摘　　要：综合物探方法一般指利用多种物探手段获取至少两种不同类型地球物理观测参数,利用参数互补减少异常多解性影响,以尽可能准确的获得有效找矿信息,以巴基斯坦某斑岩型铜矿区为例,利用小比例尺航磁和大比例尺地面高精度磁法以及瞬变电磁测深等物探手段,成功提取了成矿构造及隐伏火成岩分布,在此基础上,结合地质及钻孔资料总结了该区域地球物理找矿模式,为研究巴基斯坦俾路支省chagai地区斑岩型铜矿的找矿及矿床成因研究提供了参考。Comprehensive geophysical methods generally refer to the use of multiple geophysical methods to obtain at least two different types of geophysical observation parameters,using parameter complementarity to reduce the influence of anomalous multiplicity,in order to obtain effective prospecting information as accurately as possible.Taking a certain porphyry copper deposit area in Pakistan as an example,using small-scale aeromagnetic and large-scale high-precision ground magnetic methods,as well as transient electromagnetic sounding and other geophysical methods,the ore-forming structures and the distribution of hidden igneous rocks were successfully extracted.Based on this,combined with geological and drilling data,the geophysical prospecting model in the region was summarized,providing a reference for the exploration and genesis research of porphyry copper deposits in the Chagai area of Balochistan Province,Pakistan.
