Исследования показали, что кора данного района имеет гетерогенное строение, причем поднятия имеют различное строение коры, что свидетельствует о различном их происхождении.</p></abstract><trans-abstract xml:lang="en"><p>The results of density modeling of the structure of the tectonosphere through the Antarctic sector of the South Atlantic Ocean along profiles stretching from the Falkland Plateau to the Mozambique Ridge and crossing a series of uplifts and ridges separated by deep-sea basins are presented. Studies have shown that the crust of this region has a heterogeneous structure, and the uplifts have a different structure of the crust, which indicates their different origin.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Южная часть Атлантического океана</kwd><kwd>тектоносфера</kwd><kwd>двумерное плотностное моделирование</kwd><kwd>подводные поднятия</kwd><kwd>строение коры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>the southern part of the Atlantic Ocean</kwd><kwd>tectonosphere</kwd><kwd>2D density modeling</kwd><kwd>underwater uplifts</kwd><kwd>structure of the crust</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Российского научного фонда проект № 22- 27-00110.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Булычев А.А., Кривошея К.В., Мелихов В.Р., Зальцман Р.В.
