In geology , a facies ( / ˈ f eɪ ʃ ɪ . iː z / FAY -shih-eez , US also / ˈ f eɪ ʃ iː z / FAY -sheez ; same pronunciation and spelling in the plural) is a body of rock with distinctive characteristics. The characteristics can be any observable attribute of rocks (such as their overall appearance, composition, or condition of formation) and the changes that may occur in those attributes over a geographic area. A facies encompasses all the characteristics of a rock including its chemical, physical, and biological features that distinguish it from adjacent rock.

25-487: The term "facies" was introduced by the Swiss geologist Amanz Gressly in 1838 and was part of his significant contribution to the foundations of modern stratigraphy , which replaced the earlier notions of Neptunism . Walther's law of facies, or simply Walther's law, named after the geologist Johannes Walther , states that the vertical succession of facies reflects lateral changes in environment. Conversely, it states that when

50-557: A facies series . Amanz Gressly Amanz Gressly (17 July 1814 – 13 April 1865) was a Swiss geologist and paleontologist . He introduced the use of the term facies in geology , and is considered one of the founders of modern stratigraphy and paleoecology . He initially studied medicine at Strasbourg , but his interest subsequently switched to geology, and from 1836 onward, he worked as an assistant to Louis Agassiz . In 1838 he published Observations géologiques sur le Jura Soleurois (Geological observations involving

75-476: A depositional environment "migrates" laterally, sediments of one depositional environment come to lie on top of another. In Russia the law is known as Golovkinsky-Walther's law, honoring also Nikolai A. Golovkinsky . A classic example of this law is the vertical stratigraphic succession that typifies marine transgressions and regressions . Ideally, a sedimentary facies is a distinctive rock unit that forms under certain conditions of sedimentation , reflecting

100-435: A group of "facies descriptors" which must be distinct, reproducible and exhaustive. A reliable facies description of an outcrop in the field would include: composition, texture, sedimentary structure(s), bedding geometry, nature of bedding contact, fossil content and colour. The sequence of minerals that develop during progressive metamorphism (that is, metamorphism at progressively higher temperatures and/or pressures) define

125-528: A particular process or environment. Sedimentary facies are either descriptive or interpretative. Sedimentary facies are bodies of sediment that are recognizably distinct from adjacent sediments that resulted from different depositional environments. Generally, geologists distinguish facies by the aspect of the rock or sediment being studied. Facies based on petrological characters (such as grain size and mineralogy ) are called lithofacies , whereas facies based on fossil content are called biofacies . A facies

The record of cycling this distance is 4 days, 22 hours, and 18 minutes which was performed by a group of five men from Rye in Oslo, in July 2003. Footage from the North Cape is featured frequently in films and television, most notably in the 2014 action comedy film Børning , which revolves around an illegal street race from south of Oslo to

The bicycle race started in Hammerfest , finishing on North Cape and was won by Norwegian, Lars Petter Nordhaug for Visma–Lease a Bike in a time of 4 hours 51 minutes 3 seconds. Norge På Langs

The North Cape was named by the Englishman Steven Borough , captain of the Edward Bonaventure , which sailed past in 1553 in search of the Northeast Passage . The North Cape became a popular tourist destination during

250-623: Is in Nordkapp Municipality in Finnmark county, Norway . The European route E69 motorway (highway) has its northern terminus at North Cape, which makes it the northernmost point in Europe that can be accessed by car and makes the E69 the northernmost public road in Europe. The plateau is a popular tourist attraction . The cape includes a 307-metre-high cliff (1,007 ft) with a large flat plateau on top, where visitors, weather permitting, can watch

275-638: Is usually further subdivided. The characteristics of the rock unit come from the depositional environment and from the original composition. Sedimentary facies reflect their depositional environment, each facies being a distinct kind of sediment for that area or environment. Since its inception in 1838, the facies concept has been extended to related geological concepts. For example, characteristic associations of organic microfossils, and particulate organic material, in rocks or sediments, are called palynofacies . Discrete seismic units are similarly referred to as seismic facies. Sedimentary facies are described in

300-756: The Battle of the North Cape was fought in the Arctic Ocean off this cape, where the German battleship Scharnhorst was eventually sunk by gunfire from the British battleship HMS Duke of York and torpedoes from the Norwegian destroyer HNoMS Stord , and other ships of the British Navy . A road to the North Cape was first built in 1956. As of Q3 2022, the justice system has decided that money will not be charged for parking [on

325-580: The Solothurn Jura ), in which he introduced the "concept of facies" to describe the environments and conditions of the origin of sedimentary rocks based on their petrographic attributes and fossil affiliations. From 1853 he served as a geologist during the construction of rail tunnels through the Jura Mountains. In 1859 he was sent by Eduard Desor to Cette on the Gulf of Lyon in order to investigate

350-492: The midnight sun and views of the Barents Sea to the north. North Cape Hall, a visitor centre , was built in 1988 on the plateau.

However, the neighbouring Knivskjellodden Cape actually extends 1,450 m (4,760 ft) further north. Furthermore, both of these points are situated on an island ( Magerøya ), albeit one connected by road to the mainland. The northernmost point of mainland Europe is located at Cape Nordkinn ( Kinnarodden ) which lies about 5.7 km (3.5 mi) further south and about 70 km (43 mi) to

In 2000, and again in 2011, the Norwegian Ministry of the Environment responded to pressure from interest groups and asked Nordkapps VEL, the company that maintains the site, to reduce the admission fee to the plateau. Nordkapps VEL responded that

The northernmost point of Europe including islands, is hundreds of kilometers further north, either in Russia's Franz Josef Land or Norway's Svalbard archipelago, depending on whether Franz Josef Land is considered to be in Europe or in Asia. The North Cape is the point where the Norwegian Sea , part of
