IMA Commission on New Minerals, Nomenclature and Classification (CNMNC) – Newsletter 66

Ritsuro Miyawaki, Frédéric Hatert, Marco Pasero, and Stuart J. Mills

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 and classification proposals approved in March 2022

3.1 IMA 22-A: redefinition of montanite

Proposal 22-A is accepted, and the status of montanite is changed from “Q” to “Rd”. The formula of montanite is modified from Bi2TeO62H2O to Bi2TeO6nH2O (0 n2/3), and two neotypes, preserved at the Natural History Museum in London, UK, are created. Type localities are Highland, Montana, USA (sample BM 85116), and David Beck's Mine, North Carolina, USA (sample BM 1985, Nev336).

3.2 IMA 22-B: redefinition of moxuanxueite

Proposal 22-B is accepted, and the ideal end-member formula of moxuanxueite (IMA no. 2019-100) is modified from Na2Ca5Zr(Si2O7)2F4 to NaCa6Zr(Si2O7)2OF3.

3.3 IMA 22-C: arrojadite group nomenclature – sigismundite reinstated

Proposal 22-C is accepted, and arrojadite-(BaFe) is renamed sigismundite, according to the rule for the preservation of historical names.
