摘要
地质填图时,根据地表出露的岩性等进行勾连填图,对出露岩体或地层在深部的延伸等无法进行判断,进而影响地质背景的研判。地面高精度磁测成果能客观真实的反映不同构造单元及各种地质体的边界,对地质填图工作有巨大的指导意义。
During geological mapping,it is impossible to judge the extension of exposed rock mass or stratum in the deep part according to the lithology exposed on the surface,thus affecting the study and judgment of geological background.The results of high-precision magnetic survey on the ground can objectively and truly reflect the boundaries of different structural units and various geological bodies,which is of great significance for geological mapping.
