https://doi.org/10.1180/mgm.2021.93NOMENCLATURE/CLASSIFICATION PROPOSALS APPROVED IN NOVEMBER 2021IMA 21-G: Hiärneite: crystal structure, chemical formula and classificationProposal 21-G is accepted, and based on SCXRD data the formula of hiärneite is revised from (Ca,Na,Mn2+)2(Zr,Mn3+)5(Sb,Ti,Fe3+)2O16 to Ca2Zr4Mn3+SbTiO16. Hiärneite belongs to the calzirtite group of minerals, which also includes calzirtite [Ca2Zr5Ti2O16] and the structurally related cubic mineral tazheranite [(Zr,Ti,Ca)(O, □)2].
IMA 21-H: Redefinition of bixbyite and definition of bixbyite-(Fe) and bixbyite-(Mn)
IMA 21-H: Redefinition of bixbyite and definition of bixbyite-(Fe) and bixbyite-(Mn)Proposal 21-H is accepted. The name ‘bixbyite’ becomes a series name for material with a bixbyite structure, space group Ia , and Fe3+ or Mn3+ as the dominant trivalent cation (it also includes the orthorhombic polytype of Mn2O3, with space group Pcab). Bixbyite-(Fe) is defined as the Fe3+ dominant part of the series, with an ideal formula (Fe,Mn)2O3, and bixbyite-(Mn) is defined as the Mn3+ dominant part of the series, with an ideal formula Mn2O3.
