Published: 3 April 2020

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;

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 fulldescription of the new mineral.
No other information will be released by the commission.

Nomenclature/classification proposals approved in
February 2020

Arctite supergroup
The arctite supergroup has been established; it currently includes nine mineral species. The supergroup is divided into
the zadovite group (alternation of tetrahedral layers and antiperovskite layers – TA) and the arctite group (alternation oftetrahedral layers and triple antiperovskite layers – TA3 ).
Fillowite group
The fillowite group has been established; it currently
includes four mineral species. The chemical formulae of the minerals of the fillowite group have been
uniformed, based on nine (PO4 ) groups pfu, as follows: fillowite, Na3 CaMn2+
11 (PO4 )9 ; johnsomervilleite,
2+
Na3 CaFe11 (PO4 )9 ; chladniite, Na3 CaMg11 (PO4 )9 ; galileiite, Na3 Fe2+ Fe2+
11 (PO4 )9 . Stornesite-(Y) has been discredited since it is equivalent to Y-bearing chladniite.
Magnetoplumbite group
The magnetoplumbite group has been established; it currently includes 11 mineral species. Minerals of the magnetoplumbite group have the general formula A[B12−x ]O19−y ,with 0 ≤ x ≤ 1 and 0 ≤ y ≤ 2. The group is divided into subgroups, based on the dominant A cation: magnetoplumbite

subgroup (A = Pb), hawthorneite subgroup (A = Ba), and yimengite subgroup (A = K). Hibonite-(Fe) has been renamed
to chihuahuaite.
Walentaite group
The walentaite group has been established; it currently
includes four mineral species. Minerals of the walentaite group have the general formula [(A1,A10 ,A2,
3+)(H2 O)n][BxAs3−x
M1(M2)2 (T O4 )2 (O,OH)7 ]. The groupis divided into subgroups based on the dominant T cation:
walentaite subgroup (T = P), and halilsarpite subgroup (T =As).

IMA 19-I: redefinition of fairbankite

283
Renaming of shuiskite
After the approval of shuiskite-(Cr) (IMA no. 2019-117;
see above), and considering that the nomenclature of
the pumpellyite group is based on suffixes, it was decided to change the name of the mineral shuiskite toshuiskite-(Mg). The rationale in the nomenclature of thepumpellyite group is that the root name depends on thedominant – always trivalent – cation at M2, whereas thesuffix depends on the dominant cation at M1. Currently
the root names are as follows: pumpellyite (M2 = Al),julgoldite (M2 = Fe3+ ), shuiskite (M2 = Cr), okhotskite(M2 = Mn3+ ), and poppiite (M2 = V3+ ). The valid species
are as follows: pumpellyite-(Mg), pumpellyite-(Fe2+ ),pumpellyite-(Fe3+ ), pumpellyite-(Mn2+ ), pumpellyite(Al), julgoldite-(Fe2+ ), julgoldite-(Fe3+ ), julgoldite-(Mg),shuiskite-(Mg), shuiskite-(Cr), okhotskite, and poppiite. The
latter two minerals are (still) without suffix as they standalone with their root name.

Proposal 19-I is accepted, and fairbankite is redefined. The
previously accepted formula was Pb2+ Te4+ O3 . Now it has
been proven that sulfate group is an essential constituent and4+
the formula has been changed to Pb2+
12 (Te O3 )11 (SO4 ).
