www.mindat.org/min-833.htmlNamed by T. Nakai in 1938 according to composition and similarity with gadolinite, but considered questionable. Discredited in 2006 (considered Ca-bearing gadolinite under current site-dominance rules). A variety of Gadolinite-(Y) A Ca-dominant gadolinite. Although Ca dominates over any individual ...

www.mindat.org/min-1628.htmlCalciogadolinite-(Y) A Ca-dominant gadolinite. Although Ca dominates over any individual REE, the current site dominance rules do not allow for species status because trivalent elements (mostly REE) dominate over total divalent elements (mostly Ca) on the site.

www.minsocam.org/ammin/AM52/AM52_1523.pdfThe 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
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.
