nineteen kilometres (12 miles) in the northwest; however, it is a source of ongoing dispute . Following Britain's military departure from the UAE in 1971, and its establishment as a new state, the UAE laid claim to Iranian-occupied islands of Abu Musa and

22491-425: The world, to attain gender parity in a national legislative body, with its lower house 50 per cent women. The UAE is the only country in the world that has a Ministry of Tolerance , a Ministry of Happiness , and a Ministry of Artificial Intelligence. The UAE also has a virtual ministry called the Ministry of Possibilities, designed to find solutions to challenges and improve quality of life. The UAE also has

22644-423: Was Allodesmus . A ferocious walrus , Pelagiarctos may have preyed upon other species of pinnipeds including Allodesmus . Furthermore, South American waters witnessed the arrival of Megapiranha paranensis , which were considerably larger than modern age piranhas . New Zealand 's Miocene fossil record is particularly rich. Marine deposits showcase a variety of cetaceans and penguins , illustrating

22797-496: Was a gradual and progressive trend of increasing aridification, though it was not unidirectional, and wet humid episodes continued to occur. Between 7 and 5.3 Ma, temperatures dropped sharply again in the Late Miocene Cooling (LMC), most likely as a result of a decline in atmospheric carbon dioxide and a drop in the amplitude of Earth's obliquity, and the Antarctic ice sheet was approaching its present-day size and thickness. Ocean temperatures plummeted to near-modern values during

22950-405: Was arid, particularly so during the Middle Miocene. Climates remained moderately warm, although the slow global cooling that eventually led to the Pleistocene glaciations continued. Although a long-term cooling trend was well underway, there is evidence of a warm period during the Miocene when the global climate rivalled that of the Oligocene . The climate of the Miocene has been suggested as

23103-514: Was inversely correlated with carbon dioxide levels and global temperatures during the Miocene. Most modern lineages of diatoms appeared by the Late Miocene. There is evidence from oxygen isotopes at Deep Sea Drilling Program sites that ice began to build up in Antarctica about 36 Ma during the Eocene . Further marked decreases in temperature during the Middle Miocene at 15 Ma probably reflect increased ice growth in Antarctica. It can therefore be assumed that East Antarctica had some glaciers during

23256-464: Was most intense there. Around this time the Mi3b glacial event (a massive expansion of Antarctic glaciers) occurred. The East Antarctic Ice Sheet (EAIS) markedly stabilised following the MMCT. The intensification of glaciation caused a decoherence of sediment deposition from the 405 kyr eccentricity cycle. The MMWI ended about 11 Ma, when the Late Miocene Cool Interval (LMCI) started. A major but transient warming occurred around 10.8-10.7 Ma. During

23409-420: Was signed in 1843 and in 1853, the Perpetual Maritime Truce was agreed. To this was added the 'Exclusive Agreements', signed in 1892, which made the Trucial States a British protectorate. Under the 1892 treaty, the trucial sheikhs agreed not to dispose of any territory except to the British and not to enter into relationships with any foreign government other than the British without their consent. In return,
