    www.mindat.org/min-3777.html A variety of Pyrochlore Supergroup Černý et al. (1979) defined stibiobetafite as the Sb 3+ analogue of betafite; however, the type sample has Nb + Ta > Ti apfu, and Ca is the dominant species of the dominant-valence group at the A site. The type sample is now to be classified as oxycalciopyrochlore. It is not possible to calculate the formula of stibiobetafite studied by Tindle & Breaks ...
