DEEP STRUCTURE OF THE CONSOLIDATED BASEMENT OF THE WEST SIBERIAN PLATFORM AND ITS FOLDED SURROUNDINGS

Abstract

The deep structure of the West Siberian Plate and its folded surroundings has been imaged in geoscience transects based on geophysical surveys (DSS, CDP profiling, seismic tomography, gravity, magnetic, geothermal, MT, and remote sensing) along regional profiles. The resulting interpretative cross sections obtained by original geological-geophysical and geodynamic modeling show the contours of the Ural, Kazakhstan, Central West Siberian, Altai-Sayan, and Yenisei fold systems beneath the sedimentary cover of the West Siberian Plate, as well as the 3D distribution and the Phanerozoic geodynamic environments of paleoplates, sutures, regional shear zones, and relict basins.
