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 JUNE 2023

IMA 22-K-bis – Establishment of the paulkerrite group

(Ian E. Grey, Ferdinando Bosi, William G. Mumme and Stephanie Boer)

Proposal 22-K-bis is accepted, and the paulkerrite group is defined. The general formula may be written as A 2M12M22M3(PO4)4X 2(H2O)10⋅4H2O, where A = K, H2O; M = Mg, Mn2+, Al, Fe3+, Ti; X = O, OH, F. The following species belong to the group: paulkerrite, mantienneite, benyacarite, pleysteinite and hochleitnerite.

NOMENCLATURE/CLASSIFICATION PROPOSALS APPROVED IN JULY 2023

Establishment of the dongchuanite group

(Guowu Li, Ningyue Sun and Yuan Xue)

The dongchuanite group has been established. The general formula may be written as A 4VIB IVB 2(T1O4)2(T2O4)2Y 2. Currently there are the following species: dongchuanite (VIB = Zn, T1 = P), cuprodongchuanite (VIB = Cu, T1 = P), zheshengite (VIB = Zn, T1 = As), and cuprozheshengite (VIB = Cu, T1 = As). In all of them it is invariably A = Pb, IVB = Zn, T2 = P, Y = (OH).
