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 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
New mineral proposals approved in April 2025

Nomenclature/classification proposals approved in May 2025
Nomenclature scheme for the aeschynite group
(Zeying Zhu, Can Rao, Hong Yu, Zhenyu Chen, Bin Wu, Rucheng Wang, and Denghong Wang)
A nomenclature scheme for the aeschynite group has been approved, and end-member formulae were established for some minerals. The aeschynite group comprises aeschynite-(Ce), redefined as Ce(TiNb)O6, aeschynite-(Nd), redefined as Nd(TiNb)O6, aeschynite-(Y), redefined as Y(TiNb)O6, rynersonite, CaTa2O6, tantalaeschynite-(Ce), Ce(TiTa)O6, tantalaeschynite-(Y), redefined as Y(TiTa)O6, and vigezzite, redefined as CaNb2O6.
Nioboaeschynite-(Ce) and nioboaeschynite-(Y) have been found to be equivalent to aeschynite-(Ce) and aeschynite-(Y), respectively. Therefore, both nioboaeschynite-(Ce) and nioboaeschynite-(Y) have been discredited.
Nomenclature scheme for the monazite supergroup
(Pavel Uher, Frédéric Hatert, Martin Ondrejka, Peter Bačík, Jiří Sejkora, Radek Škoda, and Martin Števko)
The monazite supergroup has been established. Phosphates (monazite-(Ce), monazite-(La), monazite-(Nd), monazite-(Sm), monazite-(Gd), and cheralite) and arsenates (gasparite-(Ce), gasparite-(La), and rooseveltite) belong to the monazite group, whilst silicates (huttonite) and chromates (crocoite) are individual members of the supergroup.
