(Sb,As)S

System:OrthorhombicLustre:Metallic
Hardness:3
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.
