1878 Brush & Dana in Amer. Jrnl. Sci. 116 35 In addition to the above minerals, as original constituents of the same deposit, are amblygonite (hebronite), and a phosphate of manganese isomorphous with scorodite which we shall describe under the name reddingite.
1964 Amer. Mineralogist 49 1122 Landesite, a rare hydrated manganous-ferric phosphate, is an alteration product of reddingite which, in turn, is derived from the hydration and alkali-leaching of lithiophilite-triphylite at the Berry Quarry, Poland, Maine.
