    www.minsocam.org/ammin/AM52/AM52_1523.pdf The ferric calciogadolinite occurred as aggregates of light brown, trans-parent crystals. The gallium calciogadolinite also occurred as small, transparent but colorless crvstals. Precise determinations of the refractive indices of these phases could not be made because of their small particle size. Their mean indices of
  • List of minerals (synonyms) - Wikipedia

    en.wikipedia.org/wiki/List_of_minerals_(synonyms) The International Mineralogical Association (IMA) is the international group that recognises new minerals and new mineral names, however minerals discovered before 1959 did not go through the official naming procedure, although some minerals published previously have been either confirmed or discredited since that date.. This list contains mineral synonyms, varieties and polytypes.
