KINEMATICS OF THE EARTH’S SURFACE IN WEST SIBERIA FROM THE RESULTS OBTAINED BY INSTRUMENTAL TECHNIQUES^* Available to Purchase

Two maps, “Map of velocities of present-day vertical movements of the Earth’s crust” and “Map of present-day kinematics of the Earth’s surface in West Siberia”, were first compiled for the whole territory of West Siberia. The data on relevelling in central and northern West Siberia permitted us to generalize spatial and temporal regularities of distribution of regional present-day vertical movements. To solve some geodynamic problems, we propose to use the “Map of present-day kinematics of the Earth’s surface in West Siberia”, where not only velocities of the present-day vertical movements of the Earth’s crust (PVMEC) but also surface structures of absolute and relative uplifts, zones of intense downwarping and faulting becoming active in the present-day stage are shown. According to formal signs of the PVMEC velocities of anomalies, we have determined the kinematic type of the Earth’s crust strain in the zone of these faults. Also we have shown a tendency of vertical movements in the Jurassic, Lower Cretaceous, Neogene-Quaternary, and Recent periods.
