Stibioenargite

Formula:
Cu3(Sb,As)S4
Lustre:
Metallic
Hardness:
3
Crystal System:
Orthorhombic
Name:
Named as the Sb-analogue of enargite.
Described by Strunz (1957), not approved by the IMA in 1959.
The empirical formula, Cu3Sb0.75As0.25S4, would correspond to the Sb-analogue of enargite. However, the material is probably only Sb-bearing enargite.
The most Sb-rich enargite was found to have the composition Cu3As0.8Sb0.2S4 (Pósfay & Buseck, 1998).
May be considered a hypothetical orthorhombic polymorph of famatinite.
