Relevance. The geological history of the Semizbai depression, which was formed at the beginning of the Mesozoic and developed during the Cenozoic, has been studied. The relatively stable platform tectonic regime in the Triassic led to the territory peneplanation and the development of an areal weathering crust. The sources of the formation of the terrigenous sequence were the products of physical weathering of the basement granitoids. Objective. Uranium-containing products of chemical weathering entered the stratum in the form of solutions and were absorbed by its clayey rocks. During the activation of the tectonic regime at the beginning of the Jurassic, the faults in the basement served as channels for the entry of uranium-bearing hydrothermal solutions into the pore layers of the terrigenous sequence. Methods. According to geological studies primary ore bodies were formed from these solutions in sandy layers. When the depression subsided, as deposits accumulated, the thickness of the stratum, consisting of water-bearing and water-resistant rocks, increased. In the thickness, the conditions of an artesian basin were created, where interstratal and infiltration underground waters circulated. In the elision regime, uranium compounds were squeezed out of clayey rocks, which, together with primary hydrothermal ores, fell into aquifers. Results and practical significance. Water flows redeposited uranium compounds and formed the hydrothermal-hydrogen Semizbai uranium deposit. The presented geological model serves as the basis for choosing a rational development technology and effective reagents.
