Abstract
The paper summarizes the results of analysis of inner structure of bajocian-bathonian deposits (leontiev-malyshev regional sequence) of Yamal-Gydan region. Conclusions concerning variation of stratigraphic volume of leontiev suite in Yamal-Gydan region from land to sea due to shaling out in sand beds in the base of malyshev suite are made. Regional shaling out borders for U4, U5, U6 beds on Yamal peninsula are traced by the authors. Obtained shaling out borders are lying parallel to shoreline which existed during the beds sedimentation time. Zones confined to these borders may present a certain interest as the classic structural prospects as well as non-structural ones. The highest concentration of the least will be confined to the regional shaling out border.
