Gneiss ( / n aɪ s / nice ) is a common and widely distributed type of metamorphic rock . It is formed by high-temperature and high-pressure metamorphic processes acting on formations composed of igneous or sedimentary rocks . This rock is formed under pressures anywhere from 2 to 15 kbar, sometimes even more, and temperatures over 300 °C (572 °F). Gneiss nearly always shows a banded texture characterized by alternating darker and lighter colored bands and without a distinct cleavage .
70-551: Erris is a barony in northwestern County Mayo in Ireland consisting of over 230,452 acres (932.61 km), much of which is mountainous blanket bog. It has extensive sea coasts along its west and north boundaries. The main towns are Belmullet and Bangor Erris . The name Erris derives from the Irish 'Iar Ros' meaning 'western promontory'. The full name is the Iorrais Domnann, after

The area with the most Irish speakers is Ceathrú Thaidhg. There are between 3,500-5,000 native Irish speakers in Erris. Much of inland Erris
210-483: A municipal corporation which had parallel authority with the grand jury; however, each county corporate except Carrickfergus included rural "liberties" outside the municipal boundary. The Municipal Corporations (Ireland) Act 1840 abolished the corporations of Carrickfergus and Galway, while the Counties and Boroughs (Ireland) Act 1840, passed simultaneously, transferred the liberties of the other six counties corporate to
280-615: A barony together with the town, while the liberties on the west bank of the River Bann were attached to the separate half-barony of Coleraine . The lands of the Lordship of Newry , originating with the Cistercians of Newry Abbey and passing to the Earl of Kilmorey , were similarly regularised into a barony of County Down and a civil parish of County Armagh . There were eight counties corporate:

With minor changes in climate and high rainfall levels the land became blanketed by the bog and remains that way to the current day. When present-day turf cutters harvest the bog for fuel, archaeological remains, mainly from the Neolithic and early Bronze Age , which have become buried under

Across inland Erris, the remains of these forests can be seen across the blanket bog landscape in the form of fossilised greying tree stumps which are mainly the remains of ancient Scots pine trees. These become most obvious where there has been harvesting of turf ( peat ) for fuel. The odd petrified bog oak can be found too. During

Some public houses and older provincial hotels bear the name of the barony in which they are located; likewise some clubs of the Gaelic Athletic Association , for example Carbury (County Kildare), Castlerahan , and Kilmurry Ibrickane . Four of the six regional divisions of Cork GAA are named after baronies corresponding to major parts of their respective areas: Carbery , Duhallow , Imokilly , and Muskerry . The final catalogue of baronies numbered 331. A figure of 273
560-487: A large influx of population into Erris where the disinherited native Irish tried to eke a living from very poor quality agricultural land under the tenancy of the landlords and their agents. During the Irish Famine of 1845 - '47 many died in Erris despite the close proximity of the sea, because they could not raise the cash to fund a passage to America. Some 19th- and early 20th-century antiquarians and surveyors visited

In the Norman period most Gaelic chiefs were killed, expelled, or subordinated by the new Norman lord; in the Tudor period, many Gaelic and Hibernicized lords retained their land by pledging allegiance to the Crown under surrender and regrant . Sir John Perrot 's commissioners reported 184 "cantreds, otherwise called hundreds or baronies" in 1589; William Petty reported 252 baronies in 1672. Baronies were sometimes subdivided, and occasionally combined. The parts of
700-484: A local jury picked by the county grand jury from among the barony's highest rate-payers, according to a complicated formula. The baronial presentment sessions were a convoluted process, lacking public confidence and marred by allegations of corruption and favouritism. Special emergency sessions were held during the Famine of the 1840s for the make-work schemes. Several parallel local administrative divisions were formed in
770-400: A specific royal charter granting them borough status similar to English law . These were originally independent of the baronies, which were rural divisions of the "county at large". By the time of Beaufort's 1792 Memoir of Ireland , this was true of fewer towns. Beaufort distinguishes between baronies and "peculiar districts"; the latter encompassing counties corporate and liberties in

Some subdivisions came about when new counties were formed, and the new boundary split a pre-existing barony. In three cases, there are adjacent half-baronies in neighbouring counties with the same name: Rathdown ( Dublin — Wicklow ), Fore ( Meath — Westmeath ), and Ballymoe ( Galway — Roscommon ).

Species of fauna found on Atlantic blanket bog, include smaller varieties such as frogs and insects as well as many bird varieties, not common elsewhere. Several areas of the blanket bog are protected under European legislation such as Special Areas of Conservation , Special Protection Areas (Birds Directive) and Natural Heritage Areas. These include

The finer grained material deforms around the more resistant feldspar grains to produce this texture. Migmatite is a gneiss consisting of two or more distinct rock types, one of which has the appearance of an ordinary gneiss (the mesosome ), and another of which has

Every point in Ireland is in precisely one of the listed divisions. However, the municipal area of the four cities with barony status in 1898 has extended since then into the surrounding baronies. Prior to 1898, the baronies around Dublin City were shrunk according as they ceded land to
1120-518: Is called gneissic banding. The darker bands have relatively more mafic minerals (those containing more magnesium and iron ). The lighter bands contain relatively more felsic minerals (minerals such as feldspar or quartz , which contain more of the lighter elements, such as aluminium , sodium , and potassium ). The banding is developed at high temperature when the rock is more strongly compressed in one direction than in other directions ( nonhydrostatic stress ). The bands develop perpendicular to
1190-449: Is classified as schist, while metamorphic rock devoid of schistosity is called a granofels . Gneisses that are metamorphosed igneous rocks or their equivalent are termed granite gneisses, diorite gneisses, and so forth. Gneiss rocks may also be named after a characteristic component such as garnet gneiss, biotite gneiss, albite gneiss, and so forth. Orthogneiss designates a gneiss derived from an igneous rock , and paragneiss
1260-399: Is covered with blanket bog . A triangle between Ballycroy , Bellacorick and Bangor Erris consists of little else over its surface. Blanket bog, unlike raised bog , grows slowly across the landscape like a blanket covering the ground, due to a continuous supply of water from rainfall, maintaining waterlogged conditions on the ground. The bog is acidic with a pH of between 3.5 and 4.2. This
1330-510: Is one from a sedimentary rock . Both the BGS and the IUGS use gneissose to describe rocks with the texture of gneiss, though gneissic also remains in common use. For example, a gneissose metagranite or a gneissic metagranite both mean a granite that has been metamorphosed and thereby acquired gneissose texture. The minerals in gneiss are arranged into layers that appear as bands in cross section. This
1400-506: Is subjected to extreme temperature and pressure and is composed of alternating layers of sandstone (lighter) and shale (darker), which is metamorphosed into bands of quartzite and mica. Another cause of banding is "metamorphic differentiation", which separates different materials into different layers through chemical reactions, a process not fully understood.

In traditional English and North American usage, a gneiss is a coarse-grained metamorphic rock showing compositional banding ( gneissic banding ) but poorly developed schistosity and indistinct cleavage . In other words, it is a metamorphic rock composed of mineral grains easily seen with the unaided eye, which form obvious compositional layers, but which has only a weak tendency to fracture along these layers.

Erris Head is not served by any road and can only be reached by crossing a number of fields from the hamlet of Glenlara where the road ends. Along the coast there are several uninhabited islands . These include the Inishkea Islands , Inishglora , Duvillaun , the Stags of Broadhaven Bay and other smaller islands. Erris, in common with most of inland Ireland, became covered in extensive native woodland

It is an important area for bird watchers as the largely treeless landscape allows relatively easy access for birdwatching . Brent geese overwinter here feeding along
1820-563: The Irish House of Commons , the election was held in the county town , with a separate polling booth for electors resident in each barony or half-baroiny. The single-seat divisions into which the Redistribution of Seats Act 1885 split most Irish county constituencies were defined largely or exclusively in terms of the baronies which they comprised; however, in some cases a barony was split parish by parish between two divisions. The 1891 census
1890-468: The Neolithic period, starting about 6,000 years ago, the first people living in Ireland whose ancestors had hunted and gathered along the coastlines of Erris from about 9,000 years ago, began to cut down the forestry to clear land for growing crops and grazing livestock. Because the underlying rock type was ancient and heavily weathered schists the soil was thin and easily eroded by inclement weather. After
1960-464: The counties of England were divided. Baronies were created during the Tudor reconquest of Ireland , replacing the earlier cantreds formed after the original Norman invasion . Some early baronies were later subdivided into half baronies with the same standing as full baronies. Baronies were mainly cadastral rather than administrative units. They acquired modest local taxation and spending functions in

These were excluded from the enclosing "county-at-large" and exercised at a single level the functions which elsewhere were split between county and barony level. Thus, they had "baronial presentment sessions" although they were not strictly speaking baronies. Each such city or town also had

The final catalogue of baronies numbered 331, with an average area of 255 km (98 sq mi; 63,000 acres); therefore, each county was divided, on average, into 10 or 11 baronies. The island of Ireland
2170-730: The 19th century, when qualifiers "Upper"/"Lower"(/"Middle"), "North"/"South", or "East/"West" were used for the half-baronies. The main basis for this subdivision was the Grand Jury (Ireland) Act, 1836 , which empowered a county's grand jury to divide baronies of at least 45,000 acres (18,000 ha) and unite baronies totalling at most 40,000 acres (16,000 ha). An 1837 act relaxed these restrictions for County Fermanagh , where many baronies were split by Lough Erne . The baronies of Iveagh, Muskerry, and Connello were each subdivided twice: Upper and Lower Iveagh each have Upper and Lower Halves; East and West Muskerry each have East and West Divisions;

Erris is a popular location for many types of watersports ranging through fishing , sailing , surfing , swimming, wind surfing , kiteboarding and kite surfing . There are a number of walking trails in Erris. These include cliff walks above the Atlantic at Broadhaven Bay along Benwee Head , Glinsk and the North Mayo coastline, as well as mountain walks across uninhabited natural wilderness , and long distance walks such as

Per the polar decomposition theorem , the deformation produced by such shearing force is equivalent to rotation of the rock combined with shortening in one direction and extension in another. Some banding is formed from original rock material (protolith) that

For example, a 1994 statutory instrument extended the boundary of the Barony of Arklow , along with the boundaries of the county ( Wicklow ), the district electoral division (Arklow Rural), the civil parish ( Arklow ), and the townlands (Rock Big, Rock Little, and Money Big). The Local Government (Ireland) Act also caused a number of county boundaries to be modified, with
3290-402: The direction of greatest compression, also called the shortening direction, as platy minerals are rotated or recrystallized into parallel layers. A common cause of nonhydrodynamic stress is the subjection of the protolith (the original rock material that undergoes metamorphism) to extreme shearing force, a sliding force similar to the pushing of the top of a deck of cards in one direction, and

Many different varieties of rock can be metamorphosed to gneiss, so geologists are careful to add descriptions of the color and mineral composition to the name of any gneiss, such as garnet-biotite paragneiss or grayish-pink orthogneiss . Continental shields are regions of exposed ancient rock that make up

In certain counties after the Cromwellian reconquest , Adventurers got lands in half the baronies, with soldiers in the other half. The Irish who had forfeited their lands in those regions were resettled in Connacht and Clare , with each county of origin assigned to particular destination baronies. William Petty 's Down Survey of 1655–6 collected statistics and produced maps at barony level to assist

Both before and after 1898, where a statute presupposed that a county was divided into baronies, judges sometimes construed it by assuming that each county corporate constituted a single barony. The various Plantations of Ireland were organised largely by barony. Different categories of English and Scottish settlers were planted in particular baronies in
4130-594: The reorganisation. Acts of 1787 and 1792 allowed the Lord Lieutenant of Ireland to appoint a constable for each barony, and the county grand jury to appoint up to 16 sub-constables. These powers were seldom used and the constables had few powers; they were usually older men nicknamed "old Barnys", with the archetypal "old Barny McKeown". They were superseded by the Royal Irish Constabulary . The cess to pay for roads, bridges, and other public works

This can cause confusion to genealogy researchers, who may be unable to find an area referred to as being in a particular county in 19th century sources in the modern county. Most markedly, the entire territory of the small barony of Kilculliheen was moved from County Waterford to County Kilkenny . Likewise in 1976, when suburbs of Drogheda were transferred from County Meath to County Louth, barony boundaries were not adjusted. The marginal relevance of baronies means many people have no idea which barony they live in. However, some remain

4550-850: The term has been more widely applied to any coarse, mica -poor, high-grade metamorphic rock. The British Geological Survey (BGS) and the International Union of Geological Sciences (IUGS) both use gneiss as a broad textural category for medium- to coarse-grained metamorphic rock that shows poorly developed schistosity, with compositional layering over 5 millimeters (0.20 in) thick and tending to split into plates over 1 centimeter (0.39 in) thick. Neither definition depends on composition or origin, though rocks poor in platy minerals are more likely to produce gneissose texture. Gneissose rocks thus are largely recrystallized but do not carry large quantities of micas, chlorite or other platy minerals. Metamorphic rock showing stronger schistosity

"Presentment sessions ", where petitioners applied for funding for such works, were originally held as part of the county assizes , though the costs were paid from the barony cess if the work was of local benefit only.

From 1819, significantly modified in 1836, baronial presentment sessions were held for these purposes, with

These councils had power to levy rates and build public works, and

A townland might be an exclave of a parish, and potentially of its barony; under the Valuation of Lands (Ireland) Act 1836 , detached parts of baronies were annexed to an adjacent barony, but not so for parishes. The rationalisation of small ecclesiastical parishes into larger benefices sometimes entailed merging the corresponding civil parishes, which might thus cross barony (and county) boundaries. Many towns had
