摘　　要：对湖南水口山矿区硅化角砾岩体中的石英进行了热释光分析。石英的热释光特征与成矿作用密切相关,热释光特征能较好反映出成矿信息。石英的热释光强度(峰值)与成矿强度呈正相关关系,天然热释光峰值大,成矿强度也大。天然热释光具有310℃–330℃的发光峰反映成矿强烈,人造热释光具有200℃–220℃的发光峰则反映金成矿作用强。热释光分析可作为重要的找矿指标之一。Thermoluminescence characters of quartz from silicified breccia, which is related to mineralization, in Shuikoushan deposit, Hunan provinces, were analyzed. The TL characters of quartz are closely related to mineralization and can reflect the ore-forming information. The TL intensity （peak value） of quartz has direct correlation to the ore-forming intensity, that is, when the NTL peak value is larger the ore-forming intensity is also larger. The NTL emission peaks at 310℃-330℃ reflect the intensive Au mineralization, and the ATL emission peaks at 200℃-220℃ reflect the Au mineralization. Thermoluminescence analyses may suggest the prospecting index.
