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

锆石中钛的微探针分析：二次荧光的估计

采用微探针研究了高钛玻璃（TiO ₂ ≈ 16 wt%）的二次荧光对相邻无钛锆石表观钛含量的影响。事实证明，小晶体（<10 µm）不适合分析。在大锆石晶体（20-30 µm）的边缘，Ti 估计的误差可能达到 10-23%。然而，在大晶体（>30 µm）的核心中，微探针分析给出了几乎不失真的钛含量。
