| 摘 要： | 使用近红外光谱仪对五龙沟金矿区主要蚀变矿物进行了光谱测试，获得该矿区主要蚀变矿物的光谱数据；同时选择部分具有代表性的样品进行详细的镜下鉴定，并将镜下鉴定结果与野外实测光谱曲线进行对比分析，检查其对五龙沟金矿体矿化蚀变快速检测的有效性和准确度。对比分析结果表明，蚀变分带与矿体吻合较好，对矿化分带具有较好的指示意义，也为该区的金矿勘探提供了依据。

| Abstract: | Near-Infrared Spectrometer was used to investigate main alteration minerals in Wulonggou gold deposit and got their spectroscopic data. The typical samples were chosen for detailed microscopic identification, and the result was compared with the filed spectrometer curve. The efficiency and accuracy of gold deposit alternation fast investigation was checked. The analysis showed alteration zonation was well in accord with ore body, had a better guidance for mineralization, and supplied dependence for gold deposit exploration. |
