摘要：

The quantitative processing of gravimetric data is performed and the 3D density model is calculated for the southern part of the Russian margin of Eurasian continent. Based on the density model, new patterns of disjunctive tectonics at different depth levels are revealed and the position of the region at the global tectonic level is shown. It is established that the transition zone is an integrated lithospheric structure of the northeastern orientation, in which there are mantle blocks with the boundaries corresponding to the borders of depressions and major tectonic objects. The data obtained may be applied for refinement of the deep structure and paleogeodynamics of the studied area.
