吉林闹枝金矿床石英热发光特性研究

THERMOLUMINESCENCE OF QUARTZ IN THE NAOZHI GOLD DEPOSIT,JILIN

热发光是石英的标型特征之一，在金矿找矿勘探中具有重要意义。石英中主要的发光中心为Ｏ－Ａｌ３＋－Ｍ＋（这里Ｍ是Ｌｉ，Ｎａ，Ｋ等），测试条件不同，石英的热发光光谱特征不同。在相同测试条件下，含金石英与不含金石英的热发光光谱特征也不相同。因此，石英的热发光是金矿找矿的一个重要标志。

The thermoluminescence is one of the typomorphic features of quartz, which has important meaning for theprospecting of gold deposits. The luminous center is mainly O-A13-M+ (here the M represents Li, Na, K etc. ) in the quartzcrystal. The thermoluminescence spectroscopies have different characteristics under different conditions,and the gold-bearingquartz and the gold-free one have different thermoluminescence spectroscopies under the same conditions. The results indicate thatthe thermoluminescence is an important criterion for the prospecting of gold deposits.
