RELATION OF THE WEST SIBERIAN HYDROGRAPHIC SYSTEM WITH BASEMENT FAULTS AND STRUCTURES OF THE SEDIMENTARY MANTLE

Abstract

Considered is the relation of hydrographic elements and the connection of planetary and local fracturing with plicative structures of the sedimentary mantle. The most widely spread, angles of incidence and bending of straight river valleys speak of the presence of six systems of planetary fracturing that are common everywhere. Regional fracturing is a combination of faults of one or more systems belonging to the general planetary fault network. Local fracturing is associated with the time of laying and formation of plicative structures and morphostructures, and it is secondary in relation to the planetary one. The author establishes connections between the direction and morphology of local structures and the orientation of disjunctive morphostructures.
