Like the rocks of Northern England, there are rocks here that tell the tale of the convergence and collision of the ancient Laurentian, Avalonian, Baltican, Armorican and Gondwana tectonic plates and the compressive, transtentional and extensional forces that resulted. In the 1870s, Charles Lapworth studied the fossilised remains of graptolites, long-extinct marine fauna of the Ordovician and Silurian times, in these shales in Moffatdale and in the Girvan district. The first is a succession of basaltic pillow lavas … Raised estuarine deposits occur extensively along the Solway coast and provide valuable records of sea-level changes during the last 14,000 years. ^ "Overview of Southern Uplands Fault". {{notificationsCount}} Home; Keywords; Articles; Journals; Publishers {{notificationsCount}} 15: Der Rand eines Granitplutons in den Southern Uplands (Schottland). Style, scale and significance of sand bodies in the Northern and Central Belts, southwest Southern Uplands. surficial geology of New Jersey includes evidence of sustained cold climates, warm climates, and transitional periods. In 1882, Archibald Geikie became the director general of the whole Geological Survey and wanted to speed up and complete the primary survey of the UK. The Southern Upland Fault runs from near Ballantrae to Dunbar. Retrieved 27 December 2009. Structures are described from two sequences of Lower Palaeozoic rocks exposed in the Coldingham Bay area. This is the trace of the ancient Iapetus Ocean, which once divided two continents. Find out more about them by following the link. The cyclic deposition and melting of ice in the Quaternary, from 2.6Ma until 12,000 years ago led to intense erosion and redistribution of the rock material. © Scottish Natural Heritage. Jahre) ist diese Inselgruppe dann mit dem späteren England und Wales (Baltische Kontinentalplatte) aufeinandergeprallt, wobei sich die Highlands und Southern Uplands ausgebildet haben. The historical background to the naming of the fault is discussed and a definition proposed for the Southern Upland Fault ( sensu strictu ). Find link is a tool written by Edward Betts..

In Trewin, N.H. (ed) The Geology of Scotland, The Geological Society, London p191-2 Comments and Replies on “Is the Southern Uplands of Scotland really an accretionary prism?”: COMMENT This geology, coupled with the action of the ice sheets which retreated (ended) around 10,000 years ago, has produced rounded hills and smooth slopes. Geology. The Caledonian orogeny is named for Caledonia, a Latin name for Scotland. Here in the Southern Uplands, Variscan compression had less effect but nevertheless was responsible for some faulting, folding and uplift in the Carboniferous sedimentary strata. © Scottish Natural Heritage. At around 400 million years ago, at the start of the Devonian period, there was the intrusion of major granite plutons within the Southern Uplands such as the Criffell granite. The Southern Uplands contain 10 or more distinct deep-water stratigraphic sequences consisting of basalt and chert and/or graptolitic shale, below thick greywackes. ... raised and folded into a mountain chain that forms the foundation of the Southern Uplands. St Abbs – tilted rock layers at Pettico Wick near St Abbs. Glacial erosion shaped the main valleys and moulded the western uplands which are extensively ice-scoured. The Central Uplands are characterized by highly dissected low Intra-bed palaeocurrent variations in a Silurian flysch sequence, Kirkcudbrightshire, Southern Uplands, Scotland, Scottish Journal of Geology 3, 268–281. The broad, rolling hills are bound to the north by the Southern Uplands Fault, while their southern edge coincides with one of Britain’s major geological divides – the Iapetus Suture. At the end of this section, a brief synthesis summarizes the events that resulted in the amalgamation of the various terranes into the present configuration. The Southern Uplands contain 10 or more distinct deep-water stratigraphic sequences consisting of basalt and chert and/or graptolitic shale, below thick greywackes. It is now believed that this may have been triggered by a strong mantle plume or hot spot. BERGE – HIGHLANDS, LOWLANDS, SOUTHERN UPLANDS. The material that was eroded in this process became the fluvial and aeolian Permian sandstones and conglomerates we can see today in the Thornhill area. Many of the valleys on the south side of the uplands and the area around Stranraer contain large spreads of glaciofluvial deposits. Early in the Jurassic period (201 -145 Ma), much of the Southern Uplands was submerged and marine sediments must have been widespread. Southern Uplands Fault Last updated February 23, 2019 Scotland, geographical areas. Its extraordinary journey started more than 500 million years ago, when Scotland was part of a landmass lying to the south of the equator. The minor folds in the Coldingham Beds are much more complex than those found … The volcanic activity and the eruption of basaltic lavas that ensued generated a swarm of … Engineering Geology Special Publications The Southern Uplands is the least populated of mainland Scotland's three major geographic areas. The Southern Uplands is mostly composed of Silurian greywackes (the Gala Greywacke), but the Upper Ordovician/Lower Silurian Moffat Shale Group is exposed in E-W faulted inliers (formed by imbricate thrusting). The resulting mass of sediments, known as the Southern Uplands Accretionary Complex, is regarded by many to be the best-preserved ancient accretionary complex in the world. Land subsidence produced shallow lagoons. in the Late Carboniferous, extensional and transtentional tectonic forces thinned the crust and stimulated renewed igneous activity across the region. They lie south of the Southern Uplands Fault line that runs from Ballantrae on the Ayrshire coast northeastwards to Dunbar in East Lothian on the North Sea coast, a distance of some 220 km (140 mi). From 60 Ma to 55 Ma, what is now the Western seaboard of Scotland from Arran to Skye, and the North of Ireland became a centre of intense volcanic activity erupting vast amounts of basaltic magma and intruding plutons, sills and dykes far and wide into surrounding rocks. Fourth edition. The south of Scotland region is underlain by a wide variety of rocks with a geological history spanning almost 500 million years and discrete (though complementary) geological successions in each of its two terranes, separated by the Southern Upland Fault (P912381, P912382). These sequences are separated by major reverse strike faults. View Academics in Southern Uplands (Caledonian Geology) on Academia.edu. By far the most common rock types in the region are the greywacke, siltstone and shale sequences that were also beginning to be laid down in the mid-Ordovician during the continued subduction of the oceanic plate under Laurentia.Over the millions of years taken for the closure of the Iapetus Ocean, vast quantities of marine sediments, together with the sand, mud and small rock fragments that cascaded in turbidity currents down the steep slopes of Laurentia’s continental shelf onto the ocean bed, were sliced off from the subducting plate and thrust onto the Laurentian plate beneath previously stripped-off slices. 2002 The Ballantrae Complex and Southern Uplands terrane. These sequences are separated by major reverse strike faults. MacAdam A.D., Clarkson E.N.K., Stone, P. (editors) 1993 .Scottish Borders geology: an excursion guide.Edinburgh, Scottish Academic Press.

Thus the geology of each terrane is described up to the time of amalgamation, providing chapters on the Southern Uplands, Midland Valley, Northern Highland, Grampian and Hebridean terranes. Particularly striking examples of glacial streamlining are represented along the margins of the Tweed valley. It occupies some 10,000 km2 of Southern Scotland as well as about 6,000 km2 Ireland.The striking bands seen on geological maps of the region graphically display the division of the terrain into discrete units, each bounded by north-east to south-west running, parallel-strike faults.Emplacement in the accretionary prism, faulting, and rotation have resulted in units overall younging from northwest to southeast. The book is the second of two volumes on the geology of New Mexico's public lands – the first, published in 2010, dealt with the northern half of the state and, correspondingly, this volume deals exclusively with the southern regions. Scottish Journal of Geology,http://nora.nerc.ac.uk/id/eprint/508842, Hubbard, J. This fundamental Southern Upland paradox is soluble only by recognizing many strike-parallel faults, dividing the terrane into more than thirty tracts, each with its own variant of the stratigraphy and structure, and each having a lateral extent far in excess of what might be expected from the probable mechanical strength of the composing sediments.
