| Abstract: | Based on regional data of gravity survey at scale 1:200000 and air magnetic survey at scale 1:50000 characteristics of deep faults and magmatic rocks are summarized and the buried and semi-buried intrusive bodies and faults are delineated. Data of geology and mineral resources are combined with the geophysical-geochemical data to analyze relation between the intrusive body and the fault and show characteristics of the gravity and magnetic field in the potential areas in the metallogenic belts and areas. The results show 5 potential areas and provide important information for prospecting buried ore or blind ore bodies. |
