COMPOSITION AND MORPHOLOGY OF CRYSTALS OF PLATINUM GROUP MINERALS FROM PLACERS OF THE SOUTH URALS
Crystals of platinum group minerals (PGMs) of the Os–Ir–Ru and Pt–Fe systems from placer deposits of the South Urals are zonal and relatively homogenous in composition and can contain inclusions of PGE sulfides, arsenides, sulfarsenides, and antimonides. The crystals are characterized by idiomorphic...

| Summary: | Crystals of platinum group minerals (PGMs) of the Os–Ir–Ru and Pt–Fe systems from placer deposits of the South Urals are zonal and relatively homogenous in composition and can contain inclusions of PGE sulfides, arsenides, sulfarsenides, and antimonides. The crystals are characterized by idiomorphic, compromise growth, and shear surfaces. Compromise growth surface of the PGM crystals with rock-forming minerals is evidence of their simultaneous crystallization in primary magma. |
