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 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

NOMENCLATURE/CLASSIFICATION PROPOSALS APPROVED IN FEBRUARY 2024

Nomenclature of the ancylite supergroup

(Yanjuan Wang, Fabrizio Nestola, Zengqian Hou, Ritsuro Miyawaki, Igor V. Pekov, Xiangping Gu, Guochen Dong and Kai Qu)

The ancylite supergroup is established. Minerals of the ancylite supergroup have the general crystal chemical formula (M x3+M 2+2–x)(CO3)2[(OH)x⋅(2–x)H2O]. The supergroup is divided into the ancylite group (1 ≤ x ≤ 1.5), including eight valid species [ancylite-(La), ancylite-(Ce), calcioancylite-(La), calcioancylite-(Ce), calcioancylite-(Nd), gysinite-(La), gysinite-(Ce), gysinite-(Nd)], and the kozoite group (1.5 < x ≤ 2), including two valid species [kozoite-(La), kozoite-(Nd)].

OTHER ISSUES

Ideal formula for mackinawite

Five years ago, several chemical formulae of minerals were simplified by removing subordinate constituents, specifically minor chemical elements that were listed in parentheses after the dominating, species-defining constituent; more information on the changes to the formulae can be found in CNMNC Newsletter 50 [Mineralogical Magazine, 83, 615–620 (2019)]. The recent publication of a paper [American Mineralogist, 109, 401–407 (2024)] prompted us to modify the ideal formula of mackinawite. That mineral has been revised from (Fe,Ni)1+xS [x = 0–0.07] to FeS as the above paper showed that the composition of mackinawite corresponds to end-member FeS, with Ni, Co, and Cu present as subordinate constituents that are not included in the ideal formula. The formula of mackinawite in the IMA List of Minerals has been updated accordingly. This is an executive decision taken by the CNMNC officers.

Ideal formula for oftedalite

The chemical formula of oftedalite was reported in the 2009 Nickel–Nichols list as KSc2Be3AlSi11O30. Since the SCXRD study indicates that the T1 site is fully occupied by Si and that Al partially substitutes for Be at the T2 site, the formula was given as KSc2(Be,Al)3Si12O30 in the first release (September 2012) of the IMA List of Minerals. In December 2014 the formula of oftedalite was improperly changed to KSc2□2Be3Si12O30, which is not charge balanced. To rectify this error, the formula must be revised to K(ScCa)□2Be3Si12O30. This latter formula better matches the electron microprobe data of oftedalite from the Heftetjern pegmatite, Tørdal, Norway – the only known occurrence – which shows [Sc0.96Ca0.79Mn2+0.18Fe2+0.04Y0.03]Σ2.00 at the A site and [Be2.91Al0.09]Σ3.00 at the T2 site [Canadian Mineralogist, 44, 943–949 (2006)]. This is an executive decision taken by the CNMNC officers.
