Geochemical Features, Distribution PGE, Genesis Ultramafitov and Chromite ores Ospinsko-Kitoyskogo, Haranurskogo Massives (East Sayan)
A subject genesis of dunite-harzburgite complex and chromitites of Ospinsko- Kitoyskiy, Haranurskiy massives was considered on basis of data chemical composition chromspinelides, distribution of PGE in those rocks. They have fractionated PGE patterns with enrichment of Os, Ir, Ru and depletation of Rh, Pt, Pd. A two geochemical type of PGE distribution: [Ru-Ir-Os] [Pt-Pd- Au] was emplaced in chromitites. Local enrichment of Pt, Pd, Au is caused remobilization PGE during metasomatic in chromitites.
