IMA 16-A Gadolinite supergroup

Proposal 16-A on the gadolinite supergroup is accepted. The supergroup is divided in two groups, defined on the basis of the tetrahedral cations: Si⁴⁺ in the gadolinite group, and P⁵⁺ or As⁵⁺ in the herderite group. The gadolinite group is further divided in two subgroups: the gadolinite and datolite subgroups. The herderite group is also divided in two subgroups: the herderite and drugmanite subgroups. Bakerite is discredited.

Seidozerite supergroup

The seidozerite supergroup has been established. The supergroup is divided into four groups: rinkite group, bafertisite group, lamprophyllite group, murmanite group, and includes 45 mineral species. As it was recognized from the revised end-member formulae that some minerals of the supergroup have species-forming rare-earth elements, the name rinkite has been changed to rinkite-(Ce), mosandrite to mosandrite-(Ce), and hainite to hainite-(Y).

Hyalotekite group

The hyalotekite group has been established. It includes the minerals hyalotekite, khvorovite, kapitsaite-(Y) and itsiite.
