矿产资源勘查与评价学科发展动态──记第五届国际矿产资源学术讨论会

DEVELOPMENTS OF MINERAL RESOURCES EXPLORATION AND EVALUATION: INTRODUCTION TO THE FIFTH INTERNATIONAL SCIENTIFIC CONFERENCE ON MINERAL RESOURCES

随着计算机价格的不断降低和性能的不断改进，形成了一些资源远景分析、矿产资源定量评价以及相应的风险评价的新方法。以美国、澳大利亚、日本、中国、加拿大和巴西等国家的研究成果为代表，主要表现在地质模型与风险分析、矿产资源勘查评价的三钱可视化与GIS的结合以及勘查决策的技术方法等方面。三维地质模型、GIS、遥感和可视化研究将会进一步深入发展，使得大量提取的地质信息有效应用于矿产—资源—经济联合评价中。

In recent years major improvements in the cost and functionality of desktop computer-based sys-tem have provided some mechanisms to identify mineral prospect, quantitative analysis of mineral re-sources,and assess the risk associated wlth thcse evaluations. The main developments consist of geological model with risk analysis, combmation of 3D visualization of mineral resources exploration and evaluation with GlS and new technology of exploration,which are summarized from research results of U. S., Aus-tralia,Japan,China,Canada, Brazil and so on- ln the future,ge0logical modeling with 3D,GIS,remote sens-ing and visualization are deeply developed,which help quantitatively extract geological information from large amounts of diverse data to use in the assessment process of mineral,resources and economics.
