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 Sulfides etc. subclass 2.J: Sulfosalts based on 1D derivatives of PbS/SnS archetype, i.e., on rod-type building blocks is different from Strunz 9, adapted from the sulfosalt systematics in Moëlo et al. (2008). New: 2.JA Rod-layer sub-type (boulangerite plesiotypic family); 2.JB "Cyclic" sub-type and chessboard derivatives; 2.JC Aikinite-bismuthinite homeotypic series; 2.JD Unclassified.
Further classification:
2.JA.: Rod-layer sub-type (boulangerite plesiotypic family): Order according to Moëlo et al. (2008), adapted to the Strunz 9 classification scheme.
2.JB.: "Cyclic" sub-type and chessboard derivatives: Order according to Moëlo et al. (2008), adapted to the Strunz 9 classification scheme.
2.JC.: Aikinite-bismuthinite homeotypic: Only one group.
2.JD.: unclassified: ...


Based on
Moëlo, Y. et al. (2008): Sulfosalt systematics: a review. Report of the sulfosalt sub-committee of the IMA Commission on Ore Mineralogy.- Eur. J. Mineral. 20, 7-46.


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