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 SEPTEMBER 2021

An end-member formula for humite, Mg7(SiO4)3F2

The humite polysomatic series consists of a set of minerals with the general formula n[Mg2(SiO4)]⋅Mg(OH,F)2, with n = 1, 2, 3, or 4. The valid species and their corresponding chemical formulae, taken from the current IMA List of Minerals, are as follows:

(n = 1)

Norbergite, Mg3(SiO4)F2

(n = 2)

Chondrodite, Mg5(SiO4)2F2

Hydroxylchondrodite, Mg5(SiO4)2(OH)2

(n = 3)

Humite, Mg7(SiO4)3(F,OH)2

(n = 4)

Clinohumite, Mg9(SiO4)4F2

Hydroxylclinohumite, Mg9(SiO4)4(OH)2

The only species without an end-member formula is humite, Mg7(SiO4)3(F,OH)2, which has both fluorine and hydroxyl within the same brackets. As in the whole series a rootname without a prefix is used for the fluorine end-member, whereas the same rootname with the prefix ‘hydroxyl-’ is used for the hydroxyl end-member, the formula Mg7(SiO4)3F2 has to be assigned to the mineral humite. This is an executive decision taken by the officers of the IMA-CNMNC.

Renaming of gismondine

Following the report of the Zeolite subcommittee, after the approval of the new mineral IMA 2021-043 – gismondine-Sr (see this Newsletter), ‘gismondine’ becomes a series name. Accordingly the mineral previously known as gismondine is renamed gismondine-Ca.

IMA 20-F: Chabournéite group

Proposal 20-F is accepted, and the chabournéite group is established. The group includes the minerals chabournéite, protochabournéite, dalnegroite, shimenite and dewitite. All members of this group are triclinic, space group P $\overline 1$, with the exception of dalnegroite, which has space group P1.

The ideal formulae of protochabournéite and chabournéite are revised as follows:

Protochabournéite – Tl4-xPb2+2xSb20-x-yAsyS34 (with 0.02 ≤ x ≤ 0.34, 5.71 ≤ y ≤ 6.69).

Chabournéite – AgzTl8-x-zPb4+2xSb40-x-yAsyS68 (with 0.00 ≤ x ≤ 0.40, 16.15 ≤ y ≤ 19.11, 0.04 ≤ z ≤ 0.11).

IMA 21-D: Redefinition of beraunite and discreditation of eleonorite

Proposal 21-D is accepted. The formula of beraunite is revised as Fe3+6(PO4)4O(OH)4⋅6H2O, based on new EMPA, Mössbauer and SCXRD data obtained on type material. Eleonorite is discredited, as it is identical to beraunite.

IMA 21-E: Redefinition of minyulite

Proposal 21-E is accepted, and the formula of minyulite is redefined as KAl2(PO4)2F⋅4H2O, based on new EMPA data obtained on holotype material, which confirmed that the mineral is (OH)-free and has F as a species-forming constituent.
