Atlantic folded geosynclinal belt
ATLANTIC FOLDED GEOSYNCLINAL BELT (RU: Атлантический складчатый геосинклинальный пояс) is the Late pre-Cambrian - Paleozoic mobile belt, which is framing the Atlantic Ocean. There belong to the western part of the belt the Caledonides of the Eastern Greenland, Newfoundland and Northern Appalachians, and the Hercinides of the Southern Appalachian, which are continuing to the south along the north-western, western, and southern periphery of the Gulf of Mexico, up to the Gulf of Honduras, and there belong to the eastern part of the belt the Caledonides of the British Isles, Scandinavia, and Spitsbergen. There are observed within the South Atlantic only the fragments of the folded zones (mainly the Baikalides along the coasts of the South America and Africa).
The laying of the Atlantic folded geosynclinal belt, which belongs to the late pre-Cambrian (approximately 1 billion years ago), was accompanied by the split of the North American continent from the East European one, with the appearance within the gap of the deep basin with the crust of the oceanic type. At the end of the pre-Cambrian and during the Paleozoic, there has accumulated within this basin the thick stratum of sediments and volcanites, which has undergone the first deformations yet before the Paleozoic, and later at the end of the Ordovician and Silurian, at the start and middle of the Devonian, and at the Late Paleozoic. During the Jurassic, there have emerged the listed folded structures, which were complicated by the large thrust faults, which were oriented on the western coast of the Atlantic Ocean and within the North-Western Scotland to the west (north-west), and on the eastern coast to the east (south-east). There are known within the Atlantic folded geosynclinal belt the large basins of the mineral coals (Appalachian, and others), the deposits of asbestos (Canada), of the ores of the non-ferrous metals, and of the other useful minerals.
