矿床模型综合地质信息预测技术研究

随着中国国民经济持续快速发展,中国对矿产资源的需求呈现了快速增长的趋势,资源短缺已经成为制约中国经济又好又快发展的主要瓶颈之一。为了解决矿产资源短缺问题,对陆地近地表未查明矿产资源潜力的区位、数量和质量的评价工作已经成为当前十分迫切的任务。文章对矿床模型综合地质信息预测技术体系进行了详细、系统的介绍。该体系以地球动力学、成矿动力学和成矿系列理论为指导,深入开展区域地质构造研究,最大限度地分析地质构造的成矿信息,以各级成矿区带为单元,划分主要矿产的矿床预测类型,建立矿床模型,总结区域成矿系列。全面利用物探、化探、遥感等资料所显示的地质找矿信息,运用体现地质成矿规律内涵的预测技术,全面、全过程应用空间数据库及GIS技术,在圈定成矿预测区的基础上估计潜在资源量。

Methodology of deposit modeling and mineral resource potential assessment using integrated geological information

With sustained and rapid development of the national economy,China's demand for mineral resources is rapidly increasing.This has resulted in resource shortage,which has strongly restricted Chinese economic development.In order to resolve the shortage of mineral resources,it has become an impending task for us to find out the location,quality and quantity of near-surface undiscovered mineral resources.This paper introduces a systematic methodology of ore deposit modeling and mineral resource potential assessment,using integrated geological information.This methodology is based on geodynamics,metallogeny and metallogenic series.It emphasizes the in-depth study of regional geological structures,and the gathering of metallogenic information from geological structures.Taking different levels of metallogenic belts as units,we carry out the classification of mineral deposit types for main mineral products,which facilitates the building of deposit models and the summarization of regional metallogenic series.Besides using information obtained by geophysical,geochemical and remote sensing data and the prediction technique based on geological metallogenic laws,we further apply spatial database and GIS techniques throughout the whole process to delineate a metallogenic prognosis tract,and to estimate the quantity of the potential resource.
