摘要
在云南省麻栗坡县六位厂铅锌多金属矿区,选用大功率激电(IP)和电磁法(EH-4)进行物探勘查,前者大功率激电(IP)采用中间梯度装置,供电极距为1000m^1200m,供电电流2200~3200毫安,该物探勘查手段圈定了良好的找矿异常;后者电磁法(EH-4)其工作点距40m,电极距20m,工作频率10~100KHz分成高、中、低三个频率段,叠加次数8次以上,从而推测了深部地质构造特征,为该区地质找矿提供了良好的地质依据。
The high-power induced polarization （IP ） and electromagnetic method （E ） H-4 plied to Liuweichang Pb-Zn multimetallic orefield in Malipo,Yunnan. The former, high-power induced polariza-tion metliod, with the intermediate gradient set u p,power supply electrode spacing 1000m ？ 1200m,electrrent 2200？ 3200mA,the good prospecting anomaly has been outlined by this method. The latter, electromagneticmethod （E ） H-4, working point separation 40m,electrode spacing 20m, working frequency 10 ~ 100KHz,di-vided into high, middle, low 3 frequency band, superimposition time more than 8,inferred the deep geologicalstructural characteristics, which provides the good geological foundation for prospecting in this area.
