THE 3D MODELING METHOD BASED ON PROFILES AND ITS APPLICATION IN BENXI, LIAONING PROVINCE

With the GOCAD software, the 3D modeling method based on profiles (3DMMBOP) is put forward for metallogenic belt modeling. In order to reveal the deep geological situation and concealed iron ores in Benxi area, the 3D geological modeling method is established based on profiles in a total area of 907 km². The obtained 3D subsurface geological structures show developed broad and gentle folds, intense faulting and buried basement up to 4200 m deep. The areas with shallow metamorphic basement have a great potential for iron resources exploration. The practices prove that 3DMMBOP is an effective method for metallogenic belt three-dimensional modeling.
