Работа основана на синтезе интерпретации региональных сейсмических профилей МОВ ОГТ 2Д и данных опробования горных пород с помощью специальных подводных аппаратов на склонах подводных гор и уступов. Поднятие представлено чередованием поднятий типа горстов и полуграбенов. В основании разрезов горстов выделяются яркие рефлекторы, которые интерпретируются как вулканиты. Разрезы полуграбенов имеют клиновидную форму в разрезе и по геометрии подобны последовательностям рефлекторов, наклоненных в сторону моря (seaward-dipping reflectors sequences (SDRs)) континентальных пассивных вулканических окраин. Опробование горных пород показало, что горсты сложены осадочными породами палеозоя, пронизанными интрузиями. На горстах выделены разрезы апта-альба с вулканитами (базальты, трахибазальты, трахиандезиты). U/Pb датирование магматических пород показало, что типичный возраст пород составляет 110–114 млн лет. Магматические меловые породы содержат цирконы с возрастами от до-барремского мезозоя до палеозоя и докембрия. Эти цирконы были захвачены базальтовой магмой при ее движении вверх. Наличие этих древних цирконов указывает на то, что поднятие Менделеева сложено континентальной корой. Предложена модель строения коры поднятия Менделеева. В основании видимого на сейсмических профилях разреза преобладают вулканиты (на горстах от базальтов до трахиандезитов, в полуграбенах в основном базальты). Верхняя и нижняя кора примерно на 20–30 % насыщена интрузиями основного состава. В основании коры выделяется высокоскоростной слой толщиной до 5 км. Предполагается, что его нижняя часть целиком представлена интрузиями типа габбро, а верхняя часть — это самая нижняя часть нижней коры, максимально насыщенная интрузиями.</p></abstract><trans-abstract xml:lang="en"><p>   The Mendeleev Rise is located in the Amerasia Basin of the Arctic Ocean. The work is based on a synthesis of interpretation of regional seismic profiles of the OGT 2D DOM and data from rock sampling using special underwater vehicles on the slopes of seamounts and scarps. The uplift is represented by alternation of highs (horsts) and half-grabens. At the base of the horst sections, bright reflectors are distinguished, which are interpreted as volcanics. Half-graben sections are wedge-shaped in section and are similar in geometry to seaward-dipping reflectors (SDRs) of continental passive volcanic margins. Rock sampling has shown that the horsts are composed of sedimentary rocks of Palaeozoic age, penetrated by intrusions. Aptian-Albian sections with volcanics (basalts, trachybasalts, trachyandesites) were identified on the horsts. U/Pb dating of igneous rocks showed that typical age of rocks is 110–114 Ma. Magmatic Cretaceous rocks contain zircons with ages ranging from pre-Barremian Mesozoic to Palaeozoic and Precambrian. These zircons were captured by basaltic magma during its upward movement. The presence of these ancient zircons indicates that the Mendeleev Rise is composed of continental crust. A model of the crustal structure of the Mendeleev Rise is proposed. The base of the section visible on seismic profiles is dominated by volcanics (on horsts from basalts to trachyandesites, in half-grabens mainly basalts). The upper and lower crust is approximately 20–30 % saturated with intrusions of basic composition. At the base of the crust, a high-velocity layer up to 5 km thick is distinguished. It is assumed that its lower part is entirely represented by gabbro-type intrusions, and the upper part is the lowest part of the lower crust, maximally saturated with intrusions.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>поднятие Менделеева</kwd><kwd>SDR</kwd><kwd>сейсмостратиграфия</kwd><kwd>U/Pb датирование возраста</kwd><kwd>Арктика</kwd><kwd>строение коры</kwd><kwd>магматизм</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Mendeleev Rise</kwd><kwd>SDR</kwd><kwd>seismic stratigraphy</kwd><kwd>U/Pb age dating</kwd><kwd>Arctic</kwd><kwd>crustal structure</kwd><kwd>magmatism</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке гранта РНФ (проект № 22-27-00160)</funding-statement><funding-statement xml:lang="en">The work was supported by a grant from the Russian Science Foundation (project No. 22-27-00160)</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">Никишин А.М., Петров Е.И., Старцева К.Ф. и др.
