Correspondence: Marco Pasero (marco.pasero@unipi.it)

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.
