Synonym:
A synonym of Niobobaotite
The Nb analogue of baotite. Unique combination of (dominant) elements.
As rare granules, up to 0.5 mm in diameter, in sulfide- and siderite-rich carbonatite. The grains are blotchy and form irregular patches. Optically sharply defined.
Electron microprobe data (wt.%):
BaO 35.73
TiO2 14.28
FeO 6.76
CaO 0.03,
Nb2O5 26.98
SiO2 13.40
