Abstract
The first Indian occurrence of renierite, [Cu10(Cu0.09Zn0.71Fe0.15)0.15Fe4(Ge1.68V0.03-As0.27)1.98]16.93S16.08 is reported from the Cu-rich basal zone of the polymetallic deposit at Rajpura-Dariba. Optical, X-ray and electron microprobe data on the mineral are compared with those from other occurrences. A slight excess of the iron content compared with the formula Cu10(Zn1-x Cux )(Ge2-x Asx )Fe4S16 of Bernstein (1986) and noticeable differences between Cu-coefficient (in brackets) and As-coefficient are obtained. The substitution scheme in renierite may be more complicated than that suggested by Bernstein (1986), and apparently also includes the substitution Cu↔Zn ↔Fe together with As↔Ge.
