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.

This list contains mineral synonyms, varieties and polytypes. The list is divided into groups:

• Introduction • (Main synonyms)
• A • B • C • D • E • F • G • H • I • J • K • L • M • N • O • P–Q • R • S • T • U–V • W–X • Y–Z

For recognised minerals see list of minerals (complete)

• Abbreviations:
  • "*" – discredited (IMA/CNMNC status).
  • "?" – questionable/doubtful (IMA/CNMNC, mindat.org or mineralienatlas.de status).
  • ^N – published without approval of the IMA/CNMNC.
  • ^I – intermediate member of a solid-solution series.
  • ^H – hypothetical mineral (synthetic, anthropogenic, etc.)

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.

• 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, Ag₄SeS, 2.BA.55): it might be two solid solution series, a monoclinic ‘acanthite-like’ series (from Ag₂S - Ag₂S_0.4Se_0.6), and an orthorhombic ‘naumannite-like’ series (from Ag₂S_0.3Se_0.7 - Ag₂Se).

Controversial chemical formulas (IMA Master List)

(and/or possible "analytical" artifacts)

• Claraite (IMA1981-023) 05.DA.30 (IMA formula: Cu²⁺₃CO₃(OH)₄·4H₂O), 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.

• Cosalite (Y: 1868) 02.JB.10 (IMA formula: Pb₂Bi₂S₅). It might have copper as essential constituent (AM Clark, MH Hey (1993) Hey's mineral index: mineral species, varieties and synonyms), ().

• The general structural formula for cosalite can be expressed as: Cu_xAg_{(i + s)}Pb_{[8–2s–0.5(x + i)]}Bi_{(8 + s)}S₂₀.

• Kobeite-Y (Y: 1950) 04.DG.05, the original analytical determinations contain between 14.91% and 17.08% ZrO₂ with only 1.99% and 1.59% SiO₂ 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.

• Mackinawite (Y: 1963) 02.CC.25 (IMA formula: (Fe,Ni)_1+xS (x = 0-0.07)), sulfide anion (atoms per formula unit, apfu) might be too low due to analytical losses.

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.
