Gold mineralization of gold-quartz vein-type is confined to narrow shear zones in the metabasic volcanic suite of the Mangalur Greenstone Belt. The dominant sulphide phase associated with the gold mineralization is pyrrhotite-pyrite assemblage followed by arsenopyrite, chalcopyrite and sphalerite in the decreasing order of abundance. Gold occurs in native state and within quartz.
