摘要
对招平断裂带上的大尹格庄、夏甸、山后、大磨曲家等金矿进行了矿体原生晕测量,分析了Au、Ag、Cu、Pb、Zn、As、Sb、Bi、Mo、Hg等10种元素,统计了微量元素含量和相关系数。与金相关的元素中,As在每个矿床均出现;Ag、Pb、Cu、Sb在大部分矿床出现;Mo、Bi、Zn只在个别矿床出现。前缘晕元素As是最好的成矿指示元素,可以用As的含量结合其他元素异常开展地球化学深部预测。划分了As、Au元素强弱异常标准,As元素含量大于4×10-6为强异常,1.5×10-6～4×10-6为中等异常,小于1.5×10-6为弱异常;金元素含量大于35×10-9为强异常,10×10-9～35×10-9为中等异常,小于10×10-9为弱异常。总结了深部地球化学预测的3种准则,经矿区实际验证预测效果较好。
Primary halo inverstigation has been carried out in Dayingezhuang,Xiadian,Shanhou,Damoqujia gold deposits which hosted in Zhaoyuan-Pingdu fault zone.Au,Ag,Cu,Pb,Zn,As,Sb,Bi,Mo and Hg elements were analyzed.Trace elements contents and their pertinence coefficients were Statisticed.All four gold deposits appeared As,most gold deposits appeared Ag,Pb,Cu,Sb,individual gold deposits appeared Mo,Bi,Zn,foreside halo As was the best indication element,we can put up exploration forecast with contents of As and other elements geochemistry abnormity.Abnormity standards of As,Au elements were compartmentalized,more than 4×10-6 of As contents were strong abnormity,1.5×10-6～4×10-6 was middling abnormity,less than 1.5×10-6 was weak abnormity;More than 35× 10-9 of Au contents were strong abnormity,10×10-9～35×10-9 were middling abnormity,less than 10×10-9 was weak abnormity.Three rules of geochemistry forecast for deposits depth were summarized,these rules had preferably forecast effect through validating.
