Scarba
Scarba () is an island, in Argyll and Bute, Scotland, just north of the much larger island of Jura. The island has not been permanently inhabited since the 1960s. Until his death in 2013 it was owned by Richard Hill, 7th Baron Sandys; its owner now is Shane Cadzow who farms Luing cattle on the nearby island of Luing and grazes some of the cattle on Scarba. Kilmory Lodge is used seasonally as a shooting lodge, the island having a flourishing herd of red deer. The island's name is from the Norse and may mean "sharp, stony, hilly terrain" or "cormorant island".Mac an Tàilleir (2003) p. 104 Description Scarba is not served by any public ferries, but access from Craobh Haven or Crinan Harbour is possible by arrangement with local boatmen. The rough summit ridge can be accessed from the harbour at the north end, from where a vehicle track leads up past Kilmory Lodge to a height of about 200 metres. After that, there are no paths or well defined routes, and the terrain b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jura, Scotland
Jura ( ; ) is an island in the Inner Hebrides of Scotland, adjacent to and northeast of Islay. With an area of , and 196 inhabitants recorded in the 2011 census, Jura is more sparsely populated than Islay, and is one of the least densely populated islands of Scotland: in a list of the islands of Scotland ranked by size, Jura comes eighth, whereas by population it comes 31st. The island is mountainous, bare and largely infertile, covered by extensive areas of blanket bog. The main settlement is the east coast village of Craighouse, on the Sound of Jura. The Jura distillery, producing Isle of Jura single malt whisky, is in the village, as is the island's rum distillery which opened in 2021. Craighouse also houses the island's shop, church, primary school, the Jura hotel and bar, a gallery, craft shop, tearoom and the community run petrol pumps. North of Craighouse are a number of other small settlements on or near the east coast: Keils, Knockrome, Ardfernal, Lagg, Jura, Lagg, Tarb ...

Marilyn (hill)
This is a list of Marilyn hills and mountains in the United Kingdom, Republic of Ireland, Ireland and surrounding islands and Stack (geology), sea stacks. Lists of mountains and hills in the British Isles#Marilyns, Marilyns are defined as peaks with a topographic prominence, prominence of or more, regardless of height or any other merit (e.g. topographic isolation, as used in Lists of mountains and hills in the British Isles#Munros, Munros). Thus, Marilyns can be mountains, with a height above , or relatively small hills. there were 2,010 recorded Marilyns. Definition The Marilyn classification was created by Alan Dawson in his 1992 book ''The Relative Hills of Britain''. The name Marilyn was coined by Dawson as a punning contrast to the ''Munro'' classification of Scottish mountains above , but which has no explicit prominence threshold, being homophone, homophonous with (Marilyn) ''Marilyn Monroe, Monroe''. The list of Marilyns was extended to Ireland by Clem Clements. Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inner Hebrides
The Inner Hebrides ( ; ) is an archipelago off the west coast of mainland Scotland, to the south east of the Outer Hebrides. Together these two island chains form the Hebrides, which experience a mild oceanic climate. The Inner Hebrides comprise 35 inhabited islands as well as 44 uninhabited islands with an area greater than . Skye, Isle of Mull, Mull, and Islay are the three largest, and also have the highest populations. The main commercial activities are tourism, crofting, fishing and Scotch whisky, whisky distilling. In modern times the Inner Hebrides have formed part of two separate local government jurisdictions, one to the north and the other to the south. Together, the islands have an area of about , and had a population of 18,948 in 2011. The population density is therefore about . There are various important prehistoric structures, many of which pre-date the first written references to the islands by Classical antiquity, Roman and Greek authors. In the historic period ...

Argyll And Bute
Argyll and Bute (; , ) is one of 32 unitary authority, unitary council areas of Scotland, council areas in Scotland and a lieutenancy areas of Scotland, lieutenancy area. The current lord-lieutenant for Argyll and Bute is Jane Margaret MacLeod (14 July 2020). The administrative centre for the council area is in Lochgilphead at Kilmory Castle, a 19th-century Gothic Revival building and estate. The current council leader is Councillor Jim Lynch. Argyll and Bute covers the second-largest administrative area of any Scottish council. The council area adjoins those of Highland (council area), Highland, Perth and Kinross, Stirling (council area), Stirling and West Dunbartonshire. History The County of County of Bute, Bute and the County of Argyll were two of the shires of Scotland, historic counties of Scotland. They were both "''shires''" (context; the area controlled by a sheriff principal, sheriff) in the Middle Ages. From 1890 until 1975 both counties had individual separate ele ...

Luing Cattle
Luing cattle (pronounced ''ling cattle'') are a beef breed developed on the island of Luing in the Inner Hebrides of Scotland by the Cadzow brothers in 1947. It was formed by first crossbreeding Beef Shorthorn with Highland cattle and then breeding the resulting progeny with Beef Shorthorns to produce an animal three quarters Beef Shorthorn, one quarter Highland. The breed of red-brown cattle are moderately sized and extremely hardy. The intent was to produce a good beef cow with the ability to raise a calf under adverse weather conditions. It was officially recognised as a breed by the British government in 1965. The breed is still farmed today, mainly in Scotland but also in other areas of the world. History Luings were first created by the Cadzow brothers; Ralph, Denis and Shane, in 1947. They crossbred two types of cattle to produce the Luing; the Highland as the heifer and the Beef Shorthorn as the bull, and were the first new breed of cattle developed in Britain in over ...

Argyll Group
The Argyll Group is a thick sequence of metamorphosed Neoproterozoic sedimentary rocks that outcrop across the Central Highlands of Scotland, east of the Great Glen, as well as appearing in the north of Ireland. It is a subdivision of the Dalradian Supergroup and is itself divided into four units; from oldest to youngest these are the Islay, Easdale, Crinan and Tayvallich subgroups. Islay Subgroup The lower boundary of the Islay Subgroup and hence the Argyll Group as a whole is defined at the base of the Port Askaig Tillite Formation, a diamictite which displays limestone clasts overlain by quartzite and granite clasts. The tillite is thickest in its type area and on the Garvellachs. The Schiehallion Boulder Bed of the eastern Grampians correlates with this tillite. The tillite is overlain by the Bonahaven Dolomite and then the Jura Quartzite which can reach up to 5 km thick but which is more typically between 500 and 1000m thick. Psammites and pelites occur within the se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fault (geology)
In geology, a fault is a Fracture (geology), planar fracture or discontinuity in a volume of Rock (geology), rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust (geology), crust result from the action of Plate tectonics, plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction, subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the Plane (geometry), plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geological maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone ...

Dike (geology)
In geology, a dike or dyke is a sheet of rock that is formed in a fracture of a pre-existing rock body. Dikes can be either magmatic or sedimentary in origin. Magmatic dikes form when magma flows into a crack then solidifies as a sheet intrusion, either cutting across layers of rock or through a contiguous mass of rock. Clastic dikes are formed when sediment fills a pre-existing crack.Essentials of Geology, 3rd Ed, Stephen Marshak Magmatic dikes A magmatic dike is a sheet of igneous rock that cuts across older rock beds. It is formed when magma fills a fracture in the older beds and then cools and solidifies. The dike rock is usually more resistant to weathering than the surrounding rock, so that erosion exposes the dike as a natural wall or ridge. It is from these natural walls that dikes get their name. Dikes preserve a record of the fissures through which most mafic magma (fluid magma low in silica) reaches the surface. They are studied by geologists for the clues they ...

Amphibolite
Amphibolite () is a metamorphic rock that contains amphibole, especially hornblende and actinolite, as well as plagioclase feldspar, but with little or no quartz. It is typically dark-colored and dense, with a weakly foliated or schistose (flaky) structure. The small flakes of black and white in the rock often give it a salt-and-pepper appearance. Amphibolite frequently forms by metamorphism of mafic igneous rocks, such as basalt. However, because metamorphism creates minerals entirely based upon the chemistry of the protolith, certain 'dirty marls' and volcanic sediments may also metamorphose to an amphibolite assemblage. Deposits containing dolomite and siderite also readily yield amphibolite ( tremolite-schist, grunerite-schist, and others) especially where there has been a certain amount of contact metamorphism by adjacent granitic masses. Metamorphosed basalt (metabasalt) creates ''ortho-amphibolite'' and other chemically appropriate lithologies create ''par ...

Islay
Islay ( ; , ) is the southernmost island of the Inner Hebrides of Scotland. Known as "The Queen of the Hebrides", it lies in Argyll and Bute just south west of Jura, Scotland, Jura and around north of the Northern Irish coast. The island's capital is Bowmore where the distinctive round Kilarrow Parish Church and a distillery are located. Port Ellen is the main port. Islay is the fifth-largest Scottish island and the eighth-largest List of islands of the British Isles, island of the British Isles, with a total area of almost . There is ample evidence of the prehistoric settlement of Islay and the first written reference may have come in the first century AD. The island had become part of the Gaelic Kingdom of Dál Riata during the Scotland in the Early Middle Ages, Early Middle Ages before being absorbed into the Norse Kingdom of the Isles. The later medieval period marked a "cultural high point" with the transfer of the Hebrides to the Kingdom of Scotland and the emergence of ...

Lamprophyre
Lamprophyres () are uncommon, small-volume ultrapotassic igneous rocks primarily occurring as dikes, lopoliths, laccoliths, stocks, and small intrusions. They are alkaline silica- undersaturated mafic or ultramafic rocks with high magnesium oxide, >3% potassium oxide, high sodium oxide, and high nickel and chromium. Lamprophyres occur throughout all geologic eras. Archaean examples are commonly associated with lode gold deposits. Cenozoic examples include magnesian rocks in Mexico and South America, and young ultramafic lamprophyres from Gympie in Australia with 18.5% MgO at ~250 Ma. Petrology Modern science treats lamprophyres as a catch-all term for ultrapotassic mafic igneous rocks which have primary mineralogy consisting of amphibole or biotite, and with feldspar in the groundmass. Lamprophyres are not amenable to classification according to modal proportions, such as the system QAPF, because of their peculiar mineralogy, nor compositional discrimination diagrams, ...

Quartzite
Quartzite is a hard, non- foliated metamorphic rock that 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, and hence quartzite is a metasandstone. 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 resist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
