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

OTHER ISSUES

Revised formula for peprossiite-(Ce)

In the IMA List of Minerals the current formula of peprossiite-(Ce), (Ce,La)(Al3O)2/3B4O10, is not charge-balanced. Following the approval of the new mineral peprossiite-(Y) (IMA 2024-046; this Newsletter), and the re-examination of the latest analytical data on holotype peprossiite-(Ce) [American Mineralogist, 85, 586–593 (2000)], it was agreed to modify the formula to CeAl2(B3.67Si0.33)O10.67.

Revised mineral symbols

After the approval of the new mineral nioboixiolite-(Fe3+) (IMA 2024-057; this Newsletter), for which the symbol Nbix-Fe3+ is adopted, it was agreed that all minerals including an extended Levinson suffix in their name should contain the same suffix in the symbol. Accordingly, the symbol for three newly approved minerals is modified as follows:

Ixiolite-(Fe2+) – new symbol Ix-Fe2+ (old symbol Ix-Fe changed)

Ixiolite-(Mn2+) – new symbol Ix-Mn2+ (old symbol Ix-Mn changed)

Nioboixiolite-(Mn2+) – new symbol Nbix-Mn2+ (old symbol Nbix-Mn changed)

This is an executive decision taken by the CNMNC officers.
