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 MARCH 2022
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 Bi2TeO6⋅2H2O to Bi2TeO6⋅nH2O (0 ≤ n ≤ ⅔), 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).
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.
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.
