摘要
要在-1 000 m以下深部矿体的定位取得突破,需结合该区的成矿地质背景,选择正确的勘探方法,然后对靶区进行验证。大尹格庄金矿床产于招平断裂带中的构造蚀变岩中,其上下盘岩性变化大,电阻率差别也大,因此,适合采用大地电磁法(EMT)对深部矿体进行空间定位。其断裂及裂隙构造十分发育为选择构造地球化学原生晕法圈定矿体对应的平面范围提供了条件。实践证明,该方法为适合本区深部找矿的简单有效方法。
In order to make sure the location of the orebodies 1 000 meters below the ground,it is essential to consider the geological background of the mining area,select the suitable exploration method and verify the target area.Dayingezhuang gold deposit occurs in the altered rock of Zhaoping fault belt and its huge variation of the lithology in the upper and lower plate causes the large resistivity differences.So it is suitable to use magnetotelluric method（EMT） on the spatial orientation of the deep orebodies.And its well-developed fault and fracture structures make the selection of the tectonic geochemical primary halo meanings effective.In fact,the two meanings are the suitable methods for the deep exploration in the area.
