About DuranusiteHide

grey black, translucent dark red in very tiny splinters
2 - 2½
Specific Gravity:
4.50 (Calculated)
Crystal System:
Named by Zdenek Johan, Claude Laforêt, Paul Picot and Jean Feraud in 1973 for the type locality, the small community of Duranus, France.
A rare black sulphide mineral.

Layered structure, related to that of arsenolamprite. The unit cell has 8 As and 2 S atoms. There are two types of corrugated layers - As2 and As2S - stacked along [010].

Classification of DuranusiteHide

Approval Year:

2 : SULFIDES and SULFOSALTS (sulfides, selenides, tellurides; arsenides, antimonides, bismuthides; sulfarsenites, sulfantimonites, sulfbismuthites, etc.)
F : Sulfides of arsenic, alkalies; sulfides with halide, oxide, hydroxide, H2O
A : With As, (Sb), S

1 : AmXp, with m:p > 3:1

3 : Sulphides, Selenides, Tellurides, Arsenides and Bismuthides (except the arsenides, antimonides and bismuthides of Cu, Ag and Au, which are included in Section 1)
7 : Sulphides etc. of V, As, Sb and Bi
