Arctic geosynclinal belt
ARCTIC GEOSYNCLINAL BELT (EN: Arctic geosynclinal belt; DE: arktischer Geosynklinalgurtel, arktisches Ceosynklinalgebiet; FR: zone geosynclinale arctique; ES: cinturon geosinclinal ártico; RU: арктический геосинклинальный пояс) is the mobile belt of the Earth's crust, which encircles the depression of the Arctic ocean at the south.
The most clearly expressed links of the Arctic geosynclinal belt are the Middle Paleozoic (Early Hercynian) system of the Canadian Arctic archipelago, and the Early Paleozoic (Caledonian) system of the northern Greenland (Peary Land, and others); there also belong within the limits of the Arctic geosynclinal belt the Novosibirsk-Chukotka Mesozoic system and the Paleozoic-Mesozoic system, the Brooks range at the north of Alaska. There proceeds between the north-eastern Greenland and Severnaya Zemlya (Northern Land) the joint of the Arctic and Ural-Mongolian belts. There belong to the region of this joint the folded structures of the Novaya Zemlya (New Land), Severnaya Zemlya (Northern Land), and Taimyr Peninsula. During the pre-Mesozoic time, the Arctic geosynclinal belt probably encircled the so called Hyperborean continental plate, which has later experienced the submersion and destruction.
Arctic geosynclinal belt is distinguished not by all geologists.
