“…However, from a structural point of view, it is not unlikely that a succession of Early Jurassic sedimentary rocks could be preserved within the crater, even if they have been removed from the surrounding area. In an interpretation of the structural geology of the impact area, Kolodyazhnyi () interpreted the so‐called “Coptomict Gravelite” (redeposited lithic breccia and melt‐bearing breccia underlying the Kovernino Formation) as being Early Jurassic in age, and the Kovernino Formation as Bajocian–Bathonian following Masaitis and Pevzner (). The palynological assemblage from the unit of redeposited breccia analyzed herein suggests that deposition took place in a freshwater environment during the Sinemurian–Pliensbachian, although a single specimen of Leiosphaeridia sp.…”

The Puchezh‐Katunki impact structure, 40–80 km in diameter, located ~400 km northeast of Moscow (Russia), has a poorly constrained age between ~164 and 203 Ma (most commonly quoted as 167 ± 3 Ma). Due to its relatively large size, the Puchezh‐Katunki structure has been a prime candidate for discussions on the link between hypervelocity impacts and extinction events. Here, we present new 40Ar/39Ar data from step‐heating analysis of five impact melt rock samples that allow us to significantly improve the age range for the formation of the Puchezh‐Katunki impact structure to 192–196 Ma. Our results also show that there is not necessarily a simple relationship between the observed petrographic features of an impact melt rock sample and the obtained 40Ar/39Ar age spectra and inverse isochrons. Furthermore, a new palynological investigation of the postimpact crater lake sediments supports an age significantly older than quoted in the literature, i.e., in the interval late Sinemurian to early Pliensbachian, in accordance with the new radioisotopic age estimate presented here. The new age range of the structure is currently the most reliable age estimate of the Puchezh‐Katunki impact event.

“…В настоящее время появляется все больше данных о высокой тектонической подвижности Восточно-Европейской платформы (ВЕП), которая выражена, в частности, в развитии широких и протяженных тектонических зон. Эти внутриплитные нарушения характеризуются длительным периодом развития, полистадийными деформациями в различных динамических условиях, сложным и неоднородным строением в разрезе и вдоль простирания [Kolodyazhnyi, 2014[Kolodyazhnyi, , 2015[Kolodyazhnyi, , 2018. Предполагается, что тектонические процессы, связанные с формированием этих зон, играли важную роль при пе рераспределении УВ в пределах самих нарушений и в областях их динамического влияния.…”

Tectonical and development features of the central part of the Volga-Ural anteclise and the Sura-Kama (SK) shear zone are considered in connection with the distribution patterns of oil fields. Based on the geological and structural data, it is found that the SK zone is a deep fault of a heterogeneous structure, which has signs of the long-term multistage development. At the plate stage, the SK zone developed under kinematic inversion and subsequent transpression and transtension deformations. We propose a model showing that during the transtension stages, deformations in the SK zone contributed to the primary migration of hydrocarbons in the Devonian domanic formations and their secondary redistribution. Within the SK zone, permeability was increased, and the zone itself acted as a concentrator of these formations in local decompression structures. Fault structures in the SK zone closed during the transpression stages; their reservoir properties were decreased; and hydrocarbons were squeezed predominantly in the lateral direction along the reservoirs in the area of dynamic unloading. At the eastern termination of the SK zone, the unique Arlan oil field was formed, wherein hydrocarbons were accumulated in conditions of alternating stresses between the sectors compensating shear displacements at the flanks of the zone. The unique Romashkinsky oil field was formed in the apical part of the South Tatar arch during its long-term uplifting and decompression, which contributed to progressive migration and accumulation of hydrocarbons from the transpression sector of SK zone. The proposed structural-dynamic model and ideas about compression – decompression regularities of hydrocarbon redistribution in the shear zones can be used for prediction and detection of new deposits. In particular, the dynamic analogues of the Arlan oil field in the east part of the SK zone can be found within the poorly studied western flank of this zone.

The Sura-Kama zone (SKZ) complicates the central area of the Volga-Ural anteclise and extends sublaterally from the Sura River basin towards the Kama River at a distance of 700-750 km. Based on the analysis of geological-geophysical data and structural studies, a model for the tectonic structure and the evolution of the SKZ is developed. This is a deep tectonic fault that shows the features of long-term polystage development. During the latest Cimmerian-Alpine period of tectonic reactivation, the SKZ rep resented a zone of strike slip and consecutive manifestation of early transpressional right lateral strike slip dislocations that changed to left lateral strike slip displacements under transtension settings as a result of kinematic inversion. Features of the heterogeneous structure of the SKZ are revealed. The segments formed by the system of strike slip duplexes are alternated along the strike by the principle of rotation-fold and "domino" structures. The particular models of evolution of these segments are proposed by the examples of the widely known Karlin, Tetyushin, and Lower Kama dislocations. It is assumed that kinematic inversion and compression-decompression phenomena on the flanks of the SKZ, as well as the tectonic environments in the area of its dynamic influence were highly important for the development of the processes of migration and redistribution of hydrocarbon components.
