Abstract: The study on the thermoluminescent feature of quartz in Wenyu gold deposit shows that obvious differences of thermoluminescent feature exist between gold-bearing quartz and barren quartz. The thermoluminescent curves of gold-bearing quartz possess weak single peak, the peak intensity is lower than 150cps and the total thermoluminescent intensity is lower than 10000cps. However,the thermoluminescent curves of barren quartz possess middle to high single peak, the peak intensity is usually bigger than 150cps, and the total intensity bigger than 10000cos. these indicators have great directing significance on exploration and e-valuating the gold-bearing feature of mineralized veins in this district.
