The anorthosite complexes and related rock types of the Indian Precambrian shield are primarily associated with either cratons or mobile belts. They were metamorphosed under amphibolite to granulite facies conditions._x000D_
The major rock types are chromite-bearing meta-anorthosites, amphibolites, basic granulites, pink granites and gneisses. This study was carried out on chromitite bearing samples from Sittampundi Anorthosite Complex (SAC), Tamil Nadu, to evaluate the nature and textural settings of platinum-group minerals (PGM), using state-of-the-art technology. The structure and petrology of SAC were well studied by earlier workers (Subramanian, 1956), but only scanty data on geochemical, petrology and mineralogy of PGM are available. The mineralogy of the samples is dominated by chromite (>70 mass per cent), plagioclase (An90) and chlorite-actinolite with orthopyroxene (En85). Details of the petrological evolution of the Sittampundi complex will still have to be studied further, but indications of magma replenishment at the level of chromite formation and the elevated PGE values associated with the chromitite samples make the Sittampundi complex a promising target for future exploration activity.
