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

NOMENCLATURE/CLASSIFICATION PROPOSALS APPROVED IN JANUARY 2022

Revised formula for lithiomarsturite, LiCaMn3Si5O14(OH)

In the IMA List of Minerals the chemical formula of lithiomarsturite is given as LiMn2+2Ca2Si5O14(OH). However, a crystal structure study carried out on holotype material (Am. Mineral., 75, 409–414, 1990) clearly shows that Ca is hosted at the 7-fold coordinated M4 site (M4Ca1.00), whereas Mn is the dominant constituent at the three 6-fold coordinated sites: M1Mn1.00, M2(Mn0.77Ca0.23) and M3Mn1.00. Accordingly, the end-member formula should be written as LiCaMn3Si5O14(OH). This formula matches the formula of the related mineral marsturite, NaCaMn3Si5O14(OH). This is an executive decision taken by the officers of the IMA-CNMNC.

IMA 21-I: A proposed correction to the formula of rouvilleite

Proposal 21-I is accepted, and the formula of rouvilleite is changed from Na3CaMn2+(CO3)3F to Na3Ca2(CO3)3F.

IMA 21-J: Redefinition of angastonite as an amorphous mineral

Proposal 21-J is accepted, and angastonite is redefined as an amorphous mineral species, with the ideal formula CaMgAl2(PO4)2(OH)4⋅7H2O.

IMA 21-K: Grandviewite, Cu3Al2(SO4)(OH)10H2O: proposal for its redefinition

Proposal 21-K is accepted, and grandviewite is redefined as a hydrated copper-aluminum hydroxy-sulfate, having the ideal formula Cu3Al2(SO4)(OH)10⋅H2O (Z = 2) and a triclinic symmetry, with space group P $\overline 1$, a = 6.002(3), b = 10.54(3), c = 11.249(8) Å, α = 72.1(2), β = 81.6(6), γ = 86.1(8)°.

IMA 21-L: Discreditation of luinaite-(OH), (Na,)(Fe2+,Mg)3Al6(BO3)3Si6O18(OH)4, a mineral species of the tourmaline supergroup

Proposal 21-L is accepted, and luinaite-(OH) is discredited. This monoclinic tourmaline-type species, with a simplified composition (Na,)(Fe2+,Mg)3Al6(BO3)3Si6O18(OH)4, was approved with IMA number 2009-046. It is now considered a structurally similar polymorph of schorl, since it only differs in terms of a slight structural distortion from the typical trigonal tourmaline structure.
