Abstract: On the basis of the information of geology and geophysics,by studying on the characteristics of strata and rock mass,a 3D hidden geological model in shallow-covered areas is constructed taking Yun-cao area in Anhui Province as an example.It introduces how to divide the modeling units and how to con-struct geological-geophysical model and 3D geological model,and a parallel model of strata and intrusions and a thinking of “first in separation and then in combination”are pointed out to build the final 3D hidden geological model considering the developmental conditions of intrusion and shallow intrusive rocks in this area.It is found that the resulting-model can reveal the distributions of physical properties of hidden geo-logical bodies,major faults,folded structures and magma bulge structure.In addition,it can display grav-ity and magnetic regional field,fault distribution,known ore occurrence,diorites and Zhouchongcun For-mation to identify the spatial positions of metallogenetic favorable sections by 3D visualization.
