摘要
通过对未蚀变岩石、近矿蚀变围岩及矿区内产出的黄铁矿中微量元素的分析对比，指出本区最佳指示元素是Ａｕ、Ｃｕ、Ｂｉ、Ｐｂ、Ｍｏ、Ａｓ；矿区产出的黄铁矿都富含Ａｓ、Ｓｂ、Ｂｉ，但富金黄铁矿中还富含Ｃｕ、Ｚｎ、Ｐｂ；成矿温度影响着含金黄铁矿中微量元素含量，成矿温度高的矿床中黄铁矿之Ａｓ、Ｓｂ、Ｈｇ、Ｚｎ含量低。
On the basis of comparison of trace elements in unaltered rocks,altered country rocks close to ores and pyrites occured in the mining area,it is indicated that the best indicating elements are Au,Cu,Bi,Pb,Mo,As in the area.Pyrites are all rich in As,Sb,Bi,but those rich in gold are also rich in Cu,Zn,Pb.The content of trace elements in the gold bearing pyrites is influenced by mineralization temperature,Pyrites with high mineralization temperature in the deposit are lower in As,Sb,Hg,Zn,but richer in gold.
