PGE distribution and mineralization Total PGE concentration in 9 chromitites samples ranges from 242 to 992 ppb and is about 2.5 to 5.5 times higher than in serpentinized peridotites. The all chromitites have enrichment Pd (78-903 ppb). It is unusual for chromitites. There is no obvious correlation between PGE abundance and chromite composition. All samples has positive correlation among the pairs Os-Ir (R₂-0.79), Ir-Ru (R2=0.71), Os-Ru (R2=0.64). Palladium has no correlation with another elements. Chondrite-normalised PGE patterns of Ulan-Sar'dag chromitites display average (Os+Ir+Ru)/(Rh+Pt+Pd) ratios typical of Cr-rich chromitites formed in the mantle section of supra-subduction zone ophiolites In most cases, PGE patterns are characterized by a consistent positive anomaly in Ru, and a negative anomaly in Pt.
