Ob-­Zaisan, Altai­-Sayan and East Sayan­Yenisei 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.
Keywords: crustal continental protrusion, microcontinent, ocean basin, active margin belt, subduction-­accretion, accretion-­collision, collision, repeated collision structures.
