摘　　要：黄铁矿是硫化物矿床中的常见矿物,其形态、结构、物理性质及化学成分等均具有成因意义,黄铁矿的成分标型特征,特别是微量元素及其特征指数不仅能提供矿床类型、成因和成矿条件等重要信息,而且也是寻找硫化物矿床的重要找矿标志。通过对不同类型硫化物矿床中黄铁矿的Co,Ni,As,Au,Ag,Se,Te,以及Co/Ni,Se/Te等特征值的研究,揭示硫化物矿床的成因意义。Pyrite is widely distributed in sulfide deposits.Morphology,crystal structure,physical property and chemical composition etc.of pyrite are of genetic significance.Especially,trace elements and their characteristic index can not only provide information of type,genesis,and ore-forming condition of the host deposits but also the prospecting mark of sulfide deposits.Study on characteristic value of Co,Ni,As,Au,Ag,Se,Te and Co/Ni,Se/Te ratio show that they are of genetic significance of the host ore deposits.
