General Notes
Bartelke (1976) cited Geier (1973/74) as recording that millerite could be detected in mixed ore by means of reflected light microscopy, a view reiterated by Pinch and Wilson (1977). However, Lombaard et al. (1986) consider the occurrence of millerite questionable.
Hughes (1987) lists millerite as a supergene sulphide replacing Ni-rich carrollite.
