Based on the lithofacies and structural analysis we consider a new variant of the structuralfacies zonation of the Bazhenov horizon (Tithonian — lower Berriasian) in the north-eastern part of West Siberia. The low content of terrigenous sedimentary material in high-carbon facies the bazhenov formation, due to its capture of relatively deep Pur-Tazovsky paleobasins, which formed the cone of the Yenisei-Khatanga sea strait. Pur-Tazovsky basin filled with the yanovstanskaya formation, he adjoined from the north-east to extensive relatively shallow Obsky paleobasin — the accumulation of black shale bazhenov formation.
