Abstract
The special issue is focused on the problems of tectonics, paleogeography, geodynamic evolution, and mineral resources of the continental margins of the Russian Arctic. This topic is relevant, since the knowledge of the geologic structure of the Arctic Ocean and its formation and evolution can solve many global problems of geology and important regional problems, including the formation of oil- and gas-bearing sedimentary basins as well as prospecting for and development of diamonds and deposits of nonferrous, noble, rare-earth, and other minerals. In previous issues of Russian Geology and Geophysics, considerable attention was paid to the geology and oil and gas potential of the Arctic. In this special issue, emphasis is placed on the tectonics, stratigraphy, paleogeography, and petrology of the Arctic continental margins of Russia, the development of tectonic and geodynamic models for key structures, and diamond content and metallogeny of Arctic zones of the Siberian Platform, Chukotka, and the Kola Peninsula.
