Аннотация:The studies conducted by the Yuzhmorgeologiya State Scientific Centre within the Yenisei Bay of the Kara Sea in
2007-2013 have resulted in obtaining some initial understanding of geological structure of the area, that previously
was not explored by seismic exploration and seabed geochemical sampling. Geological and geophysical techniques
in combination with gravity and magnetic surveys that were conducted along seismic lines allowed for revealing some
new and unexpected features of the Yenisei Bay geological structure. In particular, in the upper part of the section a
succession of Mesozoic rocks was discovered, whose structure allows for referring the study area to West-Siberian
Petroleum Basin. Furthermore, some tentative assessments of potential hydrocarbon resources were made.
