in bold: grandfathered, IMA accepted, renamed and redefined (with IMA approval) minerals,
in normal letters: minerals published without IMA approval, questionable minerals, polytypes


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
GROUP = a name used to designate a group of species
N = Mineral published without approval of the CNMNC
Q = Questionable mineral
H = Hypothetical mineral (synthetic, anthropogenic, etc.)
D = Discredited by the CNMNC
Poly = Polytype
