Аннотация

The Devonian Rudniy intrusion located on the Tsagaan-Shuvuut ridge (NW Mongoliaiss) is the only one of the numerous small gabbroid intrusions surrounding the Tuva depression known to contain magmatic sulfide Ni-Cu-PGE mineralization. The sulfide mineralization is confined to a prolonged narrow ultramafic horizon as disseminated blebs, which are zoned and composed of pyrrhotite, pentlandite, chalcopyrite and cubanite. The intrusion is of interest because it is a small body that solidified quickly and therefore the sulfide blebs are interpreted to keep a record of the geochemical behaviour of chalcophile elements from the crystallization of a sulfide melt in a closed system. Using LA-ICP-MS and ICP-MS analyses the concentrations of chalcophile and platinum group elements in the base metal sulfides (BMS) were measured. This allowed us to calculate partition coefficients and mass balances of PGEs in base metal sulfides.
