Occurrence of platinum group minerals in the Western Bastar Craton, Chandrapur District, Maharashtra

摘要

The occurrence of platinum group minerals (PGMs) and gold is reported in association with Fe-Ni-Cu sulphides and chromite in mafic-ultramafic rocks (gabbro-pyroxenite) of Gondpipri area in the Western Bastar Craton. These minerals are mainly moncheite and palladium moncheite and are identified using scanning electron microscope. Chemical analysis of bed-rock samples shows anomalous platinum group element values in which palladium dominates over platinum. This communication highlights the distribution of PGMs and their mineralogical association.
