Abstract:
The spectral characteristics of Fe-Niobite, Fe-Niobotantalite, Tapiolite,Ge- rmannobite and Ixiolite in Pegmatite were studied by the tachnique of laser microspectral analysis. The contents of 5 minerals were determined quantita- tively. The equilibrium coefficients of elements were determined. ,The precision and accuracy were good.。
