Geodynamic background for large-scale mineralization in the southern environs of the Siberian Craton in the Proterozoic

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