Abstract
The deep structure of the West Siberian Plate and its folded surroundings has been imaged in geoscience transects based on geophysical surveys (DSS, ECWM, CMP profiling, seismic tomography, gravity, magnetic, geothermal, MTS, VES, etc.) 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 orogenic 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.
