Published: 13 April 2022

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 (yesor 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 offull 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 thecommission’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.

3.1

Nomenclature and classification proposals approvedin March 2022
IMA 22-A: redefinition of montanite

Proposal 22-A is accepted, and the status of montanite ischanged from “Q” to “Rd”. The formula of montanite ismodified from Bi2 TeO6 ·2H2 O to Bi2 TeO6 · nH2 O (0 ≤ n ≤2/3), 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
