摘　　要：西藏尼木地区斑岩铜矿是近年发现的大型斑岩型铜矿。在矿产勘查过程中采用综合物探方法进行圈定勘查目标、缩小找矿靶区、确定异常源、推测矿化空间等项工作,取得了较好的勘查效果,说明在西藏尼木县斑岩铜矿区综合运用地面高精度磁测、激电中梯、激电测深等物探勘查方法,能减少物探的多解性,较好地解决具体的地质问题。Nimu porphyry copper deposit is a large-sized one discovered in recent years. During the ore prospecting the integrated geophysical methods is used to locate prospecting goals and anomly sources thus to reduce the size of the target. The integrated geophysical methods proved effective. Integration of high precision magnetic survey,IP gradient survey,IP sounding etc. can overcome any ambiguites of the geophysical interprectation and properly solve the geological problems.
