江西相山火山盆地三维地质建模的实践与思考
摘要
Abstract
The 3D geological modeling is a data model based on the analysis of geological spatial structure for displaying, editing, counting and outputting by the computer technology.In the 1980s,China began to carry out 3D modeling work on important geo-logical sections such as sedimentary basins and deposits.In 2012,the CGS officially launched the pilot work of the 3D geological sur-vey, and combined 3D geological modeling with regional geological mapping. 3D geological model from Xiangshan volcanic basin was built in 5 different scales and different data sources in the GOCAD(Geological Object Computer Aid Design)software platform, and three modeling methods were explored,i.e.,digital geological mapping modeling,geological profile modeling and multi-source data fusion modeling.It integrated the surface of digital geological mapping in Xiangshan area with deep geophysical exploration and the analysis of drilling data.The digital geological mapping modeling has the great popularization value since it not only can be used as a new way of expression of surface regional geological mapping but also can be used as a transitional model for deeper level's 3D geological survey deployment foundation and the modeling constraints. 3D dimensional geological modeling emphasizes the organic integration of multi-source data and confirmation with each other,and the need of merging geological and geophysical exploration results,information technology,and multi-disciplinary integration. 3D modeling is an effective method for understanding geological features of the geological bodies,geometry of geological phenomena and paragenesis of formation in the 3D space.关键词
