Age of relief of Mesozoic structures of Chukchi Peninsula

Abstract

A topography closely resembling the present one came into being on the Mesozoic structures in the north central and western Chukchi Peninsula at the end of the Mesozoic era and has not been transformed during the whole Cenozoic. The relief remodeling is mostly due to climatic rhythms, which control special features of placers formation, redeposition and covering with younger sediments.
