Tectonic subdivision of the Chukchi and East Siberian Seas
A. O. Mazarovich and S. Yu. Sokolov
Abstract
A tentative tectonic subdivision for the Chukchi and East Siberian
seas has been created based on the processing and analysis of new satellite
altimetry and magnetic data and published materials that include
information in electronic formats. The Chukchi Sea shelf is composed of
correlatives of the Alaskan tectonic zones. The main Alaskan thrust does
not stretch into Wrangel Island but is instead located in the region of the
South Chukchi Sea Basin. Most part of the shelf is occupied by a zone of
zero or slight deformation. The North Chukchi Sea Basin along with the
Vilkitsky Trough and the region of maximum subsidence in the Colville
Trough make a single entity, the Novosibirsk-Alaska Basin.
