The Age of the Epithermal Gold–Silver Mineralization at the Kubaka Deposit (omolon Cratonic Terrane, Northeast Russia): Geological and Isotopic-Geochronological (u–pb, 40ar/39ar) Constraints

Geological, structural and mineralogical facts describing the intersection of Paleozoic ore veins with carbon and Mezozoic veins in the Kubaka gold-silver deposit in the Omolon craton terrane are presented. The totality of the above observations does not allow limitation of the age mineralization by Upper Carboniferous based on isotope-geological studies, as V.V.Akinin et al. (2020) did on ore and rock samples selected in one geological exposure of ore body in opencast mine of the Tsokolny zone.
