详细

Microprobe study of the effects of secondary fluorescence from high-titania glass (TiO2 ≈ 16 wt %) on apparent titanium content in Ti-free zircon was conducted. It was demonstrated that small crystals (<10 µm) are not suitable for analysis. In boundary parts of large zircon crystals (20–30 µm) the error in Ti estimation may reach 10–23%. However, in central parts of large crystals (> 30 µm) the microprobe analysis gives practically undistorted titanium contents.
