NOMENCLATURE PROPOSALS APPROVED IN AUGUST 2018
 
IMA 18-D: Redefinition of the ideal formulae for mottanaite-(Ce) and ciprianiite The proposal 18-D is accepted. Accordingly, the ideal formula of mottanaite-(Ce) is changed from Ca4(Ce,Ca)2AlBe2[B4Si4O22]O2 to Ca4(Ce,REE)Σ2Al(Be1.5☐0.5)Σ2[B4Si4O22]O2, and the ideal formula of ciprianiite is changed from Ca4[(Th,U)REE]Σ2Al☐2[B4Si4O22](OH)2 to Ca4[(Th,U),Ca]Σ2Al(Be0.5☐1.5)Σ2[B4Si4O22](OH)2.
