NOMENCLATURE/CLASSIFICATION PROPOSALS APPROVED IN APRIL 2023

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.

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⁺Pb²⁺₂O₄, trippkeite, Cu²⁺As³⁺₂O₄, schafarzikite, Fe²⁺Sb³⁺₂O₄, igelströmite, Fe³⁺(SbPb)O₄, and the newly approved species manganoschafarzikite, Mn²⁺Sb³⁺₂O₄ 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.

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.

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.

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).

NOMENCLATURE/CLASSIFICATION PROPOSALS APPROVED IN MAY 2023

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 A ₉XM[T ₇O ₂₄Ø₄]Z ₃. 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], 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) also belongs to the taipingite subgroup.
