The Heterogeneous Structure of the Lithosphere of the Antarctic Sector of the South Atlantic According to the Results of Density Modeling

The results of density modeling of the tectonosphere structure in the Antarctic sector of the South Atlantic Ocean are presented. The modeling was carried out along the profiles stretching from the Falkland Plateau to the Mozambique Ridge and crossing a series of submarine rises and ridges separated by deep-sea basins. Studies show that the crust of this region has a heterogeneous structure and the crust underlying the rises is of a different structure, indicating different origins of the respective rises.
