About Perspectives of Oil-and-Gas Content of The Riphean Sedimentary Rocks in the Northwest Part of Kaltasynsky Aulacoge

The basic features of a structure of the Riphean sedimentary rocks in the edge of Kaltasynsky aulacogene and their oil-and-gas content are considered. The transformants of the gravity field reflecting a density structure of the Riphean sedimentary rocks are constructed. Zones of «decrease of density», presumably bound with areas of sedimentary rocks burial that have good reservoir properties are detected.
