摘　　要：拉陵灶火铜多金属矿床位于伯喀里克-香日德印支期Au-Pb-Zn-Mo-石墨-萤石(Cu、稀有、稀土)成矿带西段,属矽卡岩型矿床,由于地表被第四系覆盖,地表地质工作难以发挥作用。这里通过在该区开展的高精度磁法测量、激电中梯测量、连续电导率测量等多种地球物理工作方法解决了第四系厚覆盖区找矿困难问题。研究发现,中-强磁异常边部的低阻中高极化激电异常是本区重要的物探找矿标志。Lalingzaohuo copper polymetallic deposit is located in the west section of Au-Pb-Zn-Mo-graphite-fluorite(Cu,rare and rare earth)metallogenic belt in the indosinian period of Behleg-Xiangride,and is a skarn type deposit.Because its surface is covered by quaternary system,surface geological work is difficult to play a role.In this paper,the difficulties of prospecting in the quaternary thick overburden area are solved by means of high-precision magnetic survey,induced polarization intermediate ladder survey and continuous conductivity measurement in this area.
