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 APRIL 2022

Mckelveyite-(Y): end-member formula

In the current IMA List of Minerals the chemical formula of mckelveyite-(Y) is given as NaBa3(Ca,U)Y(CO3)6⋅3H2O. Minor uranium (ca. 0.15 apfu) was detected in the original description of the mineral [Am. Mineral. 50 (1965), 593–612]. However the ideal formula, for stoichiometric constraints, can not contain any U. A crystal structure study of mckelveyite-(Y) [Can. Mineral. 46 (2008), 195–203] clearly shows that the Ca site is occupied by calcium only. Therefore uranium does not occur, or might occur as a subordinate cation; in either case it should be omitted from the chemical formula of mckelveyite-(Y), which becomes NaBa3CaY(CO3)6⋅3H2O. This is an executive decision taken by the officers of the CNMNC.
