The evolution of the Akademicheskaya structure in the North Chukchi basin and its relationship with the evolution of the Wrangel-Herald thrust zone

The structure and the principal evolution stages of the Akademicheskaya consedimentary structure in the North Chukchi sedimentary basin are discussed. The formation of the discussed structure took place under the effects of compressional strain from the Wrangel-Herald fold-thrust zone. This took two stages: Late Cimmerian, which contributed the most to the formation of the structure and was manifested most intensively in the first half of the Late Cretaceous, and a less intensive stage that probably occurred in the Miocene.
