摘　　要：矿产资源是人类赖以生存的物质基础,是人类社会进步的根本保障。近些年,随着浅部矿藏的减少,寻找深部隐伏矿体日益紧迫。文中通过对以往相关研究的梳理和总结,基于现代成矿理论、成矿预测理论和矿产资源勘查与评价理论,依托数据库技术、3S技术、三维可视化技术及现代数学理论与方法,综合地质、地球物理、地球化学、遥感等多元信息,探索了一套适用于区域隐伏矿体三维定量预测评价的方法和流程,提出了基于基础地质与矿产地质相结合的控矿因素定量表达方法,创新了不整合面、碳酸岩层等新变量的提取和以统计收敛性划分成矿有利区间等方法,成功将传统区域二维成矿预测方法与先进的三维可视化技术结合,使区域范围内矿产资源预测研究拓展到三维空间,更有利于区域范围内隐伏矿体的圈定工作,亦可为今后的三维预测工作提供参考。Mineral resources are the material basis of human survival and the fundamental guarantee of the progress of human society. In recent years, with the reduction of shallow deposits, looking for deep concealed ore bodies is increasingly urgent. By collating and summarizing the previous studies, and based on modern metallogenic theory, modern metallogenic prediction theory and mineral resources prospecting and evaluation theory, this paper explores a set of methods and processes suitable for three-dimensional quantitative prediction and evaluation of regional concealed ore bodies, which rely on database technology, 3S technology, 3D visualization technology and modern mathematical theory and methods, and integrating multi information as geology, geophysics, geochemistry, remote sensing, etc. This paper presented new methods of quantitative expression of ore-controlling factors by combining the basic geology and ore geology concept, new methods of extractions of new variables like unconformity and carbonate rock stratum, and new method of division of favorable mineralization interval according to statistical convergence. This work combines the traditional two- dimensional regional melallogenie prediction methods and advanced visualization technologies successfully, extends the prediction of mineral resources within the region to three-dimensional space, makes it more conducive to concealed ore delineation work within the region, and also provides a reference for future three dimensional prediction.
