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...

“…A robust tectonic model of the Amerasia Basin would yield insights into Arctic paleogeography, paleoclimate, the driving forces of the opening of the basin, and resource exploration within the dozens of circum-Arctic sedimentary basins (Shephard et al, 2013). Recently, the oceanic nature of the crust in the Canada Basin, which forms the major part of the Amerasia Basin, was revealed by refraction seismic data (Chian et al, 2016).

“…However, the nature and age of the Amerasia Basin have been debated for decades (e.g., Embry, 1990Embry, , 2000Grantz et al, 1998Grantz et al, , 2011Lane, 1997;Miller et al, 2006Miller et al, , 2017. Nevertheless, the age of the Canada Basin remains elusive, with an inferred range of 160-72 Ma from investigations on the stratigraphy and volcanism along its margins and sparse geophysical data in the basin [e.g., Alvey et al, 2008;Chian et al, 2016;Døssing et al, 2013Døssing et al, , 2017Embry,1990;Gaina et al, 2014;Grantz et al, 2011;Lane,1997;Langseth et al, 1990;Miller et al, 2006Miller et al, , 2017Taylor et al, 1981]. The roughly symmetric oceanic lithosphere about a N-S trending gravity low indicates that the Canada Basin was an E-W spreading oceanic basin.…”

The origin and history of the Amerasia basin are long-running debates, which hinder our knowledge of the Mesozoic tectonic configurations and geodynamic processes in the Arctic. This lack of knowledge is due in part to the paucity of accurate magnetic data in the ice-covered basin. Here, we identify the crustal age of the Canada Basin, a major part of the Amerasia Basin, through high-resolution deep-tow and sea-surface magnetic data. The best fit of the four pairs of magnetic lineations revealed by the high-resolution magnetic data is 139.5-128.6 Ma (or 142.4-132.8 Ma, depending on the geomagnetic polarity timescale). The crustal age provides crucial constraints on the evolution of the circum-Arctic tectonic features and generally supports the hypothesis that the opening of the Amerasia Basin is related to the subductions during the closure of the South Anyui Ocean.Plain Language Summary The Amerasia Basin of the Arctic Ocean is one of the last major puzzles of the plate reconstructions, due to the lack of age knowledge. The identification of magnetic anomalies is the routine method of acquiring the age of oceanic crust, yet floating ice in the basin makes it difficult to obtain magnetic data. We collected deep-tow magnetic data in the basin by lowering a magnetic sensor to a depth of~2,000 m, which provides high-resolution data and avoids floating ice. The identified magnetic lineations indicate the Amerasia Basin opened at 139. Ma, depending on the geomagnetic polarity timescale). The contemporaneous closure of the ancient South Anyui Ocean (~1,000 km in the south) may have provided space for the opening of the Amerasia Basin. This interpretation then generally supports the existing hypothesis that the opening of the Amerasia Basin is associated with the subduction process in the South Anyui Ocean. Nevertheless, a more sophisticated geodynamical model is still needed.

The genesis of the Amerasia Basin in the Arctic Ocean has been difficult to discern due to overprint of the Cretaceous High‐Arctic Large Igneous Province (HALIP). Based on detailed analysis of bathymetry data, new Arctic magnetic and gravity compilations, and recently published radiometric and seismic data, we present a revised plate kinematic model of the northernmost Amerasia Basin. We show that the smaller Makarov Basin is formed by rifting and seafloor spreading during the latest Cretaceous (to middle Paleocene). The opening progressively migrated into the Alpha Ridge structure, which was the focus of Early‐to‐Middle Cretaceous HALIP formation, causing breakup of the proto‐Alpha Ridge into the present‐day Alpha Ridge and Alpha Ridge West Plateau. We propose that breakup of the Makarov Basin was triggered by extension between the North America and Eurasian plates and possibly North Pacific plate rollback.
