Nomenclature of the triphylite group of minerals

Abstract M M 4, where M M M = □ M = 2 + 2 + 3 + 3 + T 5 + 2 + 4)] and lithiophilite [LiMn2 + 4)] and their oxidation products heterosite [Fe3 + 4) ] and purpurite [Mn3 + 4)], as well as the Na-bearing phosphates natrophilite [NaMn2 + 4)] and karenwebberite [NaFe2 + 4)]. The Li–Mg-bearing phosphate simferite has been redefined as LiMg (PO4). Ferrisicklerite and sicklerite correspond to intermediate phases in the triphylite–heterosite and lithiophilite–purpurite solid solutions; consequently, according to the CNMNC dominant-constituent rule, they are discredited. A new mineral oxidation sequence is defined, which considers the different oxidation capacity of iron and manganese, and therefore replaces the traditional Quensel–Mason sequence. The formula calculation procedure for Li-bearing species, based on electron microprobe analyses and single-crystal X-ray diffraction data, is also described.
