The moderate to strong positive correlation between Ba and [P.sub.2][O.sub.5] (r = 0.83) and between Ba and REEs (r > 0.7) may provide reason for the presence of the Al-bearing secondary phosphates like gorceixite [Ba[Al.sub.3][(LREE, P[O.sub.4]).sub.2][(OH).sub.5].[H.sub.2]O] (Costa and Araujo, 1996) that was not detected by XRD analysis.
