Abstract
This paper has described the role of large-scale high-precision aeromagnetic survey in the prospecting for nonmagnetic ore deposits,made a comparative analysis of the results obtained in Shanting area of Shandong Province by several times of survey which used different scales under different surveying conditions,and summed up their magnetic anomaly characteristics.On such a basis,the authors hold that large-scale high-precision aeromagnetic survey can obtain abundant information.It is also thought that,as this method can recognize weakly magnetic geological bodies,it can be effectively used in other fields in addition to the prospecting for ferromagnetic ore deposits.
