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。借助于电子顺磁共振、成矿溶液电导度和红外光谱方法对刺猬沟金矿区石英进行了分析。结果表明,电子顺磁共振吸收峰强度、成矿溶液电导>0.2矿化好。与石英中Au含量呈正相关关系。成矿溶液电导度>35.7μS,DCO2度和红外光谱测定的DCO2上述研究获得的信息,对该区找矿和矿床评价具有指导意义。
Quartz is an important gangue, as well as a main gold-hosting mineral in the in Ciweigou deposit. The quartz is studied using an electron paramagnetic resonance (EPR), infrared spectrum (IR) and the electrical conductible degree of ore-bearing fluids. The results show that the absorption of EPR and electrical conductible degree and D_(CO_2) of IR of quartz has a positive relation to its Au content. That quartz's electrical conductible degree is over 35.7 μS, and D_(CO_2) is greater than 0.2 would indicate intense gold mineralization. This information of quartz is significant to the prospecting and evaluation of gold deposits in the area.
