NOMENCLATURE PROPOSALS APPROVED IN NOVEMBER 2015
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.
IMA 15-I: Bafertisite Proposal 15-I is accepted, and the chemical formula of bafertisite is revised as follows: Ba2Fe2+4Ti2(Si2O7)2O2(OH)2F2, with Z = 4. Fe2+ is the dominant cation of the O sheet, OH and F are ordered at the XO A and XP M sites and must be presented as two groups of anions in the mineral formula: (OH)2 and F2. The structural data for bafertisite (holotype material) are: triclinic; space group C1; a=10.665(2), b=13.743(2), c=11.721(3) Å, a=90.30(4), ß=112.27(2), ?=90.00(3)°, V = 1589.8(8) Å3.
REVISED CHEMICAL FORMULA
A paper on the mineral benleonardite has been published recently [Mineralogical Magazine, 79, 1213–1221 (2015)] in which the ideal chemical formula of the mineral is given as Ag15Cu(Sb,As)2S7Te4. In this formula, based on new EPMA and SCXRD data, Cu is present as an essential component, whereas it was lacking in the previously accepted formula of benleonardite. These data were examined carefully by the CNMNC officers and were considered reliable. Accordingly it was agreed to modify the formula of benleonardite in the official IMA List of Minerals.
ERRATUM
IMA No. 2015-035 Oxo-mangani-leakeite In CNMNC Newsletter 26, the mineral namewas typed incorrectly as oxo-mangani-leakite. The correct name is oxo-mangani-leakeite.
