The Petrogenesis of the East Tasmania Terrane Devonian Granites. Appendix 5.2 CL images of quartz mounts

The cathodoluminesence (CL) imaging of quartz mineral isolates in epoxy mounts from 12 Tasmanian Devonian granites are presented. These images were used to choose spots for analysis of O isotopes by ion microprobe and element concentrations by electron microprobe. The spots of the ion microprobe are arrowed and the electron microprobe spots were close to these spots. CL dark and light areas were selected in each magmatic grain studied.

本文展示了采自12件塔斯曼尼亚泥盆纪花岗岩的环氧树脂镶样靶片中石英矿物分离物的阴极发光（cathodoluminescence, CL）成像结果。
上述成像被用于选取分析点位，以通过离子探针开展氧同位素分析、通过电子探针开展元素浓度测定。
离子探针的分析点位已以箭头标注，电子探针的分析点位则紧邻上述点位。
本研究中每一颗被分析的岩浆颗粒均选取了阴极发光暗区与亮区。
