摘要
为探测地下复杂地质构造情况,经过实地踏勘以及方法可行性试验后,可采用可控源音频大地电磁测深法。利用可控源音频大地电磁法为勘察手段,在对野外资料进行圆滑滤波以及静态校正后,以卡尼亚电阻率二维反演剖面为实际勘察资料,在作出电阻率二维反演剖面的基础上,作出了地质推断解释剖面。结合工区地质平面图资料以及物性参数,对地下复杂地质结构进行了推断解释。在重点勘探1000m深度范围内划分了断裂构造,圈定了岩体,划分了地质界面,取得了明显的效果,为深入找矿提供了依据和方向。
In order to detect the complex geological conditions of the underground,the on-the-spot survey is made and the test research on the feasibility of the method is done.It is found that the controlled source audio frequency magnetotelluric sounding method can be adopted.In this paper,the controlled source audio frequency magnetotelluric sounding is applied to deducing the interpretation of the complex underground geological structure with the help of geological plane data and physical parameters.For the purpose of mainly focusing on exploring the area of 1000 meter depth,the fault structure is divided,the rock mass is circled and the geological interface is also divided.A good result is obviously obtained.
