【 摘 要 】

Terrigenous deposits of the productive PK1horizon in Pokursk suite of Pur-Tazovsk area (Yamalo-Nenets Autonomous Territory) were studied to specify the structure and identify the formation features. Complex horizon structure of sequential silt, mudrock interbedding and alternation has been identified. Littoral-marine type of sedimentation (occurring during the total marine transgression increase) by the help of genetic rock features identified during the core sampling and by the granulometry and X-ray-phase results analysis has been determined.
