sanidine

The results show that the TL signals of pumice and sanidine phenocryst have better thermal-stability, so they can be used for TL dating.

结果表明，浮岩和透长石的TL信号具有良好的热稳定性，适用于TL测年。

The results indicate that the colourless and transparent one is sanidine with homogeneous exsolution microstructure and the reddish one is orthoclase or sanidine without exsolution microstructure.

结果表明，两者成分差别不大，而结构差别较大，无色透明的为透长石，出溶叶片发育；微红色的为正长石或低透长石，出溶结构不发育。
