Much of the Southern Uplands are comprised of Ordovician and Silurian rocks that were once sands and muds deposited on the floor of the Iapetus Ocean. All are individual in some respect or other. In den Southern Uplands Die Bergregion der Southern Uplands ist das südlichste Gebiet der geographischen Dreiteilung Schottlands . Lapworth was the first scientist to recognise the well-defined change in graptolite assemblages throughout the sequence of … Structural interpretations of the … Much of the Southern Uplands are comprised of Ordovician and Silurian rocks that were once sands and muds deposited on the floor of the Iapetus Ocean. © Laurie Campbell. A., Floyd, J D, Barnes, R.P, and Phillips, E. R.British regional geology: South of Scotland. The Southern Uplands contain 10 or more distinct deep-water stratigraphic sequences consisting of basalt and chert and/or graptolitic shale, below thick greywackes. This region of Scotland represents the point where Scotland and England came together with the closure of an ancient ocean called The Iapetus. Carboniferous sedimentary rocks of the Midland Valley, and separate English basins, overlap onto the Southern Uplands. Although the Southern Upland Fault (SUF) is widely recognized as a major Caledonoid crustal structure in south Scotland, the derivation of the term ‘SUF’ has never been definitively established. During the collision, sediments were scraped off the floor of Iapetus and heaped onto the edge of the northern continent. MacAdam A.D., Clarkson E.N.K., Stone, P. (editors) 1993 .Scottish Borders geology: an excursion guide.Edinburgh, Scottish Academic Press. The terrane formed as an accretionary thrust complex at the Laurentian continental margin during Late Ordovician to mid Silurian subduction of the Iapetus Ocean. However, despite the overall variety, by far the largest area is underlain by Ordovician and Silurian, deep-marine sedimentary rocks, … Deposited over a 70 million year period, between 490 and 420 million years ago, these rocks bear testimony to the closure of the Iapetus Ocean, with the coming together of what is now the North American continent and Northern Europe. The area is notable for its glacial deposits, particularly drumlins, and for its coastal landforms, particularly salt marshes, sand flats and mudflats. The Southern Uplands Fault (or occasionally Southern Upland Fault) [1] is a fault in Scotland that runs from Girvan (or more specifically from the Rhins of Galloway) to Dunbar on the East coast. This is the trace of the ancient Iapetus Ocean, which once divided two continents. Not only are the greywackes, shales and igneous emplacements still visible but one can also decipher the fault lines upon which the Southern Uplands were thrusted onto land, the power of plate … These Southern Uplands Terrane plutons appear to be magmatic ‘fingers’ rising from larger, deeper intrusive complexes that resided at depth. The Southern Uplands contain 10 or more distinct deep-water stratigraphic sequences consisting of basalt and chert and/or graptolitic shale, below thick greywackes. Deposited over a 70 million year period, between 490 and 420 million years ago, these rocks bear testimony to the closure of the Iapetus Ocean, with the coming together of what is now the North American continent and Northern Europe.
