In the Early Triassic period, the continental plateau in the territory of the modern Kurgan region, similar in type of geological structure to the Putorana, Deccan, Parana, Karru, Maranhao, Tunguska syneclise plateaus, experienced an intense influence of the processes of regional rifting, which had a global distribution, as a result of which a whole system of extended graben rifts was formed. Within the territory under consideration, precipitation-compensated immersion occurred in the Late Permian-Triassic time (lasting about 80 million years), fading, but continuing throughout the Mesozoic and Cenozoic era them under the weight of overlapping sediments and in connection with the periodic activation of tectonic processes in the graben rifts themselves during their "geological" life. Sea boreal waters from the north of the West Siberian Plate penetrated through these narrow straits into the Kurgan Trans-Urals. Erosion processes as a result of erosion of the continental plateau that existed at that time formed the "remnants" of the cover low-potassium basalts. Their detailed study makes it possible to clarify the sedimentation conditions that existed within the studied territory, and the proximity of the geological structure to the volcanogenic sedimentary formations of the Permian-Triassic age of the Rogozhnikovo-Lyamin zone indicates a significant oil and gas potential of this complex of deposits. The commonality of the tectonic structure and development of the studied regions with the main part of Western Siberia (Triassic rifting) allows us to count on the discovery of hydrocarbon deposits here of a typical sedimentary rock basin structure in traditional oil and gas complexes. It is necessary to carry out detailed geological exploration work on this promising complex of deposits in the very near future.
