Present-day structure of Wrangel Island was formed during two main stages of Mesozoic-Cenozoic deformation. The general fold-thrust structural grain of the island, characterized by northern vergence and complicated by NW-trending right-lateral strike-slip faults, originated in the post-Triassic. Mesostructural data indicate a near-meridional orient...
The South Chukchi Basin separates the late Mesozoic Chukotka Fold Belt from the Wrangel Arch and represents the northwestern continuation of the Hope Basin of the United States sector of the Chukchi Sea, which is filled with middle Eocene-Quaternary nonmarine, marine, and lacustrine rocks. The main stages of South Chukchi Basin development in the C...
The newly obtained data on the West Kamchatka complexes, together with the results published previously, allowed us to reach
some conclusions regarding the Cenozoic kinematics in the eastern part of the Sea of Okhotsk region. The Cenozoic stress fields
of submeridional-NW-SE trend were reconstructed. These results may provide independent evidence f...

using the continuous seismoacoustic profiling method. In accordance with the previous standpoint, two Pleistocene deltaic
complexes formed in the Enotaevian and Mangyshlakian time are defined i...
The Russian sector of the Eastern Arctic is characterized by large basins with thick sedimentary filling, primarily on the shelf and continental slope of the seas of the Arctic Ocean. A number of geological, geophysi-cal, and geochemical features point to a hydrocarbon potential. At the same time, the age and composition of the sedimentary infill o...
The near-Laptev part of the Eurasian basin is the area of transition from modern spreading to intraplate rifting. We propose an approach to the construction of a 3D model of the basement of the Laptev Sea part of the Eurasian basin based on the linkage of all currently available geological and geophysical data. The structure of the acoustic basemen...

The criteria of petroleum potential of a sedimentary basin are the features that characterize the evolution of a hydrocarbon system as a geological unit. There are basic and additional criteria of oil and gas potential. Without basic criteria, the functioning of the hydrocarbon system and consequent petroleum field formation is impossible. Addition...
—Until recently, the sedimentary cover age and composition of the marginal North Kara Basin (northern part of the Kara Sea, Russian Arctic) remained uncertain because of the absence of direct data from parametric and exploration wells. Taking into consideration the absolute importance of these issues for understanding the regional geology of the Ar...
—The correlation between the sedimentologic characteristics of the Upper Triassic deposits of Wrangel Island and the Chukchi Peninsula (Chukotka) is discussed.

The presented article is devoted to the actual problem of regional geology — the reconstruction of the history of geological development of the Upper Paleozoic-Triassic complex in the southern part of the North Caspian. Understanding of evolution is one of the necessary conditions for improving the reliability of predicting the geological objects c...
Structural styles (or structural paragenesis in Russian literature) in the sedimentary
cover result from tectonic processes that took place during the
basin evolution. Hydrocarbon traps within regions with a single structural
style can share similar structure and tectonic development features. This, in
turn, may determine the commonality of risk fa...
Data collected by several expeditions to the Arctic Ocean have yielded a seismic stratigraphic framework and basin fill history for the Alpha-Mendeleev Rise (AMR) and adjacent Podvodnikov, Makarov, North Chukchi, Toll, Mendeleev, Nautilus and Stefansson basins. The AMR comprises a double-sided volcanic passive margin formed in Aptian-Albian time. T...
Abstract—The U–Pb (LA-ICP-MS) dating of detrital zircons from the Upper Cretaceous Derevyannye Gory Formation in the Novaya Sibir Island revealed that tuffites and tuffaceous sandstones contain zircons widely ranging in age from Archean to Upper Cretaceous. The weighted average age of the youngest zircon population is 88 ± 1.0 Ma, which constrains...

This analysis tied together seismic stratigraphic interpretations for the shelf and the deep-water part of the ocean. The stratigraphic framework is based o...
The North Chukchi Trough depositional history was largely written by changes in direction
of sedimentary influx. In the Aptian-Cenomanian the sediments were transported from the
New Siberia – Chukotka fold and thrust belt highs. The Cenomanian extension led to the
transgression. From Cenomanian to middle Paleocene the North Chukchi Trough has
been...

The Northern, Central, and Southern zones are distinguished by stratigraphic, lithologic, and structural features. The Northern Zone is characterized by Upper Silurian–Lower Devonian sedimentary rocks, which are not known in other zones. They have been deformed into near-meridional folds, which formed under settings of near-latitudinal shortening d...
The paper presents new data on the U–Pb zircon age, as well as results of isotopic geochemical analysis, of granites and rhyolites from Wrangel Island. The U–Pb age estimates of granites and rhyolites are grouped into two clusters (~690–730 and 590–610 Ma), which imply that these rocks crystallized in the Late Neoproterozoic. Granitic rocks dated b...
