Abstract

With analyzing defects of traditional geological information expression method and the significance of carrying out three-dimensional geological mapping，through comprehensive research of data for drill holes，terrain and prospecting line profile，the three-dimensional visualization geological model of Changgou gold deposit is established on the basis of Surpac software platform for the first time，which shows the spatial distribution regulation of terrain，tectonics and ore-bodies intuitively.The results of comprehensive geological research and 3D model analysis show that Changgou gold deposit is strictly controlled by near EW-NWW striking shear zone DSZ3 developed in Silurian regional deformation metamorphic rocks and the lateral secondary fault fracture zones.The distribution of gold veins in the mine area is mainly along the S2 foliation.The prospecting direction in western segment of the deposit should be in the deeper places of its southwestern part，along with the NW trending ore （mineralized）） zone of NWW 285o ~310o.The establishment of 3D visualization geological model of Changgou gold deposit on the basis of Surpac software provides a significant indication for ore prospecting in the further exploration.

Key words： Changgou gold mine; Surpac software; three-dimensional model; location prediction; south Qinling Mountain
