摘要
通过开展1∶1万高精度磁测和可控源音频大地电磁法(CSAMT)的综合物探方法对测区Pb、Zn综合异常进行查证。通过对实测物探资料进行处理分析与解释推断,并结合地质测量及1∶1万土壤地球化学测量成果,推断出三处可能存在铅锌多金属矿化的异常体,基本查明了区内磁异常特征和电性特征,两者相互验证,相互补充,取得了较好的找矿效果,证明了该方法在多金属矿勘查中的可行性和有效性。
This paper verified the comprehensive geophysical prospecting methods for meas- uring comprehensive anomalies in Pb and Zn survey area through the conduct of 1 ： 10 thousand high precision magnetic survey and controlled source audio-frequency magnetotel- luric method （CSAMT）. Based on the process and interpretation of geophysical data, and combined with the geological survey and 1 ＂ 10 thousand soil geochemical survey results, three abnormal bodies existing lead-zinc polymetallic mineralization are inferred in this are- a, and the magnetic anomaly characteristics and electrical characteristics are mainly found out, which verify and complement each other. It has obtained the good results of prospec- ting mine, and proved the feasibility and effectiveness of this method introspecting poly- metallic ore.
