LENA-YENISEI CASCADE OF MESOZOIC DEPRESSIONS IN THE NORTHERN MARGIN OF THE SIBERIAN PLATFORM IN CONNECTION WITH PETROLEUM POTENTIAL

V. S. Staroseltsev

Depths of the Jurassic-Cretaceous downwarping of the northern margin of the Siberian Platform are considered consistently, their stepped enlargement from east to west with formation of peculiar cascade is substantiated. Petroleum potential prospects are analyzed for each of its stage. The conformity of detected trends in alteration of petroleum potential to regularities, general for the whole Siberian Platform is evaluated.

Key words: Depths of the Mesozoic downwarping, petroleum potential, focal salt accumulation, nature of “cross-beds”, correlation with petroleum potential evaluation within the whole platform.
