Bass Rock
The Bass Rock, or simply the Bass (), ( gd, Creag nam Bathais or gd, Am Bas) is an island in the outer part of the Firth of Forth in the east of Scotland. Approximately offshore, and north-east of North Berwick, it is a steep-sided volcanic rock, at its highest point, and is home to a large colony of gannets. The rock is uninhabited, but historically has been settled by an early Christian hermit, and later was the site of an important castle, which after the Commonwealth period was used as a prison. The island belongs to Hew Hamilton-Dalrymple, whose family acquired it in 1706, and before to the Lauder family for almost six centuries. The Bass Rock Lighthouse was constructed on the rock in 1902, and the remains of an ancient chapel survive. The Bass Rock features in many works of fiction, including ''Catriona'' by Robert Louis Stevenson, ''The Lion Is Rampant'' by the Scottish novelist Ross Laidlaw and ''The New Confessions'' by William Boyd.

Islands Of The Forth
The Islands of the Forth are a group of small islands located in the Firth of Forth and in the estuary of the River Forth on the east coast of Scotland. Most of the group lie in the open waters of the firth, between the Lothians and Fife, with the majority to the east of the city of Edinburgh. Two islands lie further west in the river estuary. The islands have a varied geology and history; over the centuries, several have had both ecclesiastical connections and a history of involvement in military occupations. Various lighthouses and other aids to navigation have been erected on the islands and skerries — one of these dates to the 17th century. But only one of the islands still has year-round human inhabitants. The area has diverse bird and sea life. The scientific name for the northern gannet was chosen in recognition of this bird's connection with the Bass Rock. There are only a few islands off the coast of eastern Scotland, and most of them of any significant size are inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Boyd (writer)
William Andrew Murray Boyd (born 7 March 1952) is a Scottish novelist, short story writer and screenwriter. Biography Boyd was born in Accra, Gold Coast, (present-day Ghana), to Scottish parents, both from Fife, and has two younger sisters. His father Alexander, a doctor specialising in tropical medicine, and Boyd's mother, who was a teacher, moved to the Gold Coast in 1950 to run the health clinic at the University College of the Gold Coast, Legon (now the University of Ghana). In the early 1960s the family moved to western Nigeria, where Boyd's father held a similar position at the University of Ibadan. Boyd spent his early life in Ghana and Nigeria and, at the age of nine, went to a preparatory school and then to Gordonstoun school in Scotland, and, after that, to the University of Nice in France, followed by the University of Glasgow, where he gained an M.A. (Hons) in English & Philosophy, and finally Jesus College, Oxford. His father died of a rare disease when Boyd was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Craigleith
Craigleith ( gd, Creag Lìte) is a small island in the Firth of Forth off North Berwick in East Lothian, Scotland. Its name comes from the Scottish Gaelic ''Creag Lìte'' meaning "rock of Leith". It is at its highest point. Geography and geology Craigleith is part of a chain of four islands near North Berwick, along with Bass Rock, Fidra and the Lamb. Of these, it is the closest to the town's harbour. Like these other nearby islands, Craigleith is a bird colony. Divers often explore the area around the island. Craigleith is a laccolith, a lava dome. (The Lothians are dotted with evidence of ancient volcanic activity, such as the Bass Rock and Arthur's Seat.) Craigleith is made up of essexite, which is popular for making curling stones. History and wildlife Historically, Craigleith was a rabbit warren, where the animals were deliberately bred for food. Rabbits were wiped out by myxomatosis in the 1950s. They were mysteriously re-introduced onto the island in 2008, and some ha ...

Hugh Miller
Hugh Miller (10 October 1802 – 23/24 December 1856) was a self-taught Scottish geologist and writer, folklorist and an evangelical Christian. Life and work Miller was born in Cromarty, the first of three children of Harriet Wright (''bap''. 1780, ''d''. 1863) and Hugh Miller (''bap''. 1754, ''d''. 1807), a shipmaster in the coasting trade. Both parents were from trading and artisan families in Cromarty. His father died in a shipwreck in 1807, and he was brought up by his mother and uncles. He was educated in a parish school where he reportedly showed a love of reading. It was at this school that Miller was involved in an altercation with a classmate in which he stabbed his peer's thigh. Miller was subsequently expelled from the school following an unrelated incident. At 17 he was apprenticed to a stonemason, and his work in quarries, together with walks along the local shoreline, led him to the study of geology. In 1829 he published a volume of poems, and soon afterwards ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Hutton
James Hutton (; 3 June O.S.172614 June 1726 New Style. – 26 March 1797) was a Scottish geologist, agriculturalist, chemical manufacturer, naturalist and physician. Often referred to as the father of modern geology, he played a key role in establishing geology as a modern science. Hutton advanced the idea that the physical world's remote history can be inferred from evidence in present-day rocks. Through his study of features in the landscape and coastlines of his native Scottish lowlands, such as Salisbury Crags or Siccar Point, he developed the theory that geological features could not be static but underwent continuing transformation over indefinitely long periods of time. From this he argued, in agreement with many other early geologists, that the Earth could not be young. He was one of the earliest proponents of what in the 1830s became known as uniformitarianism, the science which explains features of the Earth's crust as the outcome of continuing natural processes ...

Intrusion
In geology, an igneous intrusion (or intrusive body or simply intrusion) is a body of intrusive igneous rock that forms by crystallization of magma slowly cooling below the surface of the Earth. Intrusions have a wide variety of forms and compositions, illustrated by examples like the Palisades Sill of New York and New Jersey; the Henry Mountains of Utah; the Bushveld Igneous Complex of South Africa; Shiprock in New Mexico; the Ardnamurchan intrusion in Scotland; and the Sierra Nevada Batholith of California. Because the solid country rock into which magma intrudes is an excellent insulator, cooling of the magma is extremely slow, and intrusive igneous rock is coarse-grained (phaneritic). Intrusive igneous rocks are classified separately from extrusive igneous rocks, generally on the basis of their mineral content. The relative amounts of quartz, alkali feldspar, plagioclase, and feldspathoid is particularly important in classifying intrusive igneous rocks. Intrusions ...

Dinantian
Dinantian is the name of a series (stratigraphy), series or Epoch (reference date), epoch from the Lower Carboniferous system (stratigraphy), system in Europe. It can stand for a series of rocks in Europe or the time span in which they were deposited. The Dinantian is equal to the lower part of the Mississippian age, Mississippian series in the international geologic timescale of the International Commission on Stratigraphy, ICS. The Dinantian is named for the Belgian city of Dinant where strata of this age occur. The name is still used among European geologists. Earlier terms for the Dinantian were Bernician Series, Bernician from the Anglo-Scottish borderland, and Avonian (divided into upper (Kidwellian) and lower (Clevedonian) substages) from Kidwelly on the Welsh and Clevedon on the English sides of the Bristol Channel.

Carboniferous
The Carboniferous ( ) is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period million years ago ( Mya), to the beginning of the Permian Period, million years ago. The name ''Carboniferous'' means "coal-bearing", from the Latin '' carbō'' ("coal") and '' ferō'' ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern 'system' names, it was coined by geologists William Conybeare and William Phillips in 1822, based on a study of the British rock succession. The Carboniferous is often treated in North America as two geological periods, the earlier Mississippian and the later Pennsylvanian. Terrestrial animal life was well established by the Carboniferous Period. Tetrapods (four limbed vertebrates), which had originated from lobe-finned fish during the preceding Devonian, became pentadactylous in and diversified during the Carboniferous, including early amphibian line ...

Trachyte
Trachyte () is an extrusive igneous rock composed mostly of alkali feldspar. It is usually light-colored and aphanitic (fine-grained), with minor amounts of mafic minerals, and is formed by the rapid cooling of lava enriched with silica and alkali metals. It is the volcanic equivalent of syenite. Trachyte is common wherever alkali magma is erupted, including in late stages of ocean island volcanismMacDonald 1983, pp. 51-52 and in continental rift valleys, above mantle plumes,Philpotts and Ague 2009, pp. 390-394 and in areas of back-arc extension. Trachyte has also been found in Gale crater on Mars. Trachyte has been used as decorative building stone and was extensively used as dimension stone in the Roman Empire and the Republic of Venice. Chemical composition Trachyte has a silica content of 60 to 65% and an alkali oxide content of over 7%. This gives it less SiO2 than rhyolite and more (Na2O plus K2O) than dacite. These chemical differences are consistent with the positio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phonolite
Phonolite is an uncommon extrusive rock, of intermediate chemical composition between felsic and mafic, with texture ranging from aphanitic (fine-grained) to porphyritic (mixed fine- and coarse-grained). Phonolite is a variation of the igneous rock trachyte that contains nepheline or leucite rather than quartz. Its intrusive equivalent is nepheline syenite. Phonolite is typically fine grained and compact. The name ''phonolite'' comes from the Ancient Greek meaning "sounding stone" due to the metallic sound it produces if an unfractured plate is hit; hence, the English name ''clinkstone'' is given as a synonym. Formation Unusually, phonolite forms from magma with a relatively low silica content, generated by low degrees of partial melting (less than 10%) of highly aluminous rocks of the lower crust such as tonalite, monzonite and metamorphic rocks. Melting of such rocks to a very low degree promotes the liberation of aluminium, potassium, sodium and calcium by melting of f ...

Volcanic Plug
A volcanic plug, also called a volcanic neck or lava neck, is a volcanic object created when magma hardens within a vent on an active volcano. When present, a plug can cause an extreme build-up of high gas pressure if rising volatile-charged magma is trapped beneath it, and this can sometimes lead to an explosive eruption. In a plinian eruption the plug is destroyed and ash is ejected. Glacial erosion can lead to exposure of the plug on one side, while a long slope of material remains on the opposite side. Such landforms are called crag and tail. If a plug is preserved, erosion may remove the surrounding rock while the erosion-resistant plug remains, producing a distinctive upstanding landform. Examples of volcanic plugs Africa Near the village of Rhumsiki in the Far North Province of Cameroon, Kapsiki Peak is an example of a volcanic plug and is one of the most photographed parts of the Mandara Mountains. Spectacular volcanic plugs are present in the center of La Gomer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
