摘要
主要介绍了双频激电法在辽宁某金矿勘查过程中的应用。对矿区190个标本进行了物性参数测量,并布置了4条对称四极测深剖面。通过双频激电中梯扫面测量,在矿区圈定3处激电异常,其中E1异常特征为高阻高极化异常,E2、E3异常特征为低阻高极化局部异常。结合地质资料和钻孔资料分析,证实异常与金矿化有关,并在矿区厘定出13条矿化异常带,为本区找矿及下一步的勘查提供决策依据。
In this study, authors mainly introduce the process of use of dual-frequency induced polarization in the rapid exploration of a gold mine, in Liaoning Province. The rock physical characteristics of 190 samples'were cal- ibrated and 4 symmetrical four-pole sounding profiles were laid out in the mining area. And three induced polari- zation anomalies were discovered by dual-frequency induced polarization intermediate gradient survey. E1 abnor- mal zone features high impedance high ehargeability anomalies, while E2 and E3 abnormalities were characterized with low resistance high polarization. In addition, synthesizing the geological and drill data analysis, it had been confirmed that the anomalies zone were mainly associated with the gold mineralization zone. The 13 mineralized a- nomaly zones were determined. It has proved the dual frequency induced polarization method fully adapt to the rapid exploration and provide a basis decision for further prospecting and exploration.
