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.

Consequently, since polarite has historical priority, borishanskiite is discredited. Columbite supergroup The columbite supergroup has been established. It includes 39 oxide minerals based on the general stoichiometry M : O = 1 : 2, and structurally characterized by zig-zag chains of edge-sharing octahedra. The supergroup is divided into the following: ixiolite group, wolframite group, samarskite group, columbite group, and wodginite group. A number of actions were taken on some of the minerals belonging to the supergroup; the most relevant among them are as follows: – polycrase-(Y) has been discredited, as it is identical to euxenite-(Y), and the latter mineral has historical priority. https://doi.org/10.1180/mgm.2022.93 Published online by Cambridge University Press – the old “ixiolite” has been redefined and now results in two distinct mineral species: ixiolite-(Mn2+), with end-member for2+ mula (Ta2/3Mn2+ 1/3)O2, and ixiolite-(Fe ), with end-member for2+ mula (Ta2/3Fe1/3)O2. The type locality for both is Skogsböle, Kimito Island, Finland. Revised formula for shkatulkalite, Na2Nb2Na3Ti (Si2O7)2O2(FO)(H2O)4(H2O)3 In the IMA List of Minerals the chemical formula of shkatulkalite is given as Na10MnTi3Nb3(Si2O7)6(OH)2F⋅12H2O. However, a crystal structure study carried out on holotype material (Can. Mineral., 60, 493–512, 2022) clearly shows that Mn is not the dominant constituent at any crystallographic site. Accordingly, the end-member formula should be written as Na2Nb2Na3Ti (Si2O7)2O2(FO)(H2O)4(H2O)3. This formula matches the general formula of the minerals of the lamprophyllite group of the seidozerite supergroup, to which shkatulkalite belongs. This is an executive decision taken by the officers of the IMA– CNMNC.
