Republic Of Ireland
Ireland ( ga, Éire ), also known as the Republic of Ireland (), is a country in north-western Europe consisting of 26 of the 32 counties of the island of Ireland. The capital and largest city is Dublin, on the eastern side of the island. Around 2.1 million of the country's population of 5.13 million people resides in the Greater Dublin Area. The sovereign state shares its only land border with Northern Ireland, which is part of the United Kingdom. It is otherwise surrounded by the Atlantic Ocean, with the Celtic Sea to the south, St George's Channel to the south-east, and the Irish Sea to the east. It is a unitary, parliamentary republic. The legislature, the , consists of a lower house, ; an upper house, ; and an elected President () who serves as the largely ceremonial head of state, but with some important powers and duties. The head of government is the (Prime Minister, literally 'Chief', a title not used in English), who is elected by the Dáil and appointed by ...

Arête
An arête ( ) is a narrow ridge of rock which separates two valleys. It is typically formed when two glaciers erode parallel U-shaped valleys. Arêtes can also form when two glacial cirques erode headwards towards one another, although frequently this results in a saddle-shaped pass, called a col. The edge is then sharpened by freeze-thaw weathering, and the slope on either side of the arête steepened through mass wasting Mass wasting, also known as mass movement, is a general term for the movement of rock or soil down slopes under the force of gravity. It differs from other processes of erosion in that the debris transported by mass wasting is not entrained in ... events and the erosion of exposed, unstable rock. The word ''arête'' () is actually French for "edge" or "ridge"; similar features in the Alps are often described with the German language, German equivalent term ''Grat''. Where three or more cirques meet, a pyramidal peak is created. Cleaver A ''cleaver' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maolán Buí
Maolán Buí (Irish for "yellow/golden round knoll"), also known by the name Bearna Rua, at high, is the fifth-highest peak in Ireland on the Arderin list, or the sixth-highest peak in Ireland according to the Vandeleur-Lynam list. Maolán Buí is also known for its narrow north-west spur, called ''The Bone''. It is part of the MacGillycuddy's Reeks in Kerry. Geography Maolán Buí is in the eastern part of the MacGillycuddy's Reeks in County Kerry, Ireland's highest mountain range. The peak lies on a ridge between Cnoc na Péiste (to the northeast) and Cnoc an Chuillinn (to the southwest), which are themselves part of the larger eastern ridge of the Reeks, which includes The Big Gun and finishes at its far eastern end with Cruach Mhór . A narrow north-west spur of Maolán Buí called ''The Bone'', not to be confused with the nearby peak that sits on the ''Beenkeragh Ridge'', The Bones , is regarded as a safe ''escape route'' from the eastern section of the ma ...

Cnoc An Chuillinn
Cnoc an Chuillinn (Irish for "hill of the steep slope"), at , is the sixth-highest peak in Ireland on the Arderin list and the seventh-highest peak in Ireland on the Vandeleur-Lynam list. The name is sometimes incorrectly anglicised to Knockacullion, which is a name used for peaks and townlands in other parts of Ireland. Cnoc an Chuillinn is part of the MacGillycuddy's Reeks range in County Kerry. Geography Cnoc an Chuillinn lies in the eastern section of the MacGillycuddy's Reeks, Ireland's highest mountain range. It is at the start of a high ridge section that, moving eastwards, includes Cnoc an Chuillinn East Top () (a subsidiary summit of Cnoc an Chuillinn, but which is itself a Vandeleur-Lynam), Maolán Buí (), Cnoc na Péiste (), The Big Gun () and finishes with Cruach Mhór (). Between Cnoc an Chuillinn, and Cnoc an Chuillinn East Top, lies a major south-east spur to the less frequently climbed, Brassel Mountain (), which descends steeply into the Black Valley ...

Eagle's Nest, Kerry
Carrauntoohil or Carrauntoohill ( ; ga, Corrán Tuathail , meaning "Tuathal's sickle") is the highest mountain in Ireland at . It is on the Iveragh Peninsula in County Kerry, close to the centre of Ireland's highest mountain range, MacGillycuddy's Reeks. Carrauntoohil is composed mainly of sandstone, whose glaciation produced distinctive features on the mountain such as the Eagle's Nest corrie and some deep gullies and sharp arêtes in its east and northeastern faces that are popular with rock and winter climbers. As Ireland's highest mountain, Carrauntoohil is popular with mountain walkers, who most commonly ascend via the Devil's Ladder route; however, Carrauntoohil is also climbed as part of longer mountain walking routes in the MacGillycuddy's Reeks range, including the Coomloughra Horseshoe or the MacGillycuddy's Reeks Ridge Walk of the entire mountain range. Carrauntoohil, and most of the range, is held in private ownership and is not part of any Irish national park; h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conglomerate Rock
Conglomerate () is a clastic sedimentary rock that is composed of a substantial fraction of rounded to subangular gravel-size clasts. A conglomerate typically contains a matrix of finer-grained sediments, such as sand, silt, or clay, which fills the interstices between the clasts. The clasts and matrix are typically cemented by calcium carbonate, iron oxide, silica, or hardened clay. Conglomerates form by the consolidation and lithification of gravel. They can be found in sedimentary rock sequences of all ages but probably make up less than 1 percent by weight of all sedimentary rocks. In terms of origin and depositional mechanisms, they are closely related to sandstones and exhibit many of the same types of sedimentary structures, e.g., tabular and trough cross-bedding and graded bedding.Boggs, S. (2006) ''Principles of Sedimentology and Stratigraphy.'', 2nd ed. Prentice Hall, New York. 662 pp. Friedman, G.M. (2003) ''Classification of sediments and sedimentary rocks.'' In Ger ...

Siltstones
Siltstone, also known as aleurolite, is a clastic sedimentary rock that is composed mostly of silt. It is a form of mudrock with a low clay mineral content, which can be distinguished from shale by its lack of fissility.Blatt ''et al.'' 1980, pp.381-382 Although its permeability and porosity is relatively low, siltstone is sometimes a tight gas reservoir rock, an unconventional reservoir for natural gas that requires hydraulic fracturing for economic gas production. Siltstone was prized in ancient Egypt for manufacturing statuary and cosmetic palettes. The siltstone quarried at Wadi Hammamat was a hard, fine-grained siltstone that resisted flaking and was almost ideal for such uses. Description There is not complete agreement on the definition of siltstone. One definition is that siltstone is mudrock (clastic sedimentary rock containing at least 50% clay and silt) in which at least 2/3 of the clay and silt fraction is composed of silt-sized particles. Silt is defined as gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mudstones
Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. Mudstone is distinguished from ''shale'' by its lack of fissility (parallel layering).Blatt, H., and R.J. Tracy, 1996, ''Petrology.'' New York, New York, W. H. Freeman, 2nd ed, 529 pp. The term ''mudstone'' is also used to describe carbonate rocks (limestone or dolomite) that are composed predominantly of carbonate mud. However, in most contexts, the term refers to siliciclastic mudstone, composed mostly of silicate minerals. The NASA Curiosity rover has found deposits of mudstone on Mars that contain organic substances such as propane, benzene and toluene. Definition There is not a single definition of mudstone that has gained general acceptance,Boggs 2006, p.143 though there is wide agreement that mudstones are fine-grained sedimentary rocks, composed mostly of silicate grains with a grain size less than . Individual grains this size are too small to be distingui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quartz
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The atoms are linked in a continuous framework of SiO4 silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar. Quartz exists in two forms, the normal α-quartz and the high-temperature β-quartz, both of which are chiral. The transformation from α-quartz to β-quartz takes place abruptly at . Since the transformation is accompanied by a significant change in volume, it can easily induce microfracturing of ceramics or rocks passing through this temperature threshold. There are many different varieties of quartz, several of which are classified as gemstones. Since antiquity, varieties of quartz have been the most commonly used minerals in the making of jewelry and hardstone carvings, especially in Eurasia. Quartz is the mineral defining the val ...

County Cork
County Cork ( ga, Contae Chorcaí) is the largest and the southernmost county of Ireland, named after the city of Cork, the state's second-largest city. It is in the province of Munster and the Southern Region. Its largest market towns are Mallow, Macroom, Midleton, and Skibbereen. the county had a population of 581,231, making it the third- most populous county in Ireland. Cork County Council is the local authority for the county, while Cork City Council governs the city of Cork and its environs. Notable Corkonians include Michael Collins, Jack Lynch, Roy Keane, Sonia O'Sullivan and Cillian Murphy. Cork borders four other counties: Kerry to the west, Limerick to the north, Tipperary to the north-east and Waterford to the east. The county contains a section of the Golden Vale pastureland that stretches from Kanturk in the north to Allihies in the south. The south-west region, including West Cork, is one of Ireland's main tourist destinations, known for its rugged coast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Old Red Sandstone
The Old Red Sandstone is an assemblage of rocks in the North Atlantic region largely of Devonian age. It extends in the east across Great Britain, Ireland and Norway, and in the west along the northeastern seaboard of North America. It also extends northwards into Greenland and Svalbard. These areas were a part of the ancient continent of Euramerica, Euramerica/Laurussia. In Britain it is a lithostratigraphy, lithostratigraphic unit (a sequence of rock strata) to which Stratigraphy, stratigraphers accord Geological unit#Lithostratigraphic units, supergroup status and which is of considerable importance to early paleontology. For convenience the short version of the term, ORS is often used in literature on the subject. The term was coined to distinguish the sequence from the younger New Red Sandstone which also occurs widely throughout Britain. Sedimentology The Old Red Sandstone describes a suite of sedimentary rocks deposited in a variety of environments during the Devonian ...
