摘要
选择Au、Ag、Cu、Pb、Zn、Mo、W、Bi、Sb、As、Hg共 11项元素为指示元素,在栗子沟矿区开展 1∶1万土壤地球化学测量,运用迭代剔除法计算出矿区内元素地球化学特征参数,圈定单元素地球化学异常和综合异常,为进一步找矿提供了地球化学信息.采用规模指标法对综合异常评序,选择有望异常进行了工程验证,在含矿构造带的深部发现金矿体.与邻近矿区土壤地球化学特征进行对比,分析了矿区找矿前景.
Abstract
A total of 11 elements,including Au,Ag,Cu,Pb,Zn,Mo,W,Bi,Sb,As and Hg,were selected as indicator elements.A 1∶10 000 soil geochemical survey was carried out in Lizigou mining area.The iterative elimination method was used to calculate the element geochemical characteristic parameters in the mining area,delineate the single element geochemical anomalies and comprehensive anomalies,and provide geochemical information for further prospecting.The scale index method was used to evaluate the comprehensive anomaly sequence,and the expected anomaly was selected for engineering verification.A gold ore body was found in the deep part of the ore bearing structural belt.The prospecting prospect of the mining area is analyzed by comparing with the geochemical characteristics of the soil in the adjacent mining area.
