高精度磁测在区域矿产调查中的应用——以1∶5万平里店、道头幅为例

Application of High Precision Magnetic Survey in Regional Mineral Survey——Taking Pinglidian and Daotou Map Sheet with the Scale of 1 ∶50000 as an Example

根据山东省胶西北地区2幅1∶5万地面高精度磁测资料,对工作区内岩性界线、断裂构造进行了划分,取得了良好的效果,为研究以金为主的矿产成矿规律和圈定成矿预测区提供了地球物理信息。同时指出了高精度磁测在区域地质填图、断裂构造研究及区域成矿预测等方面的作用。

According to two map sheets of ground high precision magnetic survey data with the scale of 1 ∶50000 in northwest Jiaodong area in Shandong province,lithologic boundaries and faults have been divided in the work area and achieved good results. Geophysical information has been provided for studying metallogenic rules and delineating metallogenic prediction areas. The role of high precision magnetic survey in the regional geological mapping,faults research and regional metallogenic prediction have been pointed out as well.
