NOMENCLATURE PROPOSALS APPROVED IN MAY 2015

IMA 15-F: Baumhauerite-2a
Proposal 15-F is accepted, and ‘‘baumhauerite-2a’’ is renamed ‘‘argentobaumhauerite’’.

IMA 15-G: Wernerbaurite and schindlerite
Proposal 15-G is accepted: wernerbaurite and schindlerite do not contain significant hydronium, but must be considered as ammoniumbearing decavanadate minerals. The simplified formula of wernerbaurite is {(NH4)2[Ca2(H2O)14](H2O)2}{V10O28}, and the simplified formula of schindlerite is {(NH4)4Na2(H2O)10}{V10O28}.
