Niobium-tantalum oxide minerals in the Jezuitské Lesy granitic pegmatite, Bratislava Massif, Slovakia: Ta to Nb and Fe to Mn evolutionary trends in a narrow Be,Cs-richand Li,B-poor dike

Original language description

A complex assemblage of Nb-Ta-(Sn) oxide minerals occur in a relatively narrow (similar to 1-2 m thick) extensively albitized, Hercynian granitic pegmatite dike intruding biotite granodiorites near Bratislava, SW Slovakia. The dike shows enrichment in beryl (locally Cs-rich) but absence of Li- and B-rich phases. Compositions and textural relationships indicate complex evolutions of Nb-Ta oxide phases with several generations presenting distinct textural and compositional features. The first generation of the Nb-Ta minerals from the quartz-microcline-muscovite zone show Ta, Fe-rich compositions with Ta# [Ta/(Ta + Nb)]= 0.52-0.70 (Ct I columbite-tantalite), 0.88-0.90 (Tap I ferrotapiolite) and 0.73-0.86 (Fw I ferrowodgin-ite); Mn# [Mn/(Mn + Fe)]= 0.32-0.49 (Ct I), 0.06-0.10 (Tap I) and 0.33-0.41 (Fw I).
