“…They supposedly formed in middlelate Devonian, probably as a result of back-arc lithospheric extension, and have remained the principal depocenters ever since. As shown by the seismic refraction data [57,58,135] and results of crustal modeling [94], these basins, in their deepest parts, may be floored by exhumed mantle and/ or old oceanic lithosphere.…”

“…Early ideas about its geology were summarised by Shipilov and Tarasov [146], and later by Drachev et al [26]. Recently, more regional MCS lines were released for publication [58,92,93,103,172], which provide a better basis for geological interpolations across this still sparsely studied part of the Eurasian Arctic.…”

“…Generally the basin is fairly well studied seismically and there are five offshore wells that resulted in the discovery of the large Leningranskoe and Rusanovskoe gas condensate fields in the late 1980s, and the Victory oil field in 2014. Summaries of the South Kara geology can be found in Shipilov and Tarasov [146], Stoupakova et al [155], Ivanova et al [58], Nikishin et al [104], and Nikishin [105].…”

“…MCS data reveal a series of SW-NE trending grabens and half-grabens beneath thick post-extension sedimentary cover [58,104,105,175]. Since the sedimentary graben infill has not been tested by drilling, the age of rifting is unconstrained.…”

The vast Eurasian Arctic epicontinental shelf and adjoining mainland has a very complex structure and tectonic history as a result of a series of continent-continent collisions, accretion of terranes and crustal extension phases during Neoproterozoic and Phanerozoic times. Significant parts of major Eurasian fold belts extend far north into the Arctic below thick infill of post-orogenic sedimentary basins, where their architecture remains highly disputed. Large Eurasian Arctic sedimentary basins formed as a result of orogenic collapse, back-arc extension, or intracontinental extension associated with the breakup of the Laurussia, Laurasia, Pangea and Eurasia supercontinents. There are over 40 sedimentary basins of variable age and genesis which are thought to bear significant undiscovered hydrocarbon resources in the region. This article reviews the current state-of-knowledge of Eurasian Arctic tectonics and highlights questions that remain to be addressed. The overall focus is on the Russian sector of the Arctic being less known to a broad geoscience community.

15We present, summarize and discuss the lithosphere structure and evolution of the wider Kara Sea region, based on compilation and integration of geophysical and geological data. Regional 17 transects are constructed at both crustal and lithospheric scales based on the available data and a 18 regional 3D model. The transects, which extend onshore and into the deep oceanic basins are used 19 to link deep and shallow structures and processes, as well as to link offshore and onshore areas. 20The study area has been affected by numerous orogenic events: (1) Precambrian-Cambrian 21 (Timanian), (2) Silurian-Devonian (Caledonian), (3) Latest Devonian-earliest Carboniferous 22 (Ellesmerian/Svalbardian), (4) Carboniferous-Permian (Uralian), (5) Late Triassic (Taimyr, Pai Khoi, 23 Novaya Zemlya), (6) Paleogene (Spitsbergen/Eurekan). It has also been affected by at least three 24 episodes of regional-scale magmatism, so-called large igneous provinces ( North Atlantic (Paleocene-Eocene transition). Additional magmatic events occurred in parts of the 27 study area in Devonian and Late Cretaceous times. 28Within this geological framework, basin development is integrated with regional tectonic events and 29 stages in basin evolution are summarized. We further discuss the timing, causes and implications of 30 basin evolution. Fault activity is related to regional stress regimes and reactivation of pre-existing 31 basement structures. Regional uplift/subsidence events are discussed in a source-to-sink context and 32 related to their regional tectonic and paleogeographic settings. 33 34 The location of our lithosphere-scale transects with respect to gravity and magnetic 113 anomalies are shown in figure 3. The free-air gravity field (Fig. 3a) is rather smooth across (Fig. 3a). The magnetic anomaly map (Fig. 3b) shows the characteristic 122 linear sea-floor spreading anomalies of oceanic basins Gaina et al., 2009; 123 Jokat et al., 2016). In the continental part magnetic anomalies reflect a heterogeneous 124 basement both onshore and offshore (Barrére et al., 2009(Barrére et al., , 2011Marello et al., 2010Marello et al., , 2013 The most prominent feature in the depth to basement map (Fig. 4a) Ivanova et al., 2011;Sakoulina et al., 2015Sakoulina et al., , 2016.
