Полученные данные позволяют соотнести время начала этапа глубоководного осадконакопления с границей эоцена и олигоцена, а не с нижним миоценом, как предполагалось ранее. Вертикальные дифференцированные движения привели к опусканию современных глубоководных впадин до абиссальных, а разделяющих их хребтов и поднятий – до батиальных глубин. Дифференцированное проседание Центрального бассейна Северного Ледовитого океана, очевидно, было парагенетично формированию региональной правосдвиговой зоны вдоль Северо-Американской границы океана от района Северной Гренландии до дельты реки Маккензи.</p></abstract><trans-abstract xml:lang="en"><p>The modern structure and morphology of the Central Arctic domain has been formed as a result of the Oligocene – Quaternary evolution stage. The neotectonic stage was triggered by the final episode of the Eurekan orogeny resulted in the formation of several complex deformation zones onshore of Canadian Arctic Archipelago, north and NE Greenland, and Svalbard, as well as offshore of the Beaufort Sea. Prior to this stage, the prototypic terrain of the Arctic Basin already comprised most of the modern morphological structures, however, it was characterized by fairly smooth local topographic relief. Ridges and plateaus were located within the distal neritic or upper bathyal zone, but the surrounding depressions occurred in the middle part of the bathyal zone. The blocky differential subsidence of the entire Arctic Basin occurred during the neotectonic stage.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Северный Ледовитый океан</kwd><kwd> сейсмические исследования</kwd><kwd> эвриканская орогения</kwd><kwd> синокеанические отложения</kwd><kwd> неотектонический этап</kwd><kwd> палеоцен-эоценовый температурный максимум</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Arctic Basin</kwd><kwd> seismic reflection data</kwd><kwd> Eurekan orogeny</kwd><kwd> synoceanic deposits</kwd><kwd> neotectonic stage</kwd><kwd> Paleocene-Eocene Thermal Maximum</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Настоящая работа выполнена в отделе сводного и обзорного геологического картографирования ВСЕГЕИ в рамках Государственных заданий Федерального агентства по недропользованию № 049-00009-18-00 и № 049-00013-19-00 за 2018 и 2019 гг.
