摘　　要：石英是刺猬沟金矿重要的脉石矿物,也是金的主要载体。借助于成矿溶液电导度和红外光谱方法对刺猬沟与石英中金含量呈正相关关系,成矿溶液金矿石英进行了分析,结果表明,成矿溶液电导度和红外光谱测定的DCO2大于0.2矿化好。这对该找矿和矿床评价具有指导意义。电导度大于35.7μS。Quartz is an important gangue mineral and a main carrier of gold in the Chiweigou deposit. By means of electrical conductivity and infrared spectra of quartz, it is known that the electrical conductivity and the D(CO_2) of IR are in positive correlation with the Au content of quartz. Where electrical conductivity is higher than 35.7 μS and D(CO_2) higher than 0.2, gold mineralization is relatively good. Through the study, the authors have obtained some useful prospecting information, which is of guiding significance in the prospecting and evaluating of gold deposits in this area.
