综合物探方法在刚果(金)马本德地区铜矿的应用研究

文章在研究刚果马本德地区矿床地质特征的基础上,在已知矿体上进行四种装置的激电法(中梯、偶极-偶极、联合剖面和对称四极测深装置)和高密度电阻率方法应用,通过已知矿体与物探异常的对照研究,总结了该区域含矿岩石和主要围岩的电性异常规律,集成了适用于已知矿床的物探技术方法组合。将该方法组合推广到周边矿区应用,且对物探异常进行钻孔验证,在高阻中高幅频率异常区分别见到了三处厚度不等的矿体,取得了较好的应用效果。

Application of comprehensive geophysical method in copper deposits in Mabende area of D.R.Congo

After a study to the geological characteristics of the deposits in Mabende of D.R.Congo,this paper applied induced polarization method with four different devices (intermediate gradient device,dipole-dipole device,composite profiling device and symmetrical four-pole sounding device)as well as high density resistivity method in the known orebodies.By comparing the known orebodies and geophysical anomalies,the authors summarized electric anomaly regularity of ore-bearing rocks and main wall rocks in this area,and designed a combination of geophysical methods which was suitable for prospecting works of known deposits.Then the authors applied this methods combination in peripheral mining area,and verified the geophysical anomalies by conducting borehole drilling.Three orebodies with different thickness were observed in the high-resistivity high-intermediate frequency anomaly area.The methods combination achieved good results.
