荒漠戈壁覆盖区的矿产勘查技术探讨

摘要

荒漠戈壁覆盖层具有组成复杂、厚度较大且分布不均一等特征，不利于采用常规方法找矿，而穿透深度较大的物探和化探方法，如大极距激电法、金属活动态提取法、地电化学法、遥感异常提取法和新发展起来的非线性理论等，将会在未来的荒漠戈壁覆盖区找矿工作中发挥越来越大的作用。%The gobi-overburden is complexing ,thick and uniform distribution in thickness ,which have bad effect on con-ventional prospecting methods ,but the deep-penetrating geophysics and geochemistry methods will play an important role in it,such as long-space induced polarization ,MOMEO and geoelectrochemical method ,besides that ,remote sensing ano-moly extraction method and developing nonlinear theory also have good prospecting .
