Sidlaws
The Sidlaws are a range of hills in the counties of Perthshire and Angus in Scotland that extend for 30 miles (45 km) from Kinnoull Hill, near Perth, northeast to Forfar. A continuation of the Ochils, they separate the valley of Strathmore to the north from the Carse of Gowrie on the shore of the Tay. At 1492 feet (455 metres), Craigowl Hill, north of Dundee, is the highest of the Sidlaws. Points of interest include Dunsinane Hill, mentioned in Shakespeare's play ''Macbeth'', and Auchterhouse Hill, which was the site of an ancient hill fort. The ruined observatory on Kinpurnie Hill was built in the 18th century and can be seen for many miles on the Strathmore side of the Sidlaws. There is a local legend that a poacher named Brandon Henderson lived as a hermit in the tower for seven years in order to win a £100 bet. ''Sidlaw Hills'' is also the name of a "Schottische" marching tune composed for the fiddle by Jim Watson of Blairgowrie (1868–1931). Geology The Sid ...

Strathmore, Angus
Strathmore (Gaelic: ''An Srath Mòr'') is a strath in east central Scotland running from northeast to southwest between the Grampian mountains and the Sidlaws. It is approximately 50 miles (80 km) long and 10 miles (16 km) wide. Strathmore is underlain by Old Red Sandstone but this is largely obscured by glacial till, sands and gravels deposited during the ice age. Its northeast to southwest alignment is influenced by the underlying geological structure of the area which reflects the dominant Caledonian trend of both the central lowlands and the Highlands of Scotland; its northern margin reflects the presence of the Highland Boundary Fault. Strathmore is fertile and has some of Scotland's best arable farmland, producing soft fruits and cereals. History The first recorded history of this region dates to Roman times when the Romans established a series of marching camps generally extending in a south to north direction to support the invasion and exploration northward. ...

Angus, Scotland
Angus ( sco, Angus; gd, Aonghas) is one of the 32 local government council areas of Scotland, a registration county and a lieutenancy area. The council area borders Aberdeenshire, Dundee City and Perth and Kinross. Main industries include agriculture and fishing. Global pharmaceuticals company GSK has a significant presence in Montrose in the north of the county. Angus was historically a province, and later a sheriffdom and county (known officially as Forfarshire from the 18th century until 1928), bordering Kincardineshire to the north-east, Aberdeenshire to the north and Perthshire to the west; southwards it faced Fife across the Firth of Tay; these remain the borders of Angus, minus Dundee which now forms its own small separate council area. Angus remains a registration county and a lieutenancy area. In 1975 some of its administrative functions were transferred to the council district of the Tayside Region, and in 1995 further reform resulted in the establishment of the un ...

Dunsinane Hill
Dunsinane Hill ( ) is a hill of the Sidlaws near the village of Collace in Perthshire, Scotland. It is mentioned in Shakespeare's play ''Macbeth'', in which Macbeth is informed by a supernatural being, "Macbeth shall never vanquished be, until Great Birnam wood to high Dunsinane hill Shall come against him." The hill has a height of and commands expansive views of the surrounding countryside. It consists of a late Iron Age hill fort, the ramparts of which remain obvious. The site was damaged by undocumented amateur excavations in the 19th century by antiquarians attracted to the site by its Shakespearean connection. Little of value was learned about the history of the monument from these unscientific endeavours. Dunsinane is the traditional site of a 1054 battle in which Siward, Earl of Northumbria defeated Macbeth of Scotland. The much earlier Iron Age hill fort has long been known as Macbeth's Castle, though there is no archaeological evidence that it was in use by him or a ...

Cross-bedding
In geology, cross-bedding, also known as cross-stratification, is layering within a stratum and at an angle to the main bedding plane. The sedimentary structures which result are roughly horizontal units composed of inclined layers. The original depositional layering is tilted, such tilting not being the result of post-depositional deformation. Cross-beds or "sets" are the groups of inclined layers, which are known as cross-strata. Cross-bedding forms during deposition on the inclined surfaces of bedforms such as ripples and dunes; it indicates that the depositional environment contained a flowing medium (typically water or wind). Examples of these bedforms are ripples, dunes, anti-dunes, sand waves, hummocks, bars, and delta slopes.Collinson, J.D., Thompson, D.B., 1989, Sedimentary Structures (2nd ed): Academic Division of Unwin Hyman Ltd, Winchester, MA, XXX p.

Igneous Rock
Igneous rock (derived from the Latin word ''ignis'' meaning fire), or magmatic rock, is one of the three main The three types of rocks, rock types, the others being Sedimentary rock, sedimentary and metamorphic rock, metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from Partial melting, partial melts of existing rocks in either a Terrestrial planet, planet's mantle (geology), mantle or crust (geology), crust. Typically, the melting is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition. Solidification into rock occurs either below the surface as intrusive rocks or on the surface as extrusive (geology), extrusive rocks. Igneous rock may form with crystallization to form granular, crystalline rocks, or without crystallization to form Volcanic glass, natural glasses. Igneous rocks occur in a wide range of geological settings: shields, platforms ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sedimentary Rock
Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or biological detritus (organic matter). The geological detritus originated from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or mass movement, which are called agents of denudation. Biological detritus was formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies (marine snow). Sedimentation may also occur as dissolved minerals precipitate from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Devonian
The Devonian ( ) is a geologic period and system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, where rocks from this period were first studied. The first significant adaptive radiation of life on dry land occurred during the Devonian. Free-sporing vascular plants began to spread across dry land, forming extensive forests which covered the continents. By the middle of the Devonian, several groups of plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants appeared. The arthropod groups of myriapods, arachnids and hexapods also became well-established early in this period, after starting their expansion to land at least from the Ordovician period. Fish reached substantial diversity during this time, leading the Devonian to often be dubbed the Age of Fishes. The placoderms began dominating ...

Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schottische
The schottische is a partnered country dance that apparently originated in Bohemia. It was popular in Victorian era ballrooms as a part of the Bohemian folk-dance craze and left its traces in folk music of countries such as Argentina ("chotis"Spanish Wikipedia and "chamamé"), Finland ("jenkka"), France, Italy, Norway (""), Portugal and Brazil (''xote'', '), Spain (''chotis''), Sweden, Denmark ("schottis"), Mexico (Norteño music), and the United States, among other nations. The schottische is considered by ''The Oxford Companion to Music'' to be a kind of slower polka, with continental-European origin. The schottische basic step is made up of two sidesteps to the left and right, followed by a turn in four steps. In some countries, the sidesteps and turn are replaced by Strathspey hopping steps. Schottisches danced in Europe (in the context of balfolk), where they originated, are different from how they are danced in the United States. The European (or Continental) version (ofte ...

Siltstone
Siltstone, also known as aleurolite, is a clastic sedimentary rock that is composed mostly of silt. It is a form of mudrock with a low clay mineral content, which can be distinguished from shale by its lack of fissility.Blatt ''et al.'' 1980, pp.381-382 Although its permeability and porosity is relatively low, siltstone is sometimes a tight gas reservoir rock, an unconventional reservoir for natural gas that requires hydraulic fracturing for economic gas production. Siltstone was prized in ancient Egypt for manufacturing statuary and cosmetic palettes. The siltstone quarried at Wadi Hammamat was a hard, fine-grained siltstone that resisted flaking and was almost ideal for such uses. Description There is not complete agreement on the definition of siltstone. One definition is that siltstone is mudrock ( clastic sedimentary rock containing at least 50% clay and silt) in which at least 2/3 of the clay and silt fraction is composed of silt-sized particles. Silt is defined a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
