NOMENCLATURE/CLASSIFICATION PROPOSALS APPROVED IN SEPTEMBER 2020

IMA 20-D: Wöhlerite group

Proposal 20-D is accepted and the wöhlerite group is established. It currently includes 9 mineral species: cuspidine, baghdadite, burpalite, låvenite, normandite, niocalite, janhaugite, wöhlerite, and hiortdahlite. The chemical formula of the latter mineral has been revised to Na₂Ca₄(Ca_0.5Zr_0.5)Zr(Si₂O₇)₂OF₃. Marianoite has been discredited as it is identical to wöhlerite.

Cerite supergroup

The cerite supergroup has been established and includes the cerite group (5 members) and merrillite group (8 members). Cerite-(La) has been renamed ferricerite-(La) since Fe is dominant in the M site. It has the formula (La,Ce,Ca)₉Fe³⁺(SiO₄)₃(SiO₃OH)₄(OH)₃.
