Ob-Zaisan, Altai-Sayan and East Sayan-Yenisei orogens: major features of tectonic development
The paper presents tectonic (geodynamic) formative environments of the lithotectonic units underlying protrusions of paleo-Precambrian continental crust along the SW margin of Siberian Platform; a study of the age range of the ocean basins and basements of the microcontinents, mid-Paleozoic lithotectonic units of the Altai and Tyva-Sayan active margin belts, along with the subduction-accretion, accretion-collision and collision edifices across the whole region and the repeated collision structures is carried out.
