Railsback's Some Fundamentals of Mineralogy and Geochemistry A table of systematic mineralogy IV: numbers of minerals Minerals consisting of uncharged Minerals consisting of cations Minerals consisting of cations bonded to atoms (i.e., in bonded to single anions negatively-charged radical groups 2- 2- elemental state) (no radical groups or complex ions) (i.e., to complex ions like CO3 or AsS3 ) Fluoborates Ferruccite (NaBF ) Fluorides 32 Fluosalts: 6 4 Fluorite (CaF2) Fluosilicates Hieratite (K2SiF6) Halides Chlorides 75 ("Group VII -ides") Halite (NaCl) (and thus minerals Bromides with 1- anions) Bromargyrite (AgBr) 4 alide anions Iodides h 3 Negative charge in Iodargyrite (AgI) mineral comes from Silicates Vanadates Arsenates Sulfites Oxides Borates Chromates Selenates Arsenites Carbonates Niobates Antimonates Selenites Hematite (Fe O ) Oxysalts: 2 3 Nitrates Molybdates Tellurates Antimonites 255 2700 Phosphates Tantalates Iodates Tellurites Sulfates Tungstates Native elements Calcite (CaCO3) Sulfur (S) Sulfides Sulfarsenates Sulfovanadates Diamond (C) "Group VI -ides" Galena (PbS) Sulfosalts: Sulfogermanates Sulfarsenites Copper (Cu) (and thus minerals Sulfantimonates Sulfantimonites Pyrargyrite 138 250 (Ag SbS ) 90 with 2- anions) Sulfostannates Sulfobismuthites 3 3 Seleniosalts: Only 31 elements occur Selenides 37 Selenioantimonates Permingeatite as native minerals. The Achavalite (FeSe) 2 Seleniobismuthites (Cu3SbSe4) number above includes VI offrom elements Group anions Tellurisalts: Volynskite comes mineral in charge Negative polymorphs (e.g., dia- Tellurides 34 Telluribismuthites mond, graphite, chaoite, Altaite (PbTe) 1 (AgBiTe2) and lonsdaleite) and naturally occurring "Group V -ides" Nitrides Osbornite (TiN) 4 alloys. (and thus Number of minerals known in each category minerals Phosphides 37 The number shown for oxides does not Barringerite (Fe,Ni) P 3 with 2 include minerals that are solely hydroxides. 3- anions) Arsenides 21 Löllingite (FeAs2) Antimonides & Bismuthides The numbers shown here can be taken at face value as an indication that there Sobolevskite (PdBi) 6 are more oxysalt and oxide minerals than any other kinds. That would not be surprising, given that oxygen is the most abundant element in Earth's crust. Carbides "Group IV -ides" 5 Alternately, the numbers shown here can be taken to reflect the greatest human Moissanite (SiC) access to oxidizing environments at Earth's surface, and our inability to sample (and thus minerals of anions from comes Silicides the reducing environments in Earth's deep interior to any significant extent. Group IV Group IV and V elements with 4- anions) 4 Negative charge in mineral Gupeiite(Fe3Si) As of 2004, a total of about 4100 minerals had been been formally recognized by the International Mineralogical Association.
