Platinum-group minerals from the Kambalda nickel deposits, Western Australia

Economic Geology, 1986
The relative abundance, compositional variability, and geologic occurrence of platinum-group minerals have been determined by a study of samples from a number of geologic environments in the Kambalda nickel deposits. These results have been integrated with findings from a previous study by Hudson and Donaldson (1984) of platinum-group minerals in ...

Platinum-group-mineral inclusions in chromitites from the Oman ophiolite

Bulletin de Minéralogie, 1986
Des minéraux du groupe du platine (PGM) ont été trouvés en inclusion dans des chromitites alumineuses du sud du complexe ophiolitique d'Oman. Contrairement aux autres complexes, on n'y trouve que des laurites (RuS2). Toutes sont primaires, fréquemment associées à un petit silicate (ou même incluses dedans), ce qui semble caractéristique de ce complexe.

Mineralogy of platinum-group minerals in the Witwatersrand, South Africa

Economic Geology, 1976
Approximately 80 percent of the platinum-group mineral grains in the Precambrian Witwatersrand conglomerate reefs are (Ir, Os, Ru) alloys. Osmium, iridosmine, osmiridium, and iridium are most abundant; rutheniridosmine, ruthenosmiridium, and ruthenian iridium are less abundant. Zoned grains are common, with Os-rich cores enclosed by (Ir, Pt)-rich outer

Platinum Group Minerals of Ranomena chromitite, Tamatave district, Madagascar

2010
Madagascar is rich in chromite deposits scattered through the Archean terranes. The main ore districts are, from North to South, Befandriana, Andriamena and Tamatave. Platinum Group Minerals (PGMs) were detected as inclusions in chromite grains as well as in the chromitite matrix in the Ranomena deposit, belonging to the Tamatave chromite district. The
