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:
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. © Thomas Witzke (2023) |
