We present the articles of the second issue of scientific journal "Mining Science and Technology" (Russia) for 2025:

Scientists have studied the geological structure of the West Siberian Oil-and-Gas Province (OGP) to establish relationships between local strike-slip dislocations of the Russko-Chaselsky Ridge and the regional Pai-Khoi–Altai shear zone. The research aimed to identify patterns of hydrocarbon accumulation associated with fault systems in this zone. Using 2D/3D seismic surveys and digital models of gravity/magnetic fields, the team analyzed crustal deformation features within the shear zone, mapping sedimentary cover and basement structures. Results show that Pai-Khoi–Altai shear zone dislocations exhibit right-lateral strike-slip morphology, forming a hierarchical system with en echelon faults and Riedel shears. In the Russko-Chaselsky Ridge, these structures interact with graben-rift systems, creating submeridional deformation zones in the platform cover and upper basement. Seismic interpretation revealed "flower structures" extending from Lower Cretaceous to Paleozoic strata, which may serve as hydrocarbon migration pathways in the West Siberian OGP. These findings improve predictions of oil/gas accumulation in fault-controlled traps.
