Received: 03 Aug 2023 – Published: 18 Aug 2023

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.

3 Nomenclature/classification proposals approved in June 2023

3.1 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 A₂M1₂M2₂M3(PO₄)₄X₂(H₂O)₁₀ • 4H₂O, where A = K, H₂O; M = Mg, Mn²⁺, Al, Fe³⁺, Ti; and X = O, OH, F. The following species belong to the group: paulkerrite, mantienneite, benyacarite, pleysteinite, and hochleitnerite.

4 Nomenclature/classification proposals approved in July 2023

4.1 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 $A_{4}^{VI} B^{IV} B_{2} (T$ 1O₄)₂(T2O₄)₂Y₂. 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). Invariably in all of them A = Pb, ^IVB = Zn, T2 = P, and Y = (OH).
