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 web site.

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

Symbol for raydemarkite

The correct symbol for the new mineral raydemarkite (IMA No. 2022-015) is ryd, and not rdy, as given in CNMNC Newsletter 68.

NOMENCLATURE/CLASSIFICATION PROPOSALS APPROVED IN OCTOBER 2022

Triphylite group

The triphylite group is established; it includes seven mineral species: triphylite, lithiophilite, heterosite, purpurite, simferite, karenwebberite and natrophilite. Sicklerite and ferrisicklerite have been discredited. Simferite has been redefined as LiMg(PO4).

NOMENCLATURE/CLASSIFICATION PROPOSALS APPROVED IN NOVEMBER 2022

IMA 22-F: Holotype redefinition for donnayite-(Y)

Proposal 22-F is accepted. Re-examination of donnayite-(Y) type specimens showed that the original description contains data collected on two different phases with simplified formulae NaCaSr3Y(CO3)6⋅3H2O and Na2Sr2YCe(CO3)6⋅3H2O. The latter corresponds to the recently approved species alicewilsonite-(YCe) (IMA 2020-055). Donnayite-(Y), with the ideal formula NaCaSr3Y(CO3)6⋅3H2O, was found in only one specimen - CMNMC 39396 - out of seven housed at the Canadian Museum of Nature, 240 McLeod St, Ottawa, ON K2P 2R1, Canada. This specimen has become the holotype of donnayite-(Y).

IMA 22-G: Establishment of the mckelveyite group

Proposal 22-G is accepted, and the mckelveyite group is established. Seven minerals belong to the group: alicewilsonite-(YCe), alicewilsonite-(YLa), bainbridgeite-(YCe), donnayite-(Y), ewaldite, mckelveyite-(Y), and weloganite. Mckelveyite group minerals are carbonates with the general formula A3B3(CO3)6⋅3H2O, where A = Na, Ca, Y+HREE, Zr, and B = Sr, Ba, LREE. Their structure is based on two alternating layers with larger B cations forming one layer and smaller A cations A forming another. Different order-disorder modifications are known resulting in triclinic, monoclinic and trigonal minerals with essentially the same structure.

IMA 22-H: Redefinition of bystrite

Proposal 22-H on bystrite is accepted. The mineral bystrite was first described as a trigonal cancrinite-related phase with the simplified formula Ca(Na,K)7(Al6Si6O24)(S32–)1.5⋅H2O. Initially, two bystrite varieties were distinguished: (i) K-rich and Cl-deficient, and (ii) Cl-rich and K-deficient. The latter mineral has been subsequently approved as a separate mineral species, sulfhydrylbystrite, with the formula Na5K2Ca(Al6Si6O24)S52–(HS)–. The crystal structure of the presumed Cl-rich and K-deficient bystrite variety shows that this mineral is isostructural with sulfhydrylbystrite and is its analogue with Cl– instead of (HS)– in cancrinite cages, and Na+ at the site that is predominantly occupied by K+ in sulfhydrylbystrite. The ideal formula of bystrite is consequently redefined as Na7Ca(Al6Si6O24)S52–Cl–.

Establishment of the kristiansenite group

The proposal to establish the kristiansenite group is accepted. The group includes three mineral species: kristiansenite, with formula Ca4Sc2Sn2(Si2O7)2(Si2O6OH)2, silesiaite, with formula Ca4Fe3+2Sn2(Si2O7)2(Si2O6OH)2, and kozłowskiite, with formula Ca4Fe2+Sn3(Si2O7)2(Si2O6OH)2.
