Abstract

New sesmostratigraphic model has been established for the sedimentary cover of the North-Chukchi basin. Based on the model interpretation of the main paleogeographic events within the territory was performed. We identify three stage in the post-rift sedimentary history of the North-Chukchi basin: Late Cretacerous to Paleocene stage when strong progradation of shelf sedimentary packages was occurred, Mid Eocene — Miocene, with gradual infilling of the basin from different sides and Late Miocene to Present stage with present shapes of the shelf and slow clinoform complex aggradation.
