异常结构三维综合系统的开发和应用

地球化学异常结构三维综合系统的开发和应用是为了满足地球化学多维异常体系的研究而逐步展开的。应用于深部找矿预测的多维异常结构方法,从钻孔岩芯直接采样,获得了具有真三维属性的地球化学数据,研究者迫切需要在三维场景下对所获三维地球化学数据进行解读和表达。异常结构三维综合系统(3D-MDAS)是利用三维可视化和地质体三维建模技术,在MapGIS K9平台上进行二次开发获得的。本系统实现了地上、地下数据模型的一体化显示,实现了实体模型与属性模型的耦合一体化显示,在此基础上还可以对异常结构进行空间分析,建立三维地球化学找矿模型。笔者详细阐述了三维异常结构3D综合系统的三维建模思路和技术,并用安徽马头矿区的实际应用成果给以说明。

THE DEVELOPMENT AND APPLICATION OF ANOMALY STRUCTURE THREE-DIMENSIONAL SYSTEM

With the geochemical multidimensional anomaly system, the development and application of geochemical anomaly structure＆#39;s 3D visualization have been carried out. Geochemical anomaly structure applied to the deep ore body prediction collects samples from drill core to get geochemical 3D data. So researchers urgently want to explain and map them. The geochemical anomaly structure system has been developed on the platform of MapGIS K9 using 3D visualization and 3D geological model technology. It has not only realized the integrating of data models on the ground and underground but also the integrating of solid models and attribute models. Analyzing geochemical anomaly structures and exploring ore models could be done in this system. The thought and technology for 3D anomaly structure and its application in the Matou mining area of Anhui Province have been elaborated in this paper.
