Lying in the 1, km long East Greenland Caledonian belt (Higgins, Soper, & Leslie, ), geologically the area is divided into two parts, with crystalline (gneiss and granite) to the west and. Deposition in the Franklinian Basin was broughttoa close in the latest Devonian by the Ellesmerian orogeny, which produced the kmlong E-Wtrending North Greenland fold belt. The sediments ofthedeep water trough were displaeed southwards against the former platform margin producing a southern thin-skinnedfold and thrust belt. Get this from a library!

the Caledonian Orogeny, and each tectonic event throughout this million years can be considered as an orogenic phase. It is not essential that every local event be given a formal name, but we consider that the following names (already in the geological literature) constitute the principle phases of the Caledonian Orogeny. The Caledonian orogeny was a mountain building era recorded in the northern parts of the British Isles, Scandanavia, Svalbard, eastern Greenland and parts of north-central Europe 11/30/ © EarthStructure (2 nd ed) 5 • Ordovician to Early Devonian, roughly million years ago (Ma). • Caused by the closure of the Iapetus Ocean when the. Most parts of Greenland consist of such an old shield or are at least underlain by one. Precambrian rocks are also exposed in the innermost part of the Scoresbysund, even though only in a quite limited area, at least Precambrian rocks that have not been affected by the Caledonian orogeny. The Precambrian rocks are mostly granites and gneisses. Caledonian Orogeny million years ago, much of the Earth’s continental landmass existed as two large continents, Gondwana and Laurentia, separated by 7, km of ocean. What is now the UK was separated between them – the north of Scotland on Laurentia, and the rest on Gondwana. The two were joined during the Caledonian Orogeny.

The mountains and fjords of Greenland preserve a record of nearly four billion years of Earth history - a story of mountain building, volcanic eruptions, primitive life and ice ages. During the vast period of time, through processes of continental drift, Greenland has journeyed from the southern hemisphere through the tropics to its present polar position. This volume presents an account of. Most of the orogen front in eastern Greenland is covered by ice, and the relationships between the major Caledonian thrust sheets and the underlying cover are best seen in antiformal windows, similar to those in the Scandes. The allochthons have been divided into two groups and are referred to as ‘thin-skinned’, overlain by ‘thick-skinned’. Caledonian metamorphic patterns correspond to the gross structural levels of the orogen. The patterns are superimposed on earlier metamorphic histories in the Precambrian crystalline complexes, but they account for the sole metamorphism of Neoproterozoic to early Paleozoic sedimentary units.
