摘要
利用现代信息技术开展三维成矿预测,是开展深边部有色金属找矿勘查工作的迫切需要。设计有色金属三维成矿预测信息系统的目标、原则、体系结构、数据库和包括地质数据管理、三维地质建模、三维空间分析、三维成矿预测等功能模块,并对轮廓线三维插值建模法、证据权三维成矿预测法、逻辑回归成矿预测法这三种系统关键技术进行研究。系统设计集成了主流三维成矿预测技术方法,可满足多类型、多尺度的有色金属三维成矿预测需求,为后续系统开发及应用提供指南。
To apply modern information technology in three-dimensional mineralization prediction is the urgent need of non-ferrous metal prospecting exploration in deep and marginal areas.In this paper,the objectives,principles,architecture,database and the functional modules including geological data management,3D geological modeling,three-dimensional spatial analysis and three-dimensional mineralization prediction of non-ferrous metal three-dimensional metallogenic prediction information system are designed.And three key methods of contour three-dimensional interpolation modeling,three-dimensional mineralization prediction and logical regression metallogenic prediction are studied.The system integrates the mainstream three-dimensional metallogenic prediction technology to meet the multi-type and multi-scale non-ferrous metal three-dimensional mineralization prediction demand,which can provide guidance for the follow-up system development and application.
