| description | Studies of recent geodynamics have been conducted by the Institute of the Earth’s Crust, SB RAS since 1998. Present-day crustal deformations are monitored at the geodynamic GPS polygon established by the Laboratory of Recent Geodynamics in the Mongol-Baikal region. Original methods and techniques using specialized equipment are applied to research intra-continental tectonic deformation and have already provided original scientific results. Independent data are received concerning the onset and character of processes of neotectonic activation and the state of stresses and deformation of the crust in the southern part of Siberia and in Mongolia. A model of the Late Cenozoic and contemporary geodynamics of the Mongol-Siberian mobile area is proposed. With application of GPS geodesy methods, quantitative parameters of present-day horizontal movements and deformations are determined for Central Asia and a part of the Far East at different scale levels. Present-day velocities of extension of the Baikal rift are estimated, and parameters of rotation of the Amur plate relative to Eurasia are calculated. Data on long-term and contemporary deformation are subject to comparative analyses. The Laboratory develops studies of present-day and historical seismicity in relation to processes of contemporary faulting in active tectonic zones of inter-plate boundaries and diffusive activation of subactive intraplate territories. The first results are obtained in studies of local crustal deformation by methods of satellite radar interferometry and ground polygonometry. Jointly with other institutes of SB RAS, the Laboratory conducts instrumental studies of interaction between the lithosphere and the ionosphere. Looking further ahead, the main scientific fields and prospects of the Laboratory are highlighted. |
