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
NEW MINERAL PROPOSALS APPROVED IN JUNE 2022

NOMENCLATURE/CLASSIFICATION PROPOSALS APPROVED
IN JUNE 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.
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.
