Составлены карты рельефа поверхности Мохо и распределения плотности в подошвенной части фундамента в Южно-Татарском и Северо-Татарском бассейнах, на основании которых сделан вывод о смене типов земной коры с юга на север и существовании межбассейнового субконтинентального блока между двумя этими бассейнами.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents the results of structural-density modeling of the southern and northern Tatar trough, performed in order to detail the features of the deep structure of the Earth’s crust and to detect hidden tectonics of the transition zone between the South Tatar and North Tatar basins. Maps have been compiled for the Moho surface relief and density distribution in the basement of the South Tatar and North Tatar basins, on the basis of which a conclusion is made about the south-north alternation of the Earth’s crust types and the existence of an interbasinal subcontinental block between these two basins.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гравиметрия</kwd><kwd>структурно-плотностное моделирование</kwd><kwd>земная кора</kwd><kwd>Татарский трог</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gravimetry</kwd><kwd>structural-density modeling</kwd><kwd>Earth’s crust</kwd><kwd>Tatar trough</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проведено в рамках госзадания Тихоокеанского океанологического института им.
