... ), which is not consistent with dynamic recrystallization. The high concentrations of Y-REE-Nb in titanite-(I) and their highly heterogeneous distributions may contribute to the early breakdown of titanite besides fluid availability. Niobium, in particular, is more compatible in rutile than titanite...

... contained as substituent in other carbonates. Niobium is with [71 x] the most enriched element in all tailings, while the enrichment of other HFSE is minor (Th [22 x], U [9.4 x], Ta [4.8 x]). The enrichment of Th and U can be explained, partly, by the presence of Th- and U-bearing carbonates and monazite...

..., requiring specific processes to fractionate ( Green 1995 ). Nonetheless, niobium-tantalum-oxide minerals (NTO) commonly record considerable degrees of Nb/Ta fractionation in pegmatitic systems (e.g., Černý and Ercit 1985 ; Beurlen et al. 2008 ; Wise et al. 2012 ; Fuchsloch et al. 2019 ).
