Abstract
As a result of a comprehensive mineralogical and geochemical study of the Vladimirskoye gold deposit (Eastern Sayan), the authors for the first time established gold-bismuth-sulfosolic mineralization, unique to the southeastern part of the Eastern Sayan. The existence of various Bi, Pb, and Ag sulfosalts in ores, native bismuth and silver, which form specific geochemical associations and mineral accretions, indicates the complex genesis of ores and the involvement of polymetallic melts in the concentration and redistribution of gold and silver. The formation of ores is associated with the interaction of embedded collisional granitoids with rocks of the Sialic Archaean-Early Proterozoic basement of the Gargan block. The process of granitoid intrusion was accompanied by remobilization of matter and the appearance of a series of shear deformations at the accretion-collision stage (490-420 Ma) of the restructuring of the active continental margin. The concomitant high-temperature metamorphism of the amphibolite facies affected the redistribution and concentration of ore components.
