# List of minerals (synonyms)

The International Mineralogical Association (IMA) is the international group that recognises new minerals and new mineral names. However, minerals discovered before 1959 did not go through the official naming procedure although some minerals published previously have been either confirmed or discredited since that date.

### Doubtful procedures
#### Unnamed minerals, controversial discreditations

   * Wolframoixiolite, a W-bearing variety of ixiolite, 04.DB.25; possibly a separate species.
      * Scandian ixiolite (of von Knorring)$^N$, a Nb-bearing variety of ixiolite, 04.DB.25; possibly a separate species.
      * Scandian ixiolite (of Bergstol)$^N$, a Sc-bearing variety of ixiolite, 04.DB.25; possibly a separate species.
   * Ktenasite (Y: 1950) 07.DD.20, possibly a mineral group, under review (Leverett et al., 2009–2011).
      * Unnamed (Zn-analogue of Ktenasite)$^N$.
      * Unnamed (Co-analogue of Ktenasite)$^N$.
      * Mg- or Cd-bearing varieties are also known.
   * Loparite-(Ce) (Y: 1923) 04.CC.35, possibly a mineral group
      * Mitchell R H, Burns P C, Chakhmouradian A R (2000) The crystal structures of loparite-(Ce), The Canadian Mineralogist 38, 145-152.
      * Zubkova, N. V., Arakcheeva, A. V., Pushcharovskii, D. Y., Semenov, E. I., & Atencio, D. (2000). Crystal structure of loparite. Crystallography Reports, 45(2), 210-214.
   * Calciogadolinite-Y? (Y: 1938) might be a calcian gadolinite.
   * Clinotyrolite$^N$ (monoclinic), both minerals might belong to a mineral group since tyrolite was shown to be monoclinic (pseudo-orthorhombic).
   * Yttromicrolite-(Y) within the framework of nomenclature of Hogarth (1977): discreditation was not made by proper way (in the course of defamation of Crook, 1982).
   * Pimelite* (Y: 1800, 1938) a nickel dominant smectite, is under review. Associations: nickel-bearing talc, yellow green nickeloan nontronite, red brown hematite stained nontronite, bright white montmorillonite.
   * Tetranatrolite (discredited in 1999): might be identical to gonnardite, discreditation procedure apparently done without actually working on the type specimen or on any identified tetranatrolite itself.
   * Yftisite-(Y) (discredited in 1987): but apparently the cell parameters are known (Balko & Bakakin, 1975).
   * Buserite (IMA1970-024): dehydrates to birnessite, known synthetic compound.
   * Zincobotryogen: it is discredited (IMA1967 s.p.) but its crystal structure has been solved (space group 14).
   * Strontioborite: it is discredited (IMA1962 s.p.) but its crystal structure has been solved (space group 4).
   * Aguilarite (Y: 1944, Ag$_4$SeS, 2.BA.55): it might be two solid solution series, a monoclinic 'acanthite-like' series (from Ag$_2$S - Ag$_2$S$_{0.4}$Se$_{0.6}$), and an orthorhombic 'naumannite-like' series (from Ag$_2$S$_{0.3}$Se$_{0.7}$ - Ag$_2$Se).

#### Controversial chemical formulas (IMA Master List)

    (and/or possible "analytical" artifacts)
   * Kobeite-Y (Y: 1950) 04.DG.05, the original analytical determinations contain between 14.91% and 17.08% ZrO$_2$ with only 1.99% and 1.59% SiO$_2$ respectively. The chemical formula (IMA version: (Y,U)(Ti,Nb)$_2$(O,OH)$_6$) doesn't contain Zr.
      * Pavel Kartashov:
      * If no Zr and U>Th then euxenite group, polycrase
      * If no Zr and U<Th then aeschynite group, priorite, blomastrandin.
   * Divalent sulfide. Mackinawite (Y: 1963) 02.CC.25 (IMA formula: (Fe,Ni) $_{1+x}$S ($0\leq x\leq 0.07$)), sulfide anion (atoms per formula unit, apfu) might be too low due to analytical losses.
   * Pseudo monovalent mercury, mindat.org changed the chemical formulas: there is mercury(II) and (dimercury) [Hg-Hg] now.
    Notes:
   * Claraite (IMA2016-L, IMA1981-023) 05.DA.30 (IMA formula: Cu$^{2+}$$_3$CO$_3$(OH)$_4$·4H$_2$O), but after U. Kolitsch it has essential As and S.
      * Kolitsch, U. & Brandstätter, F. (2012): 1743) Baryt, Chalkophyllit und Clarait vom Pengelstein bei Kitzbühel, Tirol. P. 149. in Niedermayr, G. et al. (2012): Neue Mineralfunde aus Österreich LX. Carinthia II, 202./122., 123-180.
      * Putz, H., Lechner, A. & Poeverlein, R. (2012): Erythrin und Clarait vom Pichlerstollen am Silberberg bei Rattenberg, Nordtirol. Lapis, 37 (1), 47-52; 62.
      * New chemical formula: (Cu,Zn)$_{15}$(CO$_3$)$_4$(AsO$_4$)$_2$(SO$_4$)(OH)$_{14}$·7H$_2$O.
   * Cosalite (Y: 1868) 02.JB.10 (IMA formula: Pb$_2$Bi$_2$S$_5$). It might have copper as essential constituent (AM Clark, MH Hey (1993) Hey's mineral index: mineral species, varieties and synonyms), (Zak, L.; Megarskaya, L.; Mumme, W. G. (1992). "Rezbanyite from Ocna de fier (Vasko): a mixture of bismuthinite derivatives and cosalite". Neues Jahrbuch für Mineralogie. Monatshefte 1992: 69–79.).
      * The general structural formula for cosalite can be expressed as: Cu$_x$Ag$_{(i+s)}$Pb$_{[8–2s–0.5(x+i)]}$Bi$_{(8+s)}$S$_{20}$.
   * Mayenite (IMA2013-C, IMA1963-016): it can not be found in nature. Mayenite (stabilized by moisture) can be found in cement industry chemistry. Chlormayenite can be found in nature.

#### Suspended (IMA status)

   * (IMA2000-026) (Mn,Li)$_4$(Ta,Sn)$_4$(Ta,Nb)$_8$O$_{32}$: IMA approval status is suspended, but it was incorrectly stated as approved in Grice, J.D. & Ferraris, G. (2001).
   * (IMA1989-012), zhangpeishanite (of Shen), unnamed (cordylite-like (Ca□Ba$_2$Ce$_4$[CO$_3$]$_8$F$_2$).

#### Grandfathered (IMA valid species)

* Chrysocolla? (Theophrastus, 315 BC), it's suggested that it is mixture of spertiniite (Cu(OH)$_2$) and chalcedony or opal, it has similarities with copper-bearing allophane.
* Loranskite-(Y) (Y: 1899) it might be a fictional mineral, the type material is probably a mixture of euxenite and zircon.
