N2 - The Barents Plate is the largest shelf structure of the Arctic region, passed starting up Pre-Cambrian through paraplatform, platform, rift and basin phase of tectonic evolution. As a result, a sedimentary cover was formed, the total thickness of one reaches to 20 km. Three large tectono-sedimentary complexes are distinguished in the sedimentary cover. They are: a lower terrigenous-carbonate complex of Paleozoic age, a middle mainly carbonate complex of Upper Devonian-Permian age and an upper terrigenous complex of Permian-Cenozoic age. The Barents Plate has mainly continental type of Earth crust, although in some limited areas a diminution of crust thickness to 25-30 km is fixed (Gramberg et al., 1988). A main idea of this paper is to show that these peculiarities of the sedimentary cover, basement and crust as a whole a results of uninterrupted developing of rift processes in the Barents Plate during Phanerozoic and also Late Proterozoic time.
