Abstract
In 2018–2020 within the Biryusinskaya dome structure (Eastern Sayan Region), during the prospecting of the «Sosnovgeologiya», the Vostochno-Stolbovoye uranium ore occurrence, localized near the small uranium deposit Stolbovoye, has been discovered. The study of the ore occurrence geological position and epigenetic transformations of the Early Proterozoic granitoids and the overlying Middle Riphean sandstone has been carried out. A conclusion about the Рre-Middle Riphean origin of the ore concentrations of uranium and their connection with the processes of the weathering crusts formation on granite and possible subsequent transformations of the ore-bearing medium and ore matter has been made.
