The information given here is provided by the IMA Commission on New Minerals, Nomenclature and Classification for comparative purposes and as a service to mineralogists working on new species.

Each mineral is described in the following format:

Mineral name, if the authors agree on its release prior to the full description appearing in press

Chemical formula (ideal formula)

Mineral symbol

Type locality

Full authorship of proposal

E-mail address of corresponding author

Relationship to other minerals

Crystal system, Space group; Structure determined, yes or no

Unit-cell parameters

Strongest lines in the powder X-ray diffraction pattern

Type specimen repository and specimen number

Citation details for the mineral prior to publication of full description

Citation details concern the fact that this information will be published in the Mineralogical Magazine on a routine basis, as well as being added month by month to the Commission's web site.

It is still a requirement for the authors to publish a full description of the new mineral.

NO OTHER INFORMATION WILL BE RELEASED BY THE COMMISSION

NOMENCLATURE/CLASSIFICATION PROPOSALS APPROVED IN AUGUST 2022

Nomenclature of polymorphs and polysomes

New guidelines for the nomenclature of polymorphs and polysomes have been approved by the CNMNC:

  • – Polymorphs with different crystal systems are distinguished by the prefixes cubo- (cubic), hexa- (hexagonal), tetra- (tetragonal), trigo- (trigonal), ortho- (orthorhombic), clino- (monoclinic), and anortho- (triclinic).

  • – Polymorphs with different crystal systems but showing a pseudosymmetry should show the prefix “pseudo-”.

  • – Polymorphs with the same crystal system but different space groups are distinguished by the prefix “para-”. If three or more polymorphs show the same crystal system but different space groups, the space group notation may be added as a suffix, but such a nomenclature should be avoided if possible.

  • – Polymorphs with the same space group are distinguished by the prefix “para-”.

  • – Minerals with polymorph suffixes but with different chemical compositions cannot be considered as true polymorphs, so we recommend using the prefix “meta-”, which indicates a close but significantly different chemical composition.

  • – Polysomatic symbols have to be placed as a suffix, which indicates the number and types of modules which alternate in the structure as in the högbomite supergroup, or as prefixes as in the sartorite homologous series.

These recommendations have to be applied for future new mineral proposals, but the modifications of historical and well-established names have to pass through the CNMNC for approval. In order to be consistent with the new guidelines, 25 mineral names were modified: domeykite-β becomes trigodomeykite, fergusonite-(Y)-β becomes clinofergusonite-(Y), fergusonite-(Ce)-β becomes clinofergusonite-(Ce), fergusonite-(Nd)-β becomes clinofergusonite-(Nd), ice-VII becomes cubo-ice, roselite-β becomes anorthoroselite, sulfur-β becomes clinosulphur, mertieite-II becomes mertieite, mertieite-I becomes pseudomertieite, uranophane-α becomes uranophane, uranophane-β becomes parauranophane, gersdorffite-P213 becomes gersdorffite, gersdorffite-Pa3 becomes paragersdorffite, gersdorffite-Pca21 becomes orthogersdorffite, betalomonosovite becomes paralomonosovite, lammerite-β becomes paralammerite, nováčekite-I becomes hydronováčekite, nováčekite-II becomes nováčekite, halloysite-7Å becomes halloysite, halloysite-10Å becomes hydrohalloysite, metauranocircite-I becomes metauranocircite, taimyrite-I becomes taimyrite, uranocircite-II becomes uranocircite, andorite IV becomes quatrandorite, and andorite VI becomes senandorite.

NOMENCLATURE/CLASSIFICATION PROPOSALS APPROVED IN SEPTEMBER 2022

Voting proposal 22-E: Redefinition of braggite and vysotskite

The proposal 22-E is accepted. The ideal formula for braggite is redefined as PdPt3S4. The ideal formula for vysotskite is redefined as PdS. The ideal formula of cooperite (PtS) remains as currently given in the IMA List of Minerals.

Uranotungstite: revised formula

Recently, a paper has been published [Am. Mineral., 107, 1709–1716 (2022)], in which the chemical formula of uranotungstite is revised based on its crystal structure determination. From these data, collected on the type material, it is shown that the species is not Fe2+-dominant, as in the original description [Tschermaks Mineral. Petrogr. Mitt., 34, 25–34 (1985)], but Ba-dominant. Consequently, in agreement with the new chemical and structural data obtained on this mineral and with the dominant constituent rule, the formula of uranotungstite is modified from (Fe2+,Ba,Pb)(UO2)2(WO4)(OH)4⋅12H2O to Ba(UO2)2W2O8(OH)2⋅H2O. This is an executive decision taken by the CNMNC officers.
