土壤地球化学测量在云南保山鸡飞金异常查证中的应用与找矿效果

The application of soil geochemistry survey to anomalies varify in the Jifei gold anomaly area of western Yunnan Province and its effect

通过对鸡飞金异常区实施1∶10000土壤地球化学测量,确定该区的指示元素为Au、As、Sb、Hg,通过地球化学统计分析,发现了多个有价值的金异常。对各金异常区进行找矿潜力分析,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2个找矿有利地段。

Through the implementation of 1∶10000 soil geochemical survey in the Jifei gold anomaly area,the authors determined the indicator elements of Au,As,Sb and Hg.Through the geochemical statistical analysis,On such a basis,many valuable gold anomaly areas were detected.The prospecting potential of the gold anomaly area were analyzed in detail.In combination with favorable ore-controlling factors such as strata,lithology and structure,the authors synthetically evaluated main ore-forming elements and the abnormal element combi-nation,and then selected two prospecting target areas.
