Belnahua
Belnahua is one of the Slate Islands, in the Firth of Lorn in Scotland, known for its deserted slate quarries. The bedrock that underpins its human history is part of the Scarba Conglomerate Formation and its value has been on record since the 16th century. Likely uninhabited before commercial quarrying commenced, under the control of the Stevenson family during the 19th century the population expanded to over 150 before the island was abandoned again in 1914. Living on a remote island in the 19th century came with significant hardships and the lives of the quarry workers have been described in unflattering terms by modern commentators, one describing them as in effect "slaves". Today, the ruined buildings and abandoned machinery lie amidst the water filled quarries and are home only to wildlife. There are very strong tidal streams in the area and this a potentially hazardous location for shipping. In 1936 the cargo vessel A cargo ship or freighter is a merchant ship that ca ...

Slate Islands
The Slate Islands are an island group in the Inner Hebrides, lying immediately off the west coast of Scotland, north of Jura and southwest of Oban. The main islands are Seil, Easdale, Luing, Shuna, Torsa and Belnahua. Scarba and Kerrera, which lie nearby are not usually included. The underlying geology of the islands is Dalradian slate, which was quarried widely until the mid-20th century. Quarry working began in 1630 and at the turn of the 20th century, the quarries were yielding some eight million slates every year. The Garvellachs lie to the southwest. Definition Unlike some of Scotland's larger archipelagos such as Orkney and the Outer Hebrides, which are distant from other islands and also have their own local authority, the Slate Islands have no formal definition. The islands from which the slate that gives rise to the name was quarried on a substantial commercial basis are Easdale, Belnahua, Luing and Seil. The website of the Slate Islands Heritage Trust also promin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fladda, Slate Islands
Fladda is one of the Slate Islands, off the west coast of Argyll and Bute, Scotland. Fladda is an islet in the Sound of Luing, between Luing and Belnahua. The name Fladda originates from the Old Norse for 'flat island'. Lighthouse Fladda lighthouse is an active lighthouse located on the Islet of Fladda, one of the Slate Islands about off Cullippol. The lighthouse was built in 1860 on project by David A. and Thomas Stevenson; it is a cylindrical masonry tower high with gallery and lantern. The tower is painted white, the lantern is black and has ochre trim; it is a minor light operated by Northern Lighthouse Board but managed privately. The light emits a two white flashes every 9 seconds. The keeper's house seems to be home to a large colony of terns.

Scarba, Lunga And The Garvellachs National Scenic Area
Scarba, Lunga and the Garvellachs is the name of one of the 40 national scenic areas of Scotland. The designated area covers the islands of Scarba, Lunga, and the Garvellachs, all of which lie in the Firth of Lorn, along with much of the surrounding seascape. The national scenic areas are defined so as to identify areas of exceptional scenery and to ensure its protection by restricting certain forms of development, and are considered to represent the type of scenic beauty "popularly associated with Scotland and for which it is renowned". The Scarba, Lunga and the Garvellachs NSA covers 6,542 ha in total, consisting of 2,139 ha of land with a further 4,402 ha being marine (i.e. below low tide). National scenic areas are primarily designated due to the scenic qualities of an area, however NSAs may well have other special qualities, for example related to culture, history, archaeology, geology or wildlife. Areas with such qualities may be protected via other national a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Islands Of Scotland
This is a list of islands of Scotland, the mainland of which is part of the island of Great Britain. Also included are various other related tables and lists. The definition of an offshore island used in this list is "land that is surrounded by seawater on a daily basis, but not necessarily at all stages of the tide, excluding human devices such as bridges and causeways". Scotland has over 790 offshore islands, most of which are to be found in four main groups: Shetland, Orkney, and the Hebrides, sub-divided into the Inner Hebrides and Outer Hebrides. There are also clusters of islands in the Firth of Clyde, Firth of Forth, and Solway Firth, and numerous small islands within the many bodies of fresh water in Scotland including Loch Lomond and Loch Maree. The largest island is Lewis and Harris which extends to 2,179 square kilometres, and there are a further 200 islands which are greater than 40 hectares in area. Of the remainder, several such as Staffa and the Flannan Isles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Firth Of Lorn
The Firth of Lorn or Lorne ( gd, An Linne Latharnach) is the inlet of the sea between the south-east coast of the Isle of Mull and the mainland of Scotland. It includes a number of islands, and is noted for the variety of wildlife habitats that are found. In 2005, a large part of the Firth became a Special Area of Conservation. Geography and geology The firth extends from the junction of the Sound of Mull and the Lynn of Lorn in the north-east, in a south-westerly direction towards Colonsay. The narrower north-eastern part is the Inner Firth, and the wider south-western part is the Outer Firth. The firth takes its name from the historic province of Lorne on the adjacent mainland. The Firth of Lorn is a continuation of the Great Glen - the Great Glen Fault runs along the north-westerm side of the firth. A conspicuous feature of the coasts of the firth is the presence of rock platforms and raised cliffs. These can be seen on the coast of Mull, on the Island of Kerrera and o ...

Pelite
A pelite (Greek: ''pelos'', "clay") or metapelite is a metamorphosed fine-grained sedimentary rock, i.e. mudstone or siltstone. The term was earlier used by geologists to describe a clay-rich, fine-grained clastic sediment or sedimentary rock, i.e. mud or a mudstone, the metamorphosed version of which would technically have been a ''metapelite''. It was equivalent to the now little-used Latin-derived term lutite.Potter, P.E., J.B. Maynard, and P.J. Depetris (2005) ''Muds and Mudstones.''

Isle Of Mull
The Isle of Mull ( gd, An t-Eilean Muileach ) or just Mull (; gd, Muile, links=no ) is the second-largest island of the Inner Hebrides (after Skye) and lies off the west coast of Scotland in the Council areas of Scotland, council area of Argyll and Bute. Covering , Mull is the fourth-largest island in Scotland and Great Britain. From 2001 to 2020, the population has gradually increased: during 2020 the populace was estimated to be 3,000, in the United Kingdom Census 2011, 2011 census it was approximately 2,800, and in 2001, it was measured at 2,667 people. It has the eighth largest Island population in Scotland. In the summer, these numbers are augmented by an influx of many tourists. Much of the year-round population lives in the colourful main settlement of Tobermory, Mull, Tobermory. There are two distilleries on the island: the Tobermory distillery, formerly named Ledaig, produces single malt Scotch whisky and another, opened in 2019 and located in the vicinity of Tir ...

Geology Of Mull
The geology of the Isle of Mull in Scotland is dominated by the development during the early Palaeogene period of a ‘ volcanic central complex’ associated with the opening of the Atlantic Ocean. The bedrock of the larger part of the island is formed by basalt lava flows ascribed to the Mull Lava Group erupted onto a succession of Mesozoic sedimentary rocks during the Palaeocene epoch. Precambrian and Palaeozoic rocks occur at the island's margins. A number of distinct deposits and features such as raised beaches were formed during the Quaternary period. Precambrian and Palaeozoic rocks The central complex is underlain by the Neoproterozoic age metamorphosed Moine rocks and is intruded into them. Moine Rocks of the Glenfinnan Group occur in places around the Mull Central Complex and others from the Glenfinnan and Morar groups occur on the Ross of Mull. Dalradian Semipelites and metalimestones of the Appin Group occur within the Loch Don Anticline in the east of the isl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palaeogene
The Paleogene ( ; also spelled Palaeogene or Palæogene; informally Lower Tertiary or Early Tertiary) is a geologic period and system that spans 43 million years from the end of the Cretaceous Period million years ago ( Mya) to the beginning of the Neogene Period Mya. It is the beginning of the Cenozoic Era of the present Phanerozoic Eon. The earlier term Tertiary Period was used to define the span of time now covered by the Paleogene Period and subsequent Neogene Period; despite no longer being recognised as a formal stratigraphic term, 'Tertiary' is still widely found in earth science literature and remains in informal use. Paleogene is often abbreviated "Pg" (but the United States Geological Survey uses the abbreviation PE for the Paleogene on the Survey's geologic maps). During the Paleogene, mammals diversified from relatively small, simple forms into a large group of diverse animals in the wake of the Cretaceous–Paleogene extinction event that ended the preceding C ...

Dike Swarm
A dike swarm (American spelling) or dyke swarm (British spelling) is a large geological structure consisting of a major group of parallel, linear, or radially oriented magmatic dikes intruded within continental crust or central volcanoes in rift zones. Examples exist in Iceland and near other large volcanoes, (stratovolcanoes, calderas, shield volcanoes and other fissure systems) around the world. They consist of several to hundreds of dikes emplaced more or less contemporaneously during a single intrusive event, are magmatic and stratigraphic, and may form a large igneous province. The occurrence of mafic dike swarms in Archean and Paleoproterozoic terrains is often cited as evidence for mantle plume activity associated with abnormally high mantle potential temperatures. Dike swarms may extend over in width and length. The largest dike swarm known on Earth is the Mackenzie dike swarm in the western half of the Canadian Shield in Canada, which is more than wide and ...
