About DufrénoysiteHide

Ours Pierre Armand Petit Dufrenoy
Dark lead-grey; dark red-brown (transmitted light)
Specific Gravity:
5.50 - 5.57
Crystal System:
Member of:
Named by Augustin Alexis Damour in 1845 in honor of Ours Pierre Armand Petit Dufrenoy [September 5, 1792 Sevran, Seine-et-Oise, France - March 20, 1857 Paris, France], Professor of Mineralogy in the École des Mines, Paris. The mineral dufrénite is also named in his honor.
Dufrenoysite-Veenite Series. Compare argentodufrénoysite.

The structure contains isolated and interconnected AsS3 pyramids, as, e.g., in case of baumhauerite, gratonite, sartorite, and seligmannite.

Classification of DufrénoysiteHide

Approved, 'Grandfathered' (first described prior to 1959)

2 : SULFIDES and SULFOSALTS (sulfides, selenides, tellurides; arsenides, antimonides, bismuthides; sulfarsenites, sulfantimonites, sulfbismuthites, etc.)
H : Sulfosalts of SnS archetype
C : With only Pb

5 : 2.5 < ø < 3

5 : Sulphosalts - Sulpharsenites and Sulphobismuthites (those containing Sn, Ge,or V are in Section 6)
6 : Sulpharsenites etc. of Pb alone

Physical Properties of DufrénoysiteHide
