Description
| - Ferrotapiolit jako pseudomorfóza po stibiotantalitu z lepidolitového pegmatitu v Laštovičkách, příklad hydrotermální alterace v stabilním Ta/(Ta+Nb), při alteraci nedochází ke změně Ta a Nb (cs)
- Dark brown porous ferrotapiolite is a dominant alteration product in pseudomorphs after primary stibiotantalite from the lepidolite pegmatite at Laštovičky, western Moravia, Czech Republic. Two compositionally distinct varieties of ferrotapiolite were recognized a volumetrically dominant Fe3+-rich phase and a very rare Sb-rich phase. Niobium-rich ferrotapiolite, with up to 17.51 wt.% Nb2O5 (0.61 apfu), is highly heterogeneous with Ta/(Ta+Nb) of 0.69 to 0.84 and Mn/(Mn+Fe) of 0.01 to 0.05; Fe2O3calc. 3.09 wt.% (0.18 Fe3+ apfu; ~ 0.16 to 0.22 Fe3+ apfu from Mössbauer spectroscopy) in the ferrian, and Sb2O3 9.87 wt.% (0.34 Sb3+ apfu) in antimonoan variety. The unit-cell dimensions of ferrian ferrotapiolite a = 4.746-4.757 Å and c = 9.198-9.244 Å calculated from X-ray powder diffraction data indicate highly variable degrees of structural order. The substitution NbTa-1 is dominant; the minor substitution Fe3+3Fe2+-2R5+-1 typical of the ferrian ferrotapiolite strongly suggests incorporation of Fe3+ into the
