North-West Highlands
The Northwest Highlands are located in the northern third of Scotland that is separated from the Grampian Mountains by the Great Glen (Glen More). The region comprises Wester Ross, Assynt, Sutherland and part of Caithness. The Caledonian Canal, which extends from Loch Linnhe in the south-west, via Loch Ness to the Moray Firth in the north-east splits this area from the rest of the country. The city of Inverness and the town of Fort William serve as gateways to the region from the south. Geology The geology of the Highlands is complex. Along the western coastal margin it is characterised by Lewisian gneiss, the oldest rock in Scotland. Liathach, Beinn Alligin, Suilven, Cùl Mòr, Cùl Beag, and Quinag are just some of the impressive rock islands of the significantly younger rich brown-coloured Torridonian sandstone which rests on the gneiss. Some of the peaks, such as Beinn Eighe and Canisp, are topped with later light grey or white Cambrian quartzite. Cambro-Ordovician limestone ...

Scotland
Scotland (, ) is a country that is part of the United Kingdom. Covering the northern third of the island of Great Britain, mainland Scotland has a border with England to the southeast and is otherwise surrounded by the Atlantic Ocean to the north and west, the North Sea to the northeast and east, and the Irish Sea to the south. It also contains more than 790 islands, principally in the archipelagos of the Hebrides and the Northern Isles. Most of the population, including the capital Edinburgh, is concentrated in the Central Belt—the plain between the Scottish Highlands and the Southern Uplands—in the Scottish Lowlands. Scotland is divided into 32 administrative subdivisions or local authorities, known as council areas. Glasgow City is the largest council area in terms of population, with Highland being the largest in terms of area. Limited self-governing power, covering matters such as education, social services and roads and transportation, is devolved from the Scott ...

Beinn Alligin
Beinn Alligin ( gd, Beinn Àilleagan) is one of the classic mountains of the Torridon region of Scotland, lying to the north of Loch Torridon, in the Highlands. The name Beinn Alligin is from the Scottish Gaelic, meaning ''Jewelled Hill''. The mountain has two peaks of Munro status: Tom na Gruagaich () to the south, and Sgùrr Mhòr at to the north. One of the most prominent features of Beinn Alligin is a great cleft known as Eag Dhubh na h-Eigheachd (''black gash of the wailing'') or Leum na Caillich, which cuts into the ridge south of the summit. It is the scar of the most spectacular rockslide or rock avalanche in Britain, which runs out into the corrie of Toll a' Mhadaidh Mor. It occurred around 3750 years ago and is around 3.5 million cubic metres in volume. According to local folklore shepherds on the mountain would hear cries from the gash; those who investigated the source of these cries would inevitably fall to their deaths. Beinn Alligin lies on the National Tru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moine Supergroup
The Moine Supergroup is a sequence of Neoproterozoic metamorphic rocks that form the dominant outcrop of the Scottish Highlands between the Moine Thrust Belt to the northwest and the Great Glen Fault to the southeast. The sequence is metasedimentary in nature and was metamorphosed and deformed in a series of tectonic events during the Late Proterozoic and Early Paleozoic. It takes its name from ''A' Mhòine'', a peat bog in northern Sutherland. Distribution The main outcrop of the Moine series lies northwest of the Great Glen Fault, structurally above the Moine Thrust to the west forming what is known as the Northern Highlands Terrane. A smaller area of similar rocks that are correlated with these, outcrop within the 'Grampian Terrane' to the southeast of the Great Glen. Moinian rocks are also recognised on Mull, Orkney and Shetland. Stratigraphy The Moine Supergroup has been subdivided into different groups or divisions. The relationship between individual groups in terms of ag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skye
The Isle of Skye, or simply Skye (; gd, An t-Eilean Sgitheanach or ; sco, Isle o Skye), is the largest and northernmost of the major islands in the Inner Hebrides of Scotland. The island's peninsulas radiate from a mountainous hub dominated by the Cuillin, the rocky slopes of which provide some of the most dramatic mountain scenery in the country. Slesser (1981) p. 19. Although has been suggested to describe a winged shape, no definitive agreement exists as to the name's origins. The island has been occupied since the Mesolithic period, and over its history has been occupied at various times by Celtic tribes including the Picts and the Gaels, Scandinavian Vikings, and most notably the powerful integrated Norse-Gaels clans of MacLeod and MacDonald. The island was considered to be under Norwegian suzerainty until the 1266 Treaty of Perth, which transferred control over to Scotland. The 18th-century Jacobite risings led to the breaking-up of the clan system and later clearanc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Durness
Durness ( gd, Diùranais) is a village and civil parish in the north-west Highlands of Scotland. It lies on the north coast of the country in the traditional county of Sutherland, around north of Inverness. The area is remote, and the parish is huge and sparsely populated, covering an area from east of Loch Eriboll to Cape Wrath, the most north-westerly point of the Scottish mainland. The population is dispersed and includes a number of townships including Kempie, Eriboll, Laid, , Sangobeg, Leirinmore, Smoo, Sangomore, Durine, Balnakeil and Keoldale. Etymology The name could be Norse "Dyrnes", meaning "deer/animal headland". No one knows for sure where the name derives; it has variously been translated as from "Dorainn nis" tempest point, or "Dhu thir nis" the point of the black land; or from the Norse for deerpoint. Or even from the main village "Durine" which would translate as "Dubh Rinn" the black (or fertile) promontory, with the Norse "ness" tacked onto an existing Ga ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...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 ...

Quartzite
Quartzite is a hard, non- foliated metamorphic rock which was originally pure quartz sandstone.Essentials of Geology, 3rd Edition, Stephen Marshak, p 182 Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of hematite. Other colors, such as yellow, green, blue and orange, are due to other minerals. The term ''quartzite'' is also sometimes used for very hard but unmetamorphosed sandstones that are composed of quartz grains thoroughly cemented with additional quartz. Such sedimentary rock has come to be described as orthoquartzite to distinguish it from metamorphic quartzite, which is sometimes called metaquartzite to emphasize its metamorphic origins. Quartzite is very resistant to chemical weathering and often forms ridges and resistant hilltops. The nearly pure silica conte ...

Canisp
Canisp (Scottish Gaelic: ''Canasp'') is a mountain in the far north west of Scotland. It is situated in the parish of Assynt, in the county of Sutherland, north of the town of Ullapool. Canisp reaches a height of and qualifies as a Corbett and Marilyn hill. The mountain's name translates from the Old Norse language as ''“White Mountain”''. Geography and geology Canisp is an isolated mountain that stands in the Glencanisp Forest, a large rock and water wilderness. It has a topographic prominence of . Canisp has little vegetation, even on its lower slopes large areas of Gneiss (one of the oldest rocks in the world) are visible on the surface. Canisp stands in a geologically important area. It is part of the Moine Thrust Belt and is typical of many of the Assynt hills in that it rises from a base of Lewisian Gneiss and is composed of Torridonian sandstone capped by Cambrian quartzite giving the hill a distinctive light grey crown.Canisp was formed when surrounding rocks ...

Beinn Eighe
Beinn Eighe () is a mountain massif in the Torridon area of Wester Ross in the Northwest Highlands of Scotland. Lying south of Loch Maree, it forms a long ridge with many spurs and summits, two of which are classified as Munros: Ruadh-stac Mòr at and Spidean Coire nan Clach at . Unlike most other hills in the area it has a cap of Cambrian basal quartzite which gives the peaks of Beinn Eighe a distinctive light colour. Its complex topography has made it popular with both hillwalkers and climbers and the national nature reserve on its northern side makes it an accessible mountain for all visitors. Geography Located between Loch Maree and Glen Torridon on the west coast of Scotland, Beinn Eighe is a complex mountain. The main ridge runs on a line extending from close to the village of Kinlochewe in the north-east to the narrow glen of the Coire Dubh Mòr, which separates it from the neighbouring mountain of Liathach to the south-west. The slopes into Glen Torrido ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torridonian Sandstone
In geology, the term Torridonian is the informal name for the Torridonian Group, a series of Mesoproterozoic to Neoproterozoic arenaceous and argillaceous sedimentary rocks, which occur extensively in the Northwest Highlands of Scotland. The strata of the Torridonian Group are particularly well exposed in the district of upper Loch Torridon, a circumstance which suggested the name Torridon Sandstone, first applied to these rocks by James Nicol. Stratigraphically, they lie unconformably on gneisses of the Lewisian complex and their outcrop extent is restricted to the Hebridean Terrane. Rock type The rocks are mainly red and brown sandstones, arkoses and shales with coarse conglomerates locally at the base. Some of the materials of these rocks were derived from the underlying Lewisian gneiss, upon the uneven surface of which they rest, but the bulk of the material was obtained from rocks that are nowhere now exposed. Upon this ancient denuded land surface the Torridonian strat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
