MINERAL CLASSIFICATION / SYSTEMATIK der MINERALE

           based on E.H. Nickel & M.C. Nichols (2009), H. Strunz & E.H. Nickel (2001),
           revised by Thomas Witzke (2022)



2. SULFIDES and SULFOSALTS
(Sulfides, Selenides, Tellurides, Arsenides, Antimonides, Bismuthides, Sulfarsenites, Sulfantimonites, Sulfbismuthites, etc.)


2.M: Sulfarsenates. AsS4 tetrahedra


2.MA. Simple Sulfarsenates
 
2.MA.005. Enargite group
 
Enargite Cu2CuAsS4 orth., Pnm21 G
Petrukite (Cu,Ag)2(Fe,Zn)(Sn,In)S4 orth., Pnm21 IMA 1985-052

 
2.MA.010. Luzonite group
 
Luzonite Cu3AsS4 tetr., I42m G
Famatinite Cu3SbS4 tetr., I42m G
Permingeatite Cu3SbSe4 tetr., I42m IMA 1971-003
Briartite Cu2(Fe,Zn)GeS4 tetr., I42m IMA 1965-018
Zincobriartite Cu2(Zn,Fe)GeS4 tetr., I42m IMA 2015-094
Barquilite Cu2(Cd,Fe)GeS4 tetr., I42m IMA 1996-050

 
2.MA.015. Fangite
 
Fangite Tl3AsS4 orth., Pnma FOTO A



 
 
2.MB. Sulfarsenates with additional S
 
2.MB.005. Billingsleyite
 
Billingsleyite Ag7AsS6 cub., P213 A



 
 

G = Grandfathered minerals: original description preceded the establishment of the CNMNC in 1959, and generally regarded as a valid species
A or IMA No. = Minerals approved by the CNMNC
Rd = Redefinition of the mineral approved by the CNMNC
Rn = Renamed with approval by the CNMNC
Q = Questionable mineral



Classification principles:
Subdivision of the Sulfide etc. subclass "2.M: Sulfarsenates" into 2.JA Simple Sulfarsenates; 2.JB Sulfarsenates with additional S.

Further classification:
2.MA.: Simple Sulfarsenates: ...
2.MB.: Sulfarsenates with additional S: Only one mineral.


To distinguish from classical Strunz numbering, on hierarchical "group" level, a numbering with 3 digits is used, like "2.MA.005. Enargite group", instead of 2 digits (like "2.MA.05.") in the Strunz system.
