Published: 31 August 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)

Citation details concern the fact that this information will
be published in the European Journal of Mineralogy on aroutine 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/classification proposals approved inJune 2022
IMA 22-D: borishanskiite discredited

New analyses of the holotype sample of borishanskiite (IMA
no. 1974-010) show that this mineral is identical to polarite(IMA no. 1969-032). Consequently, since polarite has historical priority, borishanskiite is discredited.
3.2

391– Polycrase-(Y) has been discredited, as it is identical toeuxenite-(Y), and the latter mineral has historical priority.
– The old “ixiolite” has been redefined and results now in
two distinct mineral species: ixiolite-(Mn2+ ), with end2+
member formula (Ta2/3 Mn2+
1/3 )O2 , and ixiolite-(Fe ),with end-member formula (Ta2/3 Fe2+
1/3 )O2 . The type locality for both is Skogsböle, Kimito Island, Finland.
3.3

Revised formula for shkatulkalite,
Na2 Nb2 Na3 Ti(Si2 O7 )2 O2 (FO)(H2 O)4 (H2 O)3

In the IMA List of Minerals the chemical formula of shkatulkalite is given as Na10 MnTi3 Nb3 (Si2 O7 )6 (OH)2 F · 12H2 O.
However, a crystal structure study carried out on holotype
material (Can. Mineral., 60, 493–512, 2022) clearly showsthat Mn is not the dominant constituent at any crystallographic site. Accordingly, the end-member formula should
be written as Na2 Nb2 Na3 Ti(Si2 O7 )2 O2 (FO)(H2 O)4 (H2 O)3 .
This formula matches the general formula of the mineralsof the lamprophyllite group of the seidozerite supergroup, towhich shkatulkalite belongs. This is an executive decision
taken by the officers of the IMA-CNMNC.

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 chainsof edge-sharing octahedra. The supergroup is divided into
the following: ixiolite group, wolframite group, samarskitegroup, columbite group, and wodginite group. A number ofactions were taken on some of the minerals belonging to thesupergroup; the most relevant among them are as follows:
