ABSTRACT
The paper deals with the geological structure, structural characteristics and the restoration of the tectonic development history of the Gydan dome-shaped uplift and the Novii port shaft, to which the Gydan gas (Gydan peninsula) and Novii port oil and gas condensate (Yamal Peninsula) fields are confined. Despite the close modern geographical position of the Yamal and Gydan peninsulas, these areas are distinguish in tectonic evolution, sedimentary cover structure and fault tectonics, which predetermine differences in petroleum potential. There is no unified tectonic structure model for the study area; the geologists opinions are different on many issues.
