摘　　要：介绍了石英热释光测量方法在石湖石英脉型金矿找矿试验中的应用,结合峰型(单峰、双峰)、峰点温度和发光强度,本区石英脉的热释光曲线可分为4种类型,其中两峰发光强度相当,且强度值较小的双峰型曲线对应含金性较好的石英。石英热释光的发光强度、峰点温度和金品位等值线图表明,发光强度较低的石英脉含金性较好,峰点温度的低值—中值区为有利矿段,石英脉含金性较好。Application of thermoluminescence measurement of quartz in Shihu gold deposit in prospecting is introduced in this paper. Considering peak type （single-peak, double-peak） , peak point temperature and luminescence intensity, thermoluminescence curves of quartz are classified into 4 types. Double-peak type curves that have equivalent luminescence intensity and relatively low intensity correspond to quartz veins bearing better gold potentiality. Some isograms about gold grade and-luminescence intensity, peak point temperature of quartz thermoluminescence indicate that quartz veins which have lower luminescence intensity and little-middle peak point temperature correspond to better gold potentiality.
