3 Nomenclature/classiﬁcation proposals approved
in July 2024

3.1 IMA 24-A: deﬁnition of the neotype material for
elbaite
(Ferdinando Bosi, Federico Pezzotta, Henrik Skobgy,
Alessandra Altieri, Paolo Ballirano, Riccardo Luppi, Ulf
Hålenius, Gioacchino Tempesta, Giovanna Agrosì, and Jiˇrí
Sejkora)
Proposal 24-A is accepted, and a neotype sample is deﬁned
for the mineral elbaite, ﬁrst described in 1913. The type lo-
cality is the Rosina pegmatite, located about 100 m south of
the village of San Piero in Campo, Elba island, Italy. Neo-
type material is deposited in the collections of the Museo
Universitario di Scienze della Terra (MUST), Dipartimento
di Scienze della Terra, Sapienza Università di Roma, Italy,
catalogue number 33383/406.

3.2 Nolanite supergroup
(Nikita V. Chukanov, Vasilisa M. Gridchina, Ramiza K.
Rastsvetaeva, Natalia V. Zubkova, and Igor V. Pekov)
The nolanite supergroup is established. In the frame of
this, the mineral rinmanite-(Zn) is renamed zincorinmanite-
(Zn). The supergroup is divided into the kamiokite group
(including the species iseite, kamiokite, and majindeite), the
nolanite group (including the species akdalaite, ferrihydrite,
and nolanite), and the rinmanite group (including the species
rinmanite and zincorinmanite-(Zn)), in accordance with the
largest charge of the species-deﬁning cations.

3.3 Kröhnkite supergroup
(Frank C. Hawthorne)
The kröhnkite supergroup is established. It is divided
into the brandtite group (including the species brandtite,
dobšináite, kröhnkite, roselite, rrufﬁte, wendwilsonite, and
zincroselite), the collinsite group (including the species
anorthoroselite, cassidyite, collinsite, gaitite, hillite, nick-
eltalmessite, parabrandtite, and talmessite), and the fairﬁeld-
ite group (including the species fairﬁeldite and messelite).
Dondoellite is an unassigned member of the supergroup un-
til an isotypic mineral has been approved, whereupon a new
group can be proposed.

4 Other issues

4.1 Loparite-(Ce) or loparite?
In the IMA List of Minerals the mineral loparite-(Ce) is
still mentioned as such, with the Levinson modiﬁer indicat-
ing the dominating REE. However, after the approval of the
report on the perovskite supergroup (Mineralogical Maga-
zine, 81, 411–461 (2017)), the mineral was renamed loparite,
since it was shown that REEs are not a dominant constituent
at any site. The end-member formula could be written as
(Na0.5REE0.5)TiO3, in which REEs are subordinate cations
at the A site and appear in the formula for charge balance
requirements only. Thanks are owed to Daniel Atencio for
noticing this inconsistency.

4.2 Correct chemical formula for launayite
In the IMA List of Minerals the chemical formula of lau-
nayite is given as CuPb10(Sb,As)13S20. This is a typo for
CuPb10(Sb,As)13S30. The latter formula is the correct one for
evident stoichiometric reasons and is also given in the IMA-
approved report on sulfosalts (European Journal of Mineral-
ogy, 20, 7–46 (2008)). Thanks go to Frank de Wit for spotting
this.
