Lough Bellawaum
Mweelrea (; ) at , is the 26th-highest peak in Ireland on the Arderin scale, and the 34th-highest peak on the Vandeleur-Lynam scale.Mountainviews, (September 2013), "A Guide to Ireland's Mountain Summits: The Vandeleur-Lynams & the Arderins", Collins Books, Cork, Mweelrea is situated near the apex of a "horseshoe-shaped" massif that includes the peaks of Ben Lugmore and Ben Bury, and which is located between Killary Harbour and Doo Lough, in Mayo, Ireland. Mweelrea is the provincial top for Connacht, and is noted for its southeastern cliff lined corries, and its views. The massif is called the Mweelrea Mountains or the Mweelrea Range. Naming Mweelrea is an anglicisation of the , which translates as "bald hill with the smooth top", which describes the profile of the mountain. Geology The geology of what is known as the ''Mweelrea Formation'' is very different from that of the Twelve Bens, on the other side of Killary Harbour. At a summary level, the ''Mweelrea Formation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cirque
A (; from the Latin word ') is an amphitheatre-like valley formed by glacial erosion. Alternative names for this landform are corrie (from Scottish Gaelic , meaning a pot or cauldron) and (; ). A cirque may also be a similarly shaped landform arising from fluvial erosion. The concave shape of a glacial cirque is open on the downhill side, while the cupped section is generally steep. Cliff-like slopes, down which ice and glaciated debris combine and converge, form the three or more higher sides. The floor of the cirque ends up bowl-shaped, as it is the complex convergence zone of combining ice flows from multiple directions and their accompanying rock burdens. Hence, it experiences somewhat greater erosion forces and is most often overdeepened below the level of the cirque's low-side outlet (stage) and its down-slope (backstage) valley. If the cirque is subject to seasonal melting, the floor of the cirque most often forms a tarn (small lake) behind a dam, which marks the down ...

Bundorragha River
Killary Harbour or Killary Fjord () is a fjord or fjard on the west coast of Ireland, in northern Connemara. To its north is County Mayo and the mountains of Mweelrea and Ben Gorm; to its south is County Galway and the Maumturk Mountains. Structure The flooded valley is long, and in the centre over deep; the sea level is higher outside its mouth, as is normal for a fjord.Collins Press, Cork, Ireland - Ireland's Coastline: Exploring its Nature and Heritage - Nairn, Richard, 2007: "the long, narrow fjord of Killary Harbour, which forms the boundary between the counties of Mayo and Galway. ... only a few hundred metres wide. A glacier must have scoured the bottom as it moved towards the sea, taking large volumes of rock and gravel with it. Just outside the entrance, the depth reduces dramatically and there are a number of rocky islands giving a profile that is typical of the fjords of Scandinavia." For nearly half its length, it runs south east from the Atlantic, and then it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Townsland
A townland ( ga, baile fearainn; Ulster-Scots: ''toonlann'') is a small geographical division of land, historically and currently used in Ireland and in the Western Isles in Scotland, typically covering . The townland system is of Gaelic origin, pre-dating the Norman invasion, and most have names of Irish origin. However, some townland names and boundaries come from Norman manors, plantation divisions, or later creations of the Ordnance Survey.Connolly, S. J., ''The Oxford Companion to Irish History, page 577. Oxford University Press, 2002. ''Maxwell, Ian, ''How to Trace Your Irish Ancestors'', page 16. howtobooks, 2009. The total number of inhabited townlands in Ireland was 60,679 in 1911. The total number recognised by the Irish Place Names database as of 2014 was 61,098, including uninhabited townlands, mainly small islands. Background In Ireland a townland is generally the smallest administrative division of land, though a few large townlands are further divided into hu ...

Fjord
In physical geography, a fjord or fiord () is a long, narrow inlet with steep sides or cliffs, created by a glacier. Fjords exist on the coasts of Alaska, Antarctica, British Columbia, Chile, Denmark, Germany, Greenland, the Faroe Islands, Iceland, Ireland, Kamchatka, the Kerguelen Islands, Labrador, Newfoundland, New Zealand, Norway, Novaya Zemlya, Nunavut, Quebec, the Patagonia region of Argentina and Chile, Russia, South Georgia Island, Tasmania, United Kingdom, and Washington state. Norway's coastline is estimated to be long with its nearly 1,200 fjords, but only long excluding the fjords. Formation A true fjord is formed when a glacier cuts a U-shaped valley by ice segregation and abrasion of the surrounding bedrock. According to the standard model, glaciers formed in pre-glacial valleys with a gently sloping valley floor. The work of the glacier then left an overdeepened U-shaped valley that ends abruptly at a valley or trough end. Such valleys are fjords wh ...

Alluvial Fans
An alluvial fan is an accumulation of sediments that fans outwards from a concentrated source of sediments, such as a narrow canyon emerging from an escarpment. They are characteristic of mountainous terrain in arid to semiarid climates, but are also found in more humid environments subject to intense rainfall and in areas of modern glaciation. They range in area from less than to almost . Alluvial fans typically form where flow emerges from a confined channel and is free to spread out and infiltrate the surface. This reduces the carrying capacity of the flow and results in deposition of sediments. The flow can take the form of infrequent debris flows or one or more ephemeral or perennial streams. Alluvial fans are common in the geologic record, such as in the Triassic basins of eastern North America and the New Red Sandstone of south Devon. Such fan deposits likely contain the largest accumulations of gravel in the geologic record. Alluvial fans have also been found on Mar ...

Sandstones
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ordovician
The Ordovician ( ) is a geologic period and System (geology), system, the second of six periods of the Paleozoic Era (geology), Era. The Ordovician spans 41.6 million years from the end of the Cambrian Period million years ago (Mya) to the start of the Silurian Period Mya. The Ordovician, named after the Celtic Britons, Welsh tribe of the Ordovices, was defined by Charles Lapworth in 1879 to resolve a dispute between followers of Adam Sedgwick and Roderick Murchison, who were placing the same Rock (geology), rock beds in North Wales in the Cambrian and Silurian systems, respectively. Lapworth recognized that the fossil fauna in the disputed Stratum, strata were different from those of either the Cambrian or the Silurian systems, and placed them in a system of their own. The Ordovician received international approval in 1960 (forty years after Lapworth's death), when it was adopted as an official period of the Paleozoic Era by the International Union of Geological Sciences, Intern ...
