Pt Content of Cu-Ni Deposits and Ore Occurrences in the Stanovoi Ni-Bearing Province (Far East, Russia)

摘要

Data on the Pt content in Cu-Ni deposits and ore occurrences of the Stanovoi Ni-bearing province of the Upper Amur Region are reported. Description and comparative analysis of the deposits and ore occurrences of the Pt-bearing Cu-Ni ores have been carried out taking into account new data on the ore geology, geochemistry, and material composition. We have described the formation prerequisites, forecast, and search criteria for large deposits of Pt-bearing Cu-Ni ores in the Upper Amur Region: the geotectonic and structural position, deep structure, formational features, magmatism of the mineralization period, hydrothermal alterations of the rocks, mineral and geochemical assemblages, PGM typomorphism, etc. This paper emphasizes the considerable potential of the Upper Amur Cu-Ni ores in relation to the complex of useful mineral resources such as gold, PGEs, sulfur, and cobalt.
