摘要
覆盖区寻找隐伏矿成为当前找矿工作的热点问题,为了能在地表地质信息少的黄土覆盖区,寻找隐伏的有经济价值的矿床,本文以沙坡岭钼矿为例,综合应用r能谱、高精度磁法、高密度电法三种地球物理方法进行找矿勘探,辅以偏提取化探法对地球物理异常进行约束,结合地质资料进行解译,预测了有利的成矿区域,通过钻探得到了有效验证,初步建立了黄土覆盖区钼矿的综合地球物理找矿模式,为下一步的综合勘探打下了基础.
Searching for the concealed deposits is a focused issue of the current prospecting in covered areas.In order to find out valuable concealed deposits in loess-covered areas with little geological information of the surface,taking the Shapoling Molybdenum Mine as an example,this paper presents how to use comprehensive geophysical prospecting methods including Gamma-ray survey,magnetic survey and high density resistivity method to conduct prospecting.The geophysical interpretation is made according to the partial extraction geochemical survey and the geological information.Then the promising mineralizing region is predicted and identified by the drilling.The comprehensive geophysical prospecting model of molybdenum mine with loess-covered is preliminarily set up,and the foundation is established for the following comprehensive exploration.
