摘　　要：义兴寨金矿床中黄铁矿矿物学特征研究表明:黄铁矿的晶形愈复杂含金性愈好;含金性好的黄铁矿S,Fe及S相对于Fe均有亏损,晶体中存在晶格缺陷,为Au元素的混入提供了有利空间;黄铁矿的晶胞参数a及红外吸收峰高I2/I1值与其含金量呈良好的正相关关系。该项研究对于寻找同类型的金矿床具有重要的指导意义。The research on the pyrite mineralogical characters of Yixingzhai ore deposit shows that the Au-bearing property is better for more complex pyrite crystal type. There are obvious pyrite sulfur, Fe and S/Fe ratio losses better Au-bearing pyrite, and the lattice defect in the kind of pyrite supplies the favorable space for the interfusion of Au. Furthermore, there are positive correlations among the crystal cell parameter a, infrared absorption peak ratio I2/I1 and the gold content. The result might be significant for guiding the exploring work of the same mineralization type gold ore deposit.
