3 Nomenclature/classification proposals approved in April 2023
3.1 22-L: establishment of the palmierite supergroup
(Rafał Juroszek, Irina O. Galuskina, Biljana Krüger, and Hannes Krüger)
Proposal 22-L is accepted, and the palmierite supergroup is defined. This supergroup contains two groups of minerals: the palmierite group, including palmierite, K2Pb(SO4)2, and kalistrontite, K2Sr(SO4)2, and the tuite group, including tuite, Ca3(PO4)2; gurimite, Ba3(VO4)2; and mazorite, Ba3(PO4)2.
3.2 23-C: establishment of the minium group
(Jörgen Langhof, Henrik Friis, Dan Holtstam, Andreas Karlsson, and Muriel Erambert)
Proposal 23-C is accepted, and the minium group is defined. The group consists of five valid members: minimum, Pb4+Pb
O4; trippkeite, Cu2+AsO4; schafarzikite, Fe2+SbO4; igelströmite, Fe3+(SbPb)O4; and the newly approved species manganoschafarzikite, Mn2+Sb
O4 (IMA 2022-129; see CNMNC Newsletter 72). Existing mineral names are recommended to be used as root names in the future, and prefixes should be added to indicate substitutions at the octahedrally coordinated sites of the crystal structure.
3.3 23-D: redefinition of the formula for benyacarite
(Ian E. Grey and Ferdinando Bosi)
Proposal 23-D is accepted, and the ideal formula of benyacarite is revised as (H2O)2Mn2Ti2Fe3+(PO4)4(OF)(H2O)10 • 4H2O.
3.4 23-E: redefinition of avdeevite
(Adam Pieczka)
Proposal 23-E is accepted, and the ideal formula of avdeevite is revised as NaAl4(Be5Li)(Si6O18)2(H2O)1−2.
3.5 23-F: discreditation of minasgeraisite-(Y)
(Daniel Atencio)
Proposal 23-F is accepted, and minasgeraisite-(Y) is discredited as an ordered intermediate member between datolite and hingganite-(Y).
4 Nomenclature/classification proposals approved in May 2023
4.1 Changes in the cerite group nomenclature
(Daniel Atencio, Andrezza A. Azzi, Kai Qu, Ritsuro Miyawaki, Ferdinando Bosi, and Koichi Momma)
The cerite group belongs to the cerite supergroup, together with the merrillite group. Whereas the latter remains unchanged, some nomenclature/classification changes have been made to the cerite group. Minerals of the cerite group have the general formula A9XM[T7O24Ø4]Z3. The group is divided into the cerite subgroup (Z = OH) and the taipingite subgroup (Z = F). Cerite-(Ce) has been renamed cerite-(CeCa) ((Ce7Ca2)□Mg(SiO4)3(SiO3OH)4(OH)3), aluminocerite-(Ce) has been renamed aluminocerite-(CeCa) ((Ce6Ca3)□Al(SiO4)3(SiO3OH)4(OH)3), ferricerite-(La) has been renamed ferricerite-(LaCa) ((La6Ca3)□Fe3+(SiO4)3(SiO3OH)4(OH)3), and taipingite-(Ce) has been renamed taipingite-(CeCa) ((Ce7Ca2)□Mg(SiO4)3[SiO3(OH)]4F3). The newly approved mineral aluminotaipingite-(CeCa) ((Ce6Ca3)□Al(SiO4)3[SiO3(OH)]4F3) (see this newsletter) belongs to the taipingite subgroup, too.
