Shiants
The Shiant Islands (; gd, Na h-Eileanan Mòra or ) or Shiant Isles are a privately owned island group in the Minch, east of Harris in the Outer Hebrides of Scotland. They are southeast of the Isle of Lewis.Keay, J. & Keay, J. (1994) ''Collins Encyclopaedia of Scotland''. London. HarperCollins. Etymology The name ''Shiant'' is from the Scottish Gaelic , which means the "charmed", "holy" or "enchanted isles". The group is also known as , "the big isles". The main islands are Garbh Eilean ("rough island") and Eilean an Taighe ("house island"), which are joined by a narrow isthmus, and Eilean Mhuire ("island of the Virgin Mary") to the east. Eilean an Taighe was called ''Eilean na Cille'' ("island of the church") prior to the 19th century.Haswell-Smith (2004) pp. 275-76 A 17th-century chart by John Adair and several other 18th-century charts call Garbh Eilean ''Nunaltins Isle'', Eilean Mhuire ''St Marys Isle'' and Eilean an Taighe ''St Columbs Isle''.

Garbh Eilean, Shiant Islands
Garbh Eilean (Scottish Gaelic ''Rough Isle'') is one of the Shiant Islands at the south end of the Minch on the west coast of Scotland. Geology In geological terms, these islands essentially represent an extension of the Trotternish peninsula of Skye. The rocks are volcanic, and at 60 Ma, very young by Hebridean standards. Dolerite columns on the north side of Garbh Eilean are over tall and about across. Similar to those at Staffa and the Giant's Causeway, they were formed by the slow cooling of volcanic rocks deep underground. Intrusion sills show a progression in their chemical compositions, from olivine-rich rocks at the base to rocks with very little or no olivine at the top. The sills are thought to have formed by crystal settling. Recent study has suggested that at least one of the sills represents a multiple intrusion. In some places the basalt is overlain by Jurassic mudstone, which weathers to form much more fertile soil than elsewhere in the Western Isles. ...

Eilean An Taighe
:''"Eilean an Taighe", or "Eilean Taigh" is a fairly common island name'' Eilean an T(a)ighe, meaning "House Island" (lit. "Island of the House"), is one of the Shiant Islands. It is joined to Garbh Eilean by an isthmus, so they each form part of what is actually a single island. History Before the 1820s, the island was called ''Eilean na Cille'' ("church island"),Haswell-Smith (2004) pp. 275-76. and there is evidence of a church, possibly dedicated to the Virgin Mary, near the site of the present cottage.Haswell-Smith (2004) pp. 277-78. Eilean Mhuire, one of the other islands in the Shiants, also takes its name from Mary. In the mid-18th century, 40 people were living there, but by 1770 they had all left. In the 1820s a shepherd and his wife were resident, but, by 1842, they too had gone. From 1862 to 1901, another shepherd, Donald Campbell, and his wife and two daughters lived there. The daughters, Mòr and Catriona, were apparently very beautiful, and attracted the attenti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Isle Of Lewis
The Isle of Lewis ( gd, Eilean Leòdhais) or simply Lewis ( gd, Leòdhas, ) is the northern part of Lewis and Harris, the largest island of the Western Isles or Outer Hebrides archipelago in Scotland. The two parts are frequently referred to as if they were separate islands. The total area of Lewis is . Lewis is, in general, the lower-lying part of the island: the other part, Harris, is more mountainous. Due to its larger area and flatter, more fertile land, Lewis contains three-quarters of the population of the Western Isles, and the largest settlement, Stornoway. The island's diverse habitats are home to an assortment of flora and fauna, such as the golden eagle, red deer and seal, and are recognised in a number of conservation areas. Lewis has a Presbyterian tradition and a rich history. It was once part of the Norse Kingdom of the Isles. Today, life is very different from elsewhere in Scotland, with Sabbath observance, the Scottish Gaelic language and peat cutting retainin ...

Cave On Garbh Eilean, Shiant Isles - Geograph
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorgani ...

Fractional Crystallization (geology)
Fractional crystallization, or crystal fractionation, is one of the most important geochemical and physical processes operating within crust and mantle of a rocky planetary body, such as the Earth. It is important in the formation of igneous rocks because it is one of the main processes of magmatic differentiation. Fractional crystallization is also important in the formation of sedimentary evaporite rocks. Igneous rocks Fractional crystallization is the removal and segregation from a melt of mineral precipitates; except in special cases, removal of the crystals changes the composition of the magma. In essence, fractional crystallization is the removal of early formed crystals from an originally homogeneous magma (for example, by gravity settling) so that these crystals are prevented from further reaction with the residual melt. The composition of the remaining melt becomes relatively depleted in some components and enriched in others, resulting in the precipitation of a sequen ...

Scottish Natural Heritage
NatureScot ( gd, NàdarAlba), which was formerly known as Scottish Natural Heritage, is an executive non-departmental public body of the Scottish Government responsible for the country's natural heritage, especially its natural, genetic and scenic diversity. It advises the Scottish Government on nature conservation, and acts as a government agent in the delivery of conservation designations, i.e. national nature reserves, local nature reserves, national parks, Sites of Special Scientific Interest (SSSIs), Special Areas of Conservation, Special Protection Areas and the national scenic areas. It receives annual funding from the Government in the form of Grant in Aid to deliver Government priorities for the natural heritage. NatureScot is the Scottish Government's adviser on all aspects of nature, wildlife management and landscape across Scotland, and also helps the Scottish Government meet its responsibilities under European environmental laws, particularly in relation to th ...

Basalt
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...

Jurassic
The Jurassic ( ) is a Geological period, geologic period and System (stratigraphy), stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of the Mesozoic, Mesozoic Era and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic magmatic province, Central Atlantic Magmatic Province. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread Anoxic event, oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar, Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Donald Monro (Dean)
Donald Monro (or Munro) ( fl. 1526–1574) was a Scottish clergyman, who wrote an early and historically valuable description of the Hebrides and other Scottish islands and enjoyed the honorific title of "Dean of the Isles". Origins Donald Monro was born early in the 16th century, the eldest of the six sons of Alexander Munro of Kiltearn, by Janet, daughter of Farquhar Maclean of Dochgarroch. His father was a grandson of George Munro, 10th Baron of Foulis (Chief of the Clan Munro)Alexander Ross, ''The Reverend Donald Munro, M.A., High Dean of the Isles'', in The Celtic Magazine (volume 9, 1884), at pages 142 to 144. and his maternal grandfather was Farquhar MacLean of Dochgarroch, (''Fearchar Mac Eachainn'') Bishop of the Isles from 1529 to 1544.MacLeod (2004) p. 23 On Farquhar's resignation the bishopric passed to his son, and Donald Monro's uncle, Roderick MacLean (''Ruaidhri Mac Gill-Eathain''). Career Monro became the vicar of Snizort and Raasay in 1526MacLeod (2004) p. 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sill (geology)
In geology, a sill is a tabular sheet intrusion that has intruded between older layers of sedimentary rock, beds of volcanic lava or tuff, or along the direction of foliation in metamorphic rock. A ''sill'' is a ''concordant intrusive sheet'', meaning that a sill does not cut across preexisting rock beds. Stacking of sills builds a sill complex . and a large magma chamber at high magma flux. In contrast, a dike is a discordant intrusive sheet, which does cut across older rocks. Sills are fed by dikes, except in unusual locations where they form in nearly vertical beds attached directly to a magma source. The rocks must be brittle and fracture to create the planes along which the magma intrudes the parent rock bodies, whether this occurs along preexisting planes between sedimentary or volcanic beds or weakened planes related to foliation in metamorphic rock. These planes or weakened areas allow the intrusion of a thin sheet-like body of magma paralleling the existing bedding pla ...
