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.

(Y: 1938) might be a calcian
gadolinite. :*
ClinotyroliteN (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 - Ag2S0.4Se0.6), and an orthorhombic 'naumannite-like' series (from Ag2S0.3Se0.7 - Ag2Se).
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% ZrO2 with only 1.99% and 1.59% SiO2 respectively. The chemical formula (IMA version: ) doesn't contain Zr. ::*Pavel Kartashov: ::*If no Zr and U>Th then euxenite group,
polycrase ::*If no Zr and U0 \le x \le 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: :*

Cosalite (Y: 1868) 02.JB.10 (IMA formula: Pb2Bi2S5).

Chlormayenite can be found in nature.
Suspended (IMA status) :*(IMA2000-026) : 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 ().
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.
