摘要
Geological information obtained from field investigations and surveys is discrete data. Traditional methods can only display this information in planes or profiles or a static three-dimensional way. The three-dimensional geological modeling is intuitive, three-dimensional and dynamic, and makes expression of geological results understandable. The three-dimensional geological modeling is a new tendency for various geological prospecting. Henan Province Institute of Geological Survey has studied 3D geological modeling at the experimental site of the Yushan bauxite deposit in Henan Prov- ince. This paper presents the workflow and comparison of 3D geological modeling using three sets of software of CTECH MVS 8.2 of USA, Mieromine 2010 of Australia and MAPGIS_G3dProjeet of China in an effort to provide insight for the next work.
