..., metaswitzerite, rimkorolgite and switzerite. Overall, the structure is most similar to that of metaswitzerite. Long inactive manganese deposits, also rich in arsenic, in the Alpine tectono-metamorphic terrains of north-western Italy have yielded a variety of interesting secondary hydrothermal minerals...

... metaswitzerite. This proposal has been accepted by the New Mineral Names Commission, IMA. Averages of six microprobe analyses of metaswitzerite gave MnO, 46.05; FeO, 3.60; P 2 O 5 , 32.94 (all weight percent), with trace amounts of Si, Ca, Mg, and Al. The empirical formula of switzerite is (Mn 0.93 Fe 0.07 ) 3...

... graftonite-(Mn). In these masses the graftonite-(Mn) is often altered to secondary phosphate minerals and shows a rim of primary ferrowyllieite crystals. Electron microprobe analysis and X-ray powder diffraction were used to identify the following secondary phosphate minerals: vivianite, metaswitzerite...
