Seven of the Middle Jurassic to Quaternary seismic sequences was identified based on interpretation of multichannel seismic data. The information about seismic stratigraphy and crustal thickness (calculated from gravity data) along the section crossing the Princess Elizabeth Trough was used for numerical modeling of the thermal regime of the lithosphere, tectonic subsidence of the crystalline basement and lithospheric stretching. Modeling shows that calculated tectonic subsidence is possible only under the assumption of crustal extension before the deposition (during the crustal doming at the early rift phase). Maximum stretching factor in the basin ranges from 1.1 to 2.0 for the period which preceded the deposition and 2.8 for the period of the rift-related deposition.</p> <p> </p><p> </p> </abstract><trans-abstract xml:lang="ru"><p>В статье рассматривается строение земной коры, сейсмостратиграфия, термическая эволюция и характер растяжения литосферы глубоководного осадочного бассейна, расположенного в троге принцессы Елизаветы на континентальной окраине Восточной Антарктиды в южной части Индийского океана. В результате сейсмостратиграфического анализа в осадочном чехле бассейна выделено 7 сейсмических комплексов, которые формировались в период от поздней ранней юры до настоящего времени. На основании данных о глубинном строении бассейна выполнено численное моделирование его термического режима и тектонического погружения. По результатам моделирования установлено изменение температуры пород с глубиной и степени растяжения литосферы в рифтовой истории бассейна. Моделирование показало, что для объяснения глубины погружения фундамента и мощности кристаллической части земной коры бассейна требуется растяжение литосферы до начала формирования осадков. Максимальная амплитуда растяжения выявлена в депоцентре бассейна, где она составляет 2.0 до начала осадконакопления и 2.8 – в период накопления рифтовых осадков.</p></trans-abstract><kwd-group xml:lang="en"><kwd>East Antarctica</kwd><kwd>Princess Elizabeth Trough</kwd><kwd>passive margin</kwd><kwd>lithosphere</kwd><kwd>rifting</kwd><kwd>crustal stretching</kwd><kwd>sedimentary basin</kwd><kwd>tectonic subsidence</kwd><kwd>numerical modeling</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Восточная Антарктика</kwd><kwd>трог Принцессы Елизаветы</kwd><kwd>пассивная окраина</kwd><kwd>литосфера</kwd><kwd>рифтогенез</kwd><kwd>растяжение земной коры</kwd><kwd>осадочный бассейн</kwd><kwd>тектоническое погружение</kwd><kwd>численное моделирование</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This work was supported by the Russian Science Foundation (project No. 16-17-10139).</funding-statement><funding-statement xml:lang="ru">Работа выполнена при поддержке Российского научного фонда (проект № 16-17-10139).</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Галушкин Ю.И Моделирование осадочных бассейнов и оценка их нефтегазоносности.
