Abstract

Summary

In 2011–2016 there were carried out investigations in order to study the regional peculiarities of the geological structure of sedimentary basins of the East Siberian Sea continental margin. The RV Geolog Dmitriy Nalivkin executed integrated regional marine exploration in the area of more than 52,200 km2 (3,600 lkm) and the RV Nikolay Trubyatchinsky conducted works in the area of 107,000 km2 (4,000 lkm) in the eastern part. The survey range consisted of 2D offshore seismic, shipboard gravity measurements and differential hydromagnetometry. The crustal structure has been studied to a depth of 22–30 km. The sedimentary cover in transitional area continent - ocean has been studied to a depth of 14.0 km. In the consolidated crust section there has been found the Archean-Proterozoic crystalline basement of an ancient platform, weakly dislocated Paleozoic-Mesozoic intermediate structural stage and the basin Upper Cretaceous-Cenozoic sedimentary cover. The expected oil and gas geological resources within the studied part of sedimentary basins of the East Siberian Sea continental margin are a little over 1.0 billion TOE. As part of the generalizing studies the seismostratigraphic model of the East Siberian shelf continental margin and the adjacent deep water areas has been composed taking into account modern seismic data.
