通过对矿区实施1∶5000土壤地球化学测量,确定该区的指示元素为Au、Cu、Pb、Zn、As,选用传统的统计方法确定各元素的异常下限值分别为6×10~(-9)、30×10~(-6)、40×10~(-6)、150×10~(-6)、50×10~(-6),据此发现了一批有价值的地球化学异常区。对各元素地球化学异常区的找矿潜力进行分析,结合地层、岩性、构造等有利控矿因素综合评判主成矿元素异常、元素组合异常,圈定出3个找矿靶区。在Ⅰ号异常靶区内,Au与As、Cu、Pb在空间上具有良好的叠合性,经工程布置发现了M1~M7含金石英脉矿体,圈定了Ⅰ号、Ⅱ号矿体;在矿区西部Ⅲ号异常靶区,Au与As、Zn异常叠合良好,经工程验证,在此发现M11、M12、M13等多...

Through the implementation of 1∶5 000 soil geochemical survey, the authors determined the indicator elements of Au, Cu, Pb, As and Zn. By choosing the traditional statistical method, the authors calculated the threshold of each element in the soil, i.e., Au is 6×10~(-9), Cu is 30×10~(-6), Pb is 40×10~(-6), Zn is 150×10~(-6), and As is 50×10~(-6). On such a basis, a group of valuable geochemical anomaly areas were detected. The prospecting potential of the geochemical anomaly area were analyzed in detail. In combination with favorable ore-...
