Fig. 3. Density section of the earth's crust along profile 3910, obtained from the simulation of gravitational anomalies. 1 - observed gravitational anomalies (reduction in free air); 2 - calculated gravitational anomalies; 3 - density, g / cm3; 4 - numbers of pseudo-wells, according to which numerical modeling was performed; 5 - the boundary between the continental-type riftogenic crust and the oceanic-type crust (2019)
