... Sucesso platinum, from 0.10 to 0.30% (mass), by electron-microprobe analysis, are too elevated compared to ours and may be an artifact of the electron microprobe. The compositional differences are graphically shown in the multi-element plot of Figure 2 . Ruthenium, Rh, Os, and Ir are remarkably...

..., 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...
