About FischesseriteHide

Specific Gravity:
9.05 (Calculated)
Crystal System:
Named by Johan Zdenek, Paul Picot, Roland Pierrot, and Milan Kvacek in 1971 in honor of Raymond Fischesser (1911-1991), French mineralogist and crystallographer, Director of the National School of Mines, Paris, France.
Black equant crystals and grains, frequently as microscopic intergrowths.

Classification of FischesseriteHide


2 : SULFIDES and SULFOSALTS (sulfides, selenides, tellurides; arsenides, antimonides, bismuthides; sulfarsenites, sulfantimonites, sulfbismuthites, etc.)
B : Metal Sulfides, M: S > 1: 1 (mainly 2: 1)
A : With Cu, Ag, Au

4 : AmBnXp, with (m+n):p = 2:1

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