Resumo
The geodynamic position of the productive Kevaktinskii and Dal’netaiginskii stratigraphic units with Au–U mineralization is considered within the Baikal–Patom highland. The Au–U specialization of rocks of the Kevaktinskaya Group results from its formation in the environments of the passive continental margin with introduction of the juvenile material related to riftogenesis and further collision, whereas the same specialization of the Dal’netaiginskaya Group is explained by exhalation activity in the back-arc spreading zone. The formation of most of the Au and U large-scale deposits within the southern environs of the Siberian Craton was controlled by Paleozoic oogenesis upon closure of the Paleoasian Ocean.
