The features of the Paleozoic-Mesozoic complexes of Kiber Cape (Chukotka, Arctic Russia): a structural-deforma-tion analysis

Three major regional deformation stages of Central Chukotka tectonic evolution were determined in Paleozoic-Mesozoic deposits of Kiber Cape. The research was based on a structural analysis of the linear and planar elements. Ellesmerian (Late Devonian) structural parageneses were masked during (at le...

Description
Summary:Three major regional deformation stages of Central Chukotka tectonic evolution were determined in Paleozoic-Mesozoic deposits of Kiber Cape. The research was based on a structural analysis of the linear and planar elements. Ellesmerian (Late Devonian) structural parageneses were masked during (at least) two phases of young Mesozoic-Cenozoic deformations: syncollisional North-North-East - South-South-West and North-West - South-East regional compressions and post-collisional extension of various directions, followed the compressions. The structural data comparison was made for Kiber Cape region, South-Anyui suture and Western Chukotka sector. It was emphasized that these regional units have similar structure styles and coeval phases of the tectonic transformations.
