在某硫化镍矿区用充电法获得了异常,从中扣去点电源场,并对综合异常进行分解,求得各个导体顶板的位置.工程验证结果找到了预期的矿体,说明所用工作方法是有效的.现在作为一个实例,予以介绍.矿区是一倒转单斜构造.分布的地层有三迭系紫红色砂砾岩(T_3y),其上为浅变质岩带(P_2),由浅色硅质岩、云母石英片岩(局部还有绿色泥岩)所组成,是本区的含矿层.岩浆岩主要是燕山期超基性岩
Abnormalities were obtained by charge method in a nickel sulfide mining area, the point power field was deducted from it, and the comprehensive anomaly was decomposed to obtain the position of each conductor ceiling. The project verification result found the expected orebody, indicating that the working method used was valid Now, as an example, it is introduced that the mining area is a reverse monoclinic structure with three layers of fuchsia sandy conglomerate (T_3y) distributed over it, and a shallow metamorphic belt (P_2) composed of light-colored chert, mica Quartz schist (with green mudstone locally), and is the ore-bearing layer in this area.The magmatic rocks are mainly Yanshanian ultrabasic rocks
