Coll Del Moro
Coll (; )Mac an Tàilleir (2003) p. 31 is an island located west of the Isle of Mull and northeast of Tiree in the Inner Hebrides of Scotland. Coll is known for its sandy beaches, which rise to form large sand dunes, for its corncrakes, and for Breacachadh Castle. It is in the council area of Argyll and Bute. Arinagour is the main settlement on Coll. There is a ferry terminal on the island which connects it with the mainland of Scotland. Coll also has a small airport. The island is rural in nature and has been awarded Dark Sky status. Geology Coll is formed largely from gneiss forming the Lewisian complex, a suite of metamorphic rocks of Archaean to early Proterozoic age. The eastern part of the island is traversed by numerous normal faults most of which run broadly northwest–southeast. Dolerite and camptonite dykes of Permo-Carboniferous or Tertiary age are also seen in the east of the island. Quaternary sediments include raised beach deposits which are frequent arou ...

Arinagour
Arinagour (, "shieling of the goats") is a village on the island of Coll, in the Argyll and Bute council area of Scotland. It is the main settlement on the island, and is the island's ferry terminal. It has a population of around 50. History Arinagour has been a site of human activity since prehistoric times as evidenced by a standing stone located by the shore. In 1961 it had a population of 54. Buildings Arinagour parish church is a Gothic Revival Church, with a timber roof and lancet windows, that was built in 1907. Arinagour Free Church was built circa 1880, with a belcote and pointed arch windows it became disused in 2008. There is a First World War and Second World War memorial in Arinagour, on Shore Street, in the form of a small standing stone with a memorial plaque to those locals who died in the wars. Education Arinagour Primary School is located in the village and was built in 1954. In 2022, it was reported as having only 6 pupils. Transport Coll's ferry termina ...

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 ...

Gazetteer For Scotland
The ''Gazetteer for Scotland'' is a gazetteer covering the geography, history and people of Scotland. It was conceived in 1995 by Bruce Gittings of the University of Edinburgh and David Munro of the Royal Scottish Geographical Society, and contains 25,870 entries as of July 2019. It claims to be "the largest dedicated Scottish resource created for the web". The Gazetteer for Scotland provides a carefully researched and editorially validated resource widely used by students, researchers, tourists and family historians with interests in Scotland. Following on from a strong Scottish tradition of geographical publishing, the ''Gazetteer for Scotland'' is the first comprehensive gazetteer to be produced for the country since Francis Groome's '' Ordnance Gazetteer of Scotland'' (1882–1886) (the text of which is incorporated into relevant entries). The aim is not to produce a travel guide, of which there are many, but to write a substantive and thoroughly edited description of ...

Peat
Peat is an accumulation of partially Decomposition, decayed vegetation or organic matter. It is unique to natural areas called peatlands, bogs, mires, Moorland, moors, or muskegs. ''Sphagnum'' moss, also called peat moss, is one of the most common components in peat, although many other plants can contribute. The biological features of sphagnum mosses act to create a habitat aiding peat formation, a phenomenon termed 'habitat manipulation'. Soils consisting primarily of peat are known as histosols. Peat forms in wetland conditions, where flooding or stagnant water obstructs the flow of oxygen from the atmosphere, slowing the rate of decomposition. Peat properties such as organic matter content and saturated hydraulic conductivity can exhibit high spatial heterogeneity. Peatlands, particularly bogs, are the primary source of peat; although less common, other wetlands, including fens, pocosins and peat swamp forests, also deposit peat. Landscapes covered in peat are home to sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alluvium
Alluvium (, ) is loose clay, silt, sand, or gravel that has been deposited by running water in a stream bed, on a floodplain, in an alluvial fan or beach, or in similar settings. Alluvium is also sometimes called alluvial deposit. Alluvium is typically geologically young and is not Consolidation (geology), consolidated into solid rock. Sediments deposited underwater, in seas, estuaries, lakes, or ponds, are not described as alluvium. Floodplain alluvium can be highly fertile, and supported some of the earliest human civilizations. Definitions The present Scientific consensus, consensus is that "alluvium" refers to loose sediments of all types deposited by running water in floodplains or in alluvial fans or related landforms. However, the meaning of the term has varied considerably since it was first defined in the French dictionary of Antoine Furetière, posthumously published in 1690. Drawing upon concepts from Roman law, Furetière defined ''alluvion'' (the French term for al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sediment
Sediment is a solid material that is transported to a new location where it is deposited. It occurs naturally and, through the processes of weathering and erosion, is broken down and subsequently sediment transport, transported by the action of wind, water, or ice or by the force of gravity acting on the particles. For example, sand and silt can be carried in suspension (chemistry), suspension in river water and on reaching the sea bed deposited by sedimentation; if buried, they may eventually become sandstone and siltstone (sedimentary rocks) through lithification. Sediments are most often transported by water (fluvial, fluvial processes), but also wind (aeolian processes) and glaciers. Beach sands and stream channel, river channel deposits are examples of fluvial transport and deposition (geology), deposition, though sediment also often settles out of slow-moving or standing water in lakes and oceans. Desert sand dunes and loess are examples of aeolian transport and deposition. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quaternary
The Quaternary ( ) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS), as well as the current and most recent of the twelve periods of the Phanerozoic eon. It follows the Neogene Period and spans from 2.58 million years ago to the present. The Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today); a proposed third epoch, the Anthropocene, was rejected in 2024 by IUGS, the governing body of the ICS. The Quaternary is typically defined by the Quaternary glaciation, the cyclic growth and decay of continental ice sheets related to the Milankovitch cycles and the associated climate and environmental changes that they caused. Research history In 1759 Giovanni Arduino proposed that the geological strata of northern Italy could be divided into four succ ...
