Abstract: Work area is located in Cao mill on the west side of the outer contact zone of granite in the body,the layer of the Archaean dantazi group,mainly for a syncline,a north east direction.The metallogenic hydrothermal activity,tectonic belt,fracture development in this area,ore controlling role.Geophysical prospecting work primarily in the IP intermediate gradient scanning and Wenner sounding,wherein the IP intermediate gradient scanning delineated the tectonic location,Wenner sounding accurate determination of mineralized body space forms.The combination of the two methods in the area to identify the distribution regularity of ore controlling structure,purpose,to achieve the best geological exploration results.
