“…Both the Carboniferous and Permian strata overlie, with a prominent angular unconformity at their base, Ordovician to Devonian strata. These facts may indicate compressional deformation in earliest Carboniferous time, possibly related to the Ellesmerian orogeny in the Canadian Arctic, which is supported by recent structural observations and sediment provenance study [128].…”

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.

“…The composite Svyatoi Nos-Oloy Magmatic belt was formed during closure of the South Anyui Ocean, resulting in the collision of the Arctic Alaska-Chukotka Superterrane with the Siberian Margin [5,65]. The Late Jurassic-Early Cretaceous volcanic and volcaniclastic rocks are consistent with the characteristics of a continental arc, while the Aptian-Albian granitoids in the Svyatoi Nos Cape area and Berriasian-Valanginian granodiorites of the Oloy branch reflect either the final Magmatic phase of the Magmatic arc or the incipient continental collision and formation of the Novosibirsk-Chukotka orogeny (e.g., [16,18]).…”

“…In the Mesozoic, several arc Magmatic belts formed during closure of the Oymyakon Ocean and the resulting collision of the Kolyma-Omolon Superterrane and Siberia, including the Main (Kolyma), Uyandina-Yasachnaya, Northern, and Transverse Magmatic belts (e.g., [1][2][3][4][5][6][7][8][9][10][11][12] and references therein). To the north (in present-day coordinates), the Svyatoi Nos-Oloy and New Siberian-Chukotka Magmatic belts formed during closure of the South Anyui Ocean and formation of the Novosibirsk-Chukotka orogenic belt (e.g., [2,3,5,6,[11][12][13][14][15][16][17][18], and references therein). The coeval Magmatic belts also formed to the south along the A number of coeval Late Mesozoic sedimentary basins of varying sizes formed across NE Asia in response to this tectonic and magmatic activity, but their geological histories are poorly understood due to the lack of geological constraints on their tectonic settings, paleogeographic affinities, and sedimenatry provenance.…”

We performed U-Pb dating of detrital zircons collected from Middle–Upper Jurassic strata of the Sugoi synclinorium and Cretaceous rocks of the Omsukchan (Balygychan-Sugoi) basin, in order to identify their provenance and correlate Jurassic–Cretaceous sedimentation of the south-eastern Verkhoyansk-Kolyma orogenic belt with various magmatic belts of the north-east Asia active margins. In the Middle–Late Jurassic, the Uda-Murgal magmatic arc represented the main source area of clastics, suggesting that the Sugoi basin is a back-arc basin. A major shift in the provenance signature occurred during the Aptian, when granitoids of the Main (Kolyma) batholith belt, along with volcanic rocks of the Uyandina-Yasachnaya and Uda-Murgal arcs, became the main sources of clastics deposited in the Omsukchan basin. In a final Mesozoic provenance shift, granitoids of the Main (Kolyma) batholith belt, along with volcanic and plutonic rocks of the Uyandina-Yasachnaya and Okhotsk-Chukotka arcs, became the dominant sources for clastics in the Omsukchan basin in the latest Cretaceous. A broader comparison of detrital zircon age distributions in Jurassic–Cretaceous deposits across the south-eastern Verkhoyansk-Kolyma orogen illustrates that the Sugoi and Omsukchan basins did not form along the distal eastern portion of the Verkhoyansk passive margin, but in the Late Mesozoic back-arc basins.
