| Abstract: | This paper describes the structure and the principal evolutionary stages of the Ushakov postdeposition anticline zone, which
is located in the western part of the Chukchi Basin. The Albian-Upper Cretaceous deposits that filled riftogenic zones and
the Paleocene-Lower Neocene rocks that formed under the conditions of continuing spreading make up the sedimentary cover,
which has undergone substantial deformation because of strike-slip motions. As a result of paleoreconstructions, the principal
period of formation for this structure was determined as the Paleocene-Late Miocene, when strike-slip motions of blocks beneath
the South Chukchi Basin occurred. |
