Abstract
Based on the complex interpretation of seismic and gravitу data along profile 1-SB, the parameter of weighted density was considered for different levels of the crust in Transbaikalia, Baikal region, and the Siberian Platform. The character of the distribution of weighted density in the crust emphasizes differences in the geodynamic essence of these areas. For folded regions, unlike the Siberian Platform, there is a higher contrast in the variation of weighted density in the upper layer of the consolidated crust and in the upper mantle layer.
Supporting agencies: The study was carried out within the framework of the project No. FWZZ-2022-0021 “Regional structure features of the Earth’s crust and upper mantle of platform and folded areas of Siberia, their stress-strain state according to seismological, gravimetrical and geomechanical data.
