north Eurasian lithosphere plate separated from neighboring plates by some transit zones. These zones consist of numerous crust blocks limited by active faults and interblock zones, in which maximal volumes of the seismic energy release. The examination of different geophysical fields of central Asia shows that interblock zones coincide with some anomalies in magnetic and partly gravity fields. Heat-flow values increase up to 80-100 μW/m-2 and more in interblock zones in boundaries of Hangay, Amurian, Tibet’s, and Tarim blocks as well as in some inner continental rifts. Some of heat-flow anomalies can be connected with mantle plumes under Hangay and north part of the Amurian Block. Within the central Asian transit zone the up-to-date tectonic compression distinctly predominates, while in the east Asian zone it changes partly on extension and slipping wit
