Abstract: The Zhaoping gold belt is an important gold metallogenic belt in Jiaodong gold district in China.The gold belt has proven gold reserves more than 1 000 t along and near the fault zone with length of hundred kilometers in Zhaoping gold belt.The deep area under the coverage in the middle-south section of the gold belt is the core area for further prospecting.However，the mineralization information under the cover layer is difficult to obtain，so it is necessary to improve the efficiency of regional prospecting for the deep ore-bodies to achieve the prospecting breakthrough.The different-level ore-controlling factors in the gold belt are analyzed,the physical properties of the ore-controlling factors are conducted comparison analysis from the aspects of ore-controlling fault structure,ore-bearing altered granite and mineralized bodies.The comprehensive geophysical anomalies of the ore-controlling factors are clarified,the corresponding relationship between the ore-bodies,ore-controlling factors and geophysical anomalies are defined.The integration geophysical exploration model of the deep ore-bodies under coverage area in Zhaoping gold belt is established.Based on the above analysis results,a deep metallogenic target area is positioned and predicted,besides that,the drilling verification is also conducted.The study results show that the integrated geophysical prospecting model of the deep area of the altered rock type gold deposit is good for solving the deep prospecting problems under the coverage area of the gold belt,besides that,it also contribute to improving the deep prospecting efficiency under the coverage area of the gold belt.
