Received: 30 May 2022 – Published: 15 Jun 2022

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 X-ray powder 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 European Journal of Mineralogy on a routine basis, as well as being added month by month to the commission's website. 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.

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.
