摘要
简述了瞬变电磁法的基本原理及在黔西北猫猫厂铅锌矿区的工作方法及找矿效果。在Ⅰ矿段通过工作获得5个TEM异常,选择3个异常进行工程验证,均在深部见矿,说明这种方法在高阻围岩条件下,寻找深部隐伏金属矿体是十分有效的。此外,该方法还能较准确地确定断裂构造的位置,在第四系厚沉积物覆盖区,可为地质填图提供较好依据。
The basic principle of Transient Electromagnetic method is briefly described firstly, application and evaluation of this method on Maomaochang Pb-Zn ore prospecting district at northwest Guizhou province are then introduced. The results show that it is an effective method to explore concealed metal ore-bodies under the conditions of high-resistivity wallrocks. Furthermore, this method can also indicate the position of fracture structure, and can provide good evidences for geological mapping in the quaternary thick-sedimentary coverage area
