“…( 2 An angular unconformity at the base of the rift complex is observed on some seismic lines in the area of the De Long High (Nikishin et al, 2014). This unconformity probably corresponds to the known regional unconformity on the New Siberian Islands, which lies at the base of the Aptian and is substantiated in many studies (Kos'ko and Trufanov, 2002;Kuzmichev et al, 2009Kuzmichev et al, , 2013Kos'ko et al, 2013;Nikishin et al, 2017).…”

“…On the New Siberian Islands, the collisional orogeny ended before the Mid Aptian. Upper Aptian deposits unconformably overlie the Paleozoic-Lower Jurassic folded complex with the surface marked by angular discordance (Kos'ko and Trufanov, 2002;Kuzmichev et al, 2009Kuzmichev et al, , 2013Kos'ko et al, 2013). This angular unconformity is well expressed on seismic profiles located in the area of the New Siberian Islands (Drachev et al, 2018;Nikishin et al, 2018;Nikishin et al, 2017;Nikishin et al, 2014) (Fig.…”

“…Mafic intrusion of Bel'kovsky Island yielded a late Permian-early Triassic age (252 ± 2 Ma) (Kuzmichev and Pease 2007). The structure of Bel'kovsky Island is complicated by small depressions filled with Palaeogene-Neogene sands and silts (Kos'ko et al 1985;Proskurnin et al 2012;Kuzmichev et al 2013), related to Cenozoic extension across the adjacent Laptev Shelf associated with opening of the oceanic Eurasia Basin to the north (Drachev et al 1999).…”

Abstract:In our study, we have developed a new tectonic scheme of the Arctic Ocean, which is based mainly on seismic profiles obtained in the Arctic-2011, Arctic-2012 and Arctic-2014 Projects implemented in Russia. Having interpreted many seismic profiles, we propose a new seismic stratigraphy of the Arctic Ocean. Our main conclusions are drawn from the interpretation of the seismic profiles and the analysis of the regional geological data. The results of our study show that rift systems within the Laptev, the East Siberian and the Chukchi Seas were formed not earlier than Aptian. The geological structure of the Eurasian, Podvodnikov, Toll and Makarov Basins is described in this paper. Having synthesized all the available data on the study area, we propose the following model of the geological history of the Arctic Ocean: 1. The Canada Basin formed till the Aptian (probably, during Hauterivian-Barremian time). 2. During the Aptian-Albian, large-scale tectonic and magmatic events took place, including plume magmatism in the area of the De Long Islands, Mendeleev Ridge and other regions. Continental rifting started after the completion of the Verkhoyansk-Chukotka orogenу, and rifting occurred on the shelf of the Laptev, East Siberian, North Chukchi and South Chukchi basins, and the Chukchi Plateau; simultaneously, continental rifting started in the Podvodnikov and Toll basins. 3. Perhaps the Late Cretaceous rifting continued in the Podvodnikov and Toll basins. 4. At the end of the Late Cretaceous and Paleocene, the Makarov basin was formed by rifting, although local spreading of oceanic crust during its formation cannot be excluded. 5. The Eurasian Basin started to open in the Early Eocene. We, of course, accept that our model of the geological history of the Arctic Ocean, being preliminary and debatable, may need further refining. In this paper, we have shown a link between the continental rift systems on the shelf and the formation history of the Arctic Ocean. Аннотация: На основе российских сейсмических профилей, полученных в рамках проектов Арктика-2011, Арктика-2012 и Арктика-2014, составлена новая тектоническая схема Арктического океана. Приведены ре-зультаты интерпретации многих сейсмических профилей, представлена новая сейсмостратиграфия для Арк-тического океана. Основные выводы сделаны на основе интерпретации сейсмических профилей и на базе анализа региональных геологических данных. Показано, что рифтовые системы в пределах морей Лаптевых, Восточно-Сибирского и Чукотского были образованы не раньше аптского времени. Дано описание геологиче-ского строения бассейнов Евразийского, Подводников, Толля, Макарова и других. На основе синтеза всех дан-ных получена следующая модель истории Арктического океана. 1. Канадский бассейн был образован до апт-ского времени (вероятно, в готериве-барреме). 2. В апте-альбе были крупномасштабные тектонические и магматические события: плюмовый магматизм был в районе поднятия Де-Лонга, на хребте Менделеева и в других областях. Континентальный рифтинг произошел сразу после оконча...
