Gravity Anomalies Of Britain And Ireland
Variations in the strength of gravity occur from place to place according to the density distribution of the rocks beneath the surface. Such gravity anomalies have been mapped across the British Isles and adjacent areas and they reveal aspects of these islands’ geological structure. Negative anomalies Negative gravity anomalies are associated with local deficiencies in mass due to volumes of rock which are less dense than the average. Typically these anomalies are associated with granite plutons and with sedimentary basins. Gravity anomaly maps of the British Isles are interpreted as indicating the presence of granite plutons in the following areas. The list is not exhaustive: *Galloway, UK *Cheviot Hills, UK *Mountains of Mourne, UK *Connemara, Ireland *Donegal, Ireland *South West England (Cornubian batholith and Haig Fras granite), UK *Askrigg Block (Yorkshire Dales), UK *Alston Block (North Pennines), UK *Grampian Highlands (Cairngorms etc.), UK The Weardale Granite, a bath ...

Gravity
In physics, gravity () is a fundamental interaction which causes mutual attraction between all things with mass or energy. Gravity is, by far, the weakest of the four fundamental interactions, approximately 1038 times weaker than the strong interaction, 1036 times weaker than the electromagnetic force and 1029 times weaker than the weak interaction. As a result, it has no significant influence at the level of subatomic particles. However, gravity is the most significant interaction between objects at the macroscopic scale, and it determines the motion of planets, stars, galaxies, and even light. On Earth, gravity gives weight to physical objects, and the Moon's gravity is responsible for sublunar tides in the oceans (the corresponding antipodal tide is caused by the inertia of the Earth and Moon orbiting one another). Gravity also has many important biological functions, helping to guide the growth of plants through the process of gravitropism and influencing the circ ...

Yorkshire Dales
The Yorkshire Dales is an upland area of the Pennines in the Historic counties of England, historic county of Yorkshire, England, most of it in the Yorkshire Dales National Park created in 1954. The Dales comprise river valleys and the hills rising from the Vale of York westwards to the hilltops of the Pennine Drainage divide, watershed. In Ribblesdale, Dentdale and Garsdale, the area extends westwards across the watershed, but most of the valleys drain eastwards to the Vale of York, into the River Ouse, Yorkshire, Ouse and the Humber. The extensive limestone cave systems are a major area for caving in the UK and numerous walking trails run through the hills and dales. Etymology The word ''Dale (landform), dale'', like ''dell'', is derived from the Old English word ''dæl''. It has cognates in the North Germanic languages, Nordic/Germanic languages, Germanic words for valley (''dal'', ''tal''), and occurs in valley names across Yorkshire and Northern England. Usage here may have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vale Of Eden
The Vale of Eden is formed by the course of the River Eden, one of the major rivers of Northwest England. It is however of much greater extent than the actual valley of the river, lying between the Cumbrian Mountains (more usually referred to as the Lake District), and the northern part of the Pennine Range. It lies entirely within the county of Cumbria. The river has its source in the peat bogs below Hugh Seat, in the dale of Mallerstang. At first it determinedly sets off South (as Hellgill Beck) before turning back North for the rest of its course – except just before its outlet into the sea which it enters from the East. The Eden passes through the market towns of Kirkby Stephen and Appleby-in-Westmorland, once the county town of Westmorland. It then bypasses, but remains close to, Penrith where it receives the waters of Ullswater via the River Eamont, its major tributary. Via some ancient villages and fine bridges it reaches and passes through Carlisle, the major city ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

North Channel Basin
North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. ''North'' is a noun, adjective, or adverb indicating direction or geography. Etymology The word ''north'' is related to the Old High German ''nord'', both descending from the Proto-Indo-European unit *''ner-'', meaning "left; below" as north is to left when facing the rising sun. Similarly, the other cardinal directions are also related to the sun's position. The Latin word ''borealis'' comes from the Greek '' boreas'' "north wind, north", which, according to Ovid, was personified as the wind-god Boreas, the father of Calais and Zetes. ''Septentrionalis'' is from ''septentriones'', "the seven plow oxen", a name of ''Ursa Major''. The Greek ἀρκτικός (''arktikós'') is named for the same constellation, and is the source of the English word ''Arctic''. Other languages have other derivations. For example, in Lezgian, ''kefer'' can mean ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moray Firth Basin
Moray () gd, Moireibh or ') is one of the 32 local government council areas of Scotland. It lies in the north-east of the country, with a coastline on the Moray Firth, and borders the council areas of Aberdeenshire and Highland. Between 1975 and 1996 Moray, with similar boundaries, was a district of the then Grampian Region. History The name, first attested around 970 as ', and in Latinised form by 1124 as ', derives from the earlier Celtic forms *''mori'' 'sea' and *''treb'' 'settlement' (c.f. Welsh ''môr-tref''). During the Middle Ages, the Province of Moray was much larger than the modern council area, also covering much of what is now Highland and Aberdeenshire. During this period Moray may for a time have been either an independent kingdom or a highly autonomous vassal of Alba. In the early 12th century, Moray was defeated by David I of Scotland following a conflict with Óengus of Moray, and rule over the area was passed to William fitz Duncan. After that the titl ...

Raydale
Raydale (also known as Raydaleside) is a dale on the south side of Wensleydale in North Yorkshire, England. The northern part of the dale is the valley of the River Bain, which flows out of Semerwater, one of very few lakes in the Yorkshire Dales. Above the lake the dale is drained by smaller becks, and is joined by two smaller dales, Cragdale on the east and Bardale on the west. There are three hamlets in the dale, Countersett, Marsett and Stalling Busk. The village of Bainbridge lies at the mouth of the dale. The dale is a broad, flat-bottomed U-shaped valley U-shaped valleys, also called trough valleys or glacial troughs, are formed by the process of glaciation. They are characteristic of mountain glaciation in particular. They have a characteristic U shape in cross-section, with steep, straight s ..., with a significant woodland cover around Semerwater and the other water courses.

Batholith
A batholith () is a large mass of intrusive igneous rock (also called plutonic rock), larger than in area, that forms from cooled magma deep in Earth's crust. Batholiths are almost always made mostly of felsic or intermediate rock types, such as granite, quartz monzonite, or diorite (see also ''granite dome''). Formation Although they may appear uniform, batholiths are in fact structures with complex histories and compositions. They are composed of multiple masses, or ''plutons'', bodies of igneous rock of irregular dimensions (typically at least several kilometers) that can be distinguished from adjacent igneous rock by some combination of criteria including age, composition, texture, or mappable structures. Individual plutons are solidified from magma that traveled toward the surface from a zone of partial melting near the base of the Earth's crust. Traditionally, these plutons have been considered to form by ascent of relatively buoyant magma in large masses called ''p ...

Weardale Granite
The North Pennine Batholith, also known as the Weardale Granite is a granitic batholith lying under northeast England, emplaced around 400 million years ago in the early Devonian.Kimbell, G.S., B. Young, D. Millward and Q. G. Crowley (2010). 'The North Pennine batholith (Weardale Granite) of northern England: new data on its age and form', ''Proceedings of the Yorkshire Geological Society'' 58, 107-128; do10.1144/pygs.58.1.273/ref> The batholith consists of five plutons, the Tynehead, Scordale, Rowlands Gill, Cornsay and Weardale plutons. The Weardale Granite pluton is the largest and the only one that has been proved (sampled), after the Rookhope Borehole confirmed Martin Bott's hypothesis that a large negative gravity anomaly under Weardale represented a low-density igneous intrusion. History of Study In 1934, Kingsley Dunham published a paper proposing that ore deposits in the Alston Block were formed due to a granite intrusion beneath Weardale. This was later tested by ...

Cairngorms
The Cairngorms ( gd, Am Monadh Ruadh) are a mountain range in the eastern Highlands of Scotland closely associated with the mountain Cairn Gorm. The Cairngorms became part of Scotland's second national park (the Cairngorms National Park) on 1 September 2003. Although the Cairngorms give their name to, and are at the heart of, the Cairngorms National Park, they only form one part of the national park, alongside other hill ranges such as the Angus Glens and the Monadhliath, and lower areas like Strathspey. The Cairngorms consists of high plateaux at about above sea level, above which domed summits (the eroded stumps of once much higher mountains ) rise to around . Many of the summits have tors, free-standing rock outcrops that stand on top of the boulder-strewn landscape. In places, the edges of the plateau form steep cliffs of granite and they are excellent for skiing, rock climbing and ice climbing. The Cairngorms form an arctic-alpine mountain environment, with tundra-like ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
