The article describes the results of field observations in the natural outcrops of the Pre-Yenisei zone of the Siberian Platform. The thrust deformations of Riphean-Paleozoic and Triassic rocks are characterized. It made possible to substantiate a wide manifestation of tectonic movements of the eastern orientation, which can cause hydrocarbons to flow from the unique West Siberian petroleum province to the traps of the western margin of the Tunguska syneclise. The traps are complex dislocations formed in the Riphean-Phanerozoic time. Such a geological situation makes it possible to hope for discovering new rich oil and gas accumulations that can be connected with minimum costs to pipeline routes from already discovered West-Siberian deposits, which can be facilitated by the dilapidated structures of the “Stalin” railroad.

Keywords: thrust zones, overturned rock bedding, prospect features.
