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 asechynite-(Ce) and aeschynite-(Y), respectively. Therefore, both nioboaeschynite-(Ce) and nioboaeschynite-(Y) have been discredited.

3.2 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.

Uwe Kolitsch:
Da ist beim Copy-pasten ein Fehler passiert.
Die Minerale sind vom Newsletter 84, während der Abschnitt "3 Nomenclature/classification proposals approved in May 2025" vom neuen Newsletter 85 ist.

Stefan:
Danke für die Korrektur, ist ausgetauscht.
