IMA 15-E: Spelling of names of eight mineral species Proposal 15-E is accepted, and the spelling of eight mineral names is modified as follows: achavalite becomes achávalite; behierite becomes béhierite; camerolaite becomes camérolaite; fabriesite becomes fabrièsite; remondite-(Ce) becomes rémondite-(Ce); remondite-(La) becomes rémondite-(La); sénarmontite becomes senarmontite; sérandite becomes serandite.
