Platinum-group minerals (PGM) occur as discrete inclusions in the chromite and in the associated silicates. Textural considerations suggest that the PGE chalcogenides with S and As were formed in the high-temperature magmatic stages, as part of the chromite precipitation event (primary PGM), in contrast with the native PGE, which originated during the low-temperature serpentinization of the ultramafic host of the chromitites (secondary PGM) (Torres-Ruiz, et al., 1996).
