Abstract
The eastern part of the Russian Arctic Shelfs represents one of the most unexplored part of the regions, where the significant oil and gas prospects could be discovered. Seismic, magnetic, gravimetric data and geological survey data from surrounding continent and islands were gathered and obtained in current research. As a result, the main tectonic events that took a place during Paleozoic, Mesozoic and Cenozoic time in the Chukchi margin were determined. Seismic stratigraphy analyses were exploit to achieve a stratigraphic model. Five and Six seismic complexes were indicated in North and South Chukchi correspondently. The main tectonic events were associated to regional unconformities traced by seismic. Paleogeographic maps for main tectonic events in Mesozoic were compiled. This information enable to gain more detailed geological model of studied area. The main oil and gas potential related to Triassic, Jurassic and Cretaceous source rocks. The perspective reservoirs connected with Cretaceous analogs occurred in North Slope.
