..., Krasnoyarskiy kray, and the second pertains to the Miass placer zone, Chelyabinsk oblast, in the southern Urals. The platinum-group element (PGE) mineralization in both cases is mostly (at least 80%) represented by alloy minerals in the system Ru–Os–Ir, in the order of occurrence osmium, ruthenium and iridium...

... a ), and on the Fe–Ir binary from Swartzendruber ( 1984 ). The tentative delineation of phase fields in the ternary shows that minerals plotting in the area of the ε-phase are separated from hexaferrum and ruthenium by two miscibility gaps. Clearly, minerals whose analyses plot within the Ru–Os–Fe ternary...

...) and shows a chondrite-normalized PGE pattern with a slightly positive slope, with enrichment in Pt and Pd relative to Os and Ir. Ruthenium and Rh show positive and negative peaks, respectively. In agreement with the PGE distribution, the following platinum-group minerals (PGM) have been found: laurite ((Ru...
