Using of rheologic gravity models of the Far East lithosphere in the tectonics, geodynamics, and metallogeny
Results of gravity modelling of rheological inhomogeneities of tectonic media (a comparative estimation) onto the crust and upper mantle of the Russian Far East are generalised. The tectonosphere of this region up to depth of 150 km from the Earth's surface includes two rigid layers (the crystal crust and lower lithosphere) and three layers of the lowered viscosity (volcanic-sedimentary, viscous subcrustal and astenospheric). Spatial interrelations of rigid tectonic plates and viscous layers dividing them are using at the deep structural mapping and paleodynamic researches of lithospheric plates, fold-thrusted systems, volcanic belts, rifts and structures of the central type of the plume nature. Real applications of the rheological gravity models are illustrated at long-term forecasts of seismic danger and the study of the space arrangement laws of ore deposits.
