摘　　要：青海门源钼矿属于构造控矿类型,钼矿赋存于花岗岩次级构造破碎带内,为寻找深部隐伏矿体,在矿区开展大地电磁法(EH4)进行找矿,通过电阻率分布情况及岩矿石物性特征,推断隐伏矿体的平面位置、深度、规模等信息。Menyuan Mo deposit in Qinghai belongs to the type of structure ore control. Mo deposit is in the secondary structure fracture zone of granite. In order to find the deep buried orebody, the prospecting with magne- totelluric EH4 has been carried out in the orefieht. The site, depth, scalof buried orebody have been inferred ac- cording to the electric resistance distribution and characters of rock and ore.
