Stages in the Structural Evolution of the Sedimentary Cover of Wrangel Island, Eastern Arctic.

Abstract—: The paper presents data on mesostructural field observations in the northern, central, and eastern parts of Wrangel Island. Numerous stages in the structural evolution of geological complexes of the fold sedimentary cover of the island are confirmed. The structures of the early stage (Early Devonian) were found in Upper Silurian-Lower Devonian and Devonian-Lower Carboniferous rocks. They include longitudinal fold deformations during the Ellesmerian tectogenesis of Alaska and Arctic Canada. The structures of northern vergence of the Middle Devonian stage within the entire territory of the island are related to collision events of the Chukotka Orogeny at the end of the Early Cretaceous.
