非传统矿产资源定量预测的理论思考

Theoretical Consideration to Quantitative Forecasting of Nontraditional Mineral Resources

近年来 ,国内外对新型非传统矿产资源研究都予以高度重视 ,解决矿产资源短缺的途径之一就是非传统勘查理论与方法研究 .“相似类比”一直是地质研究所遵循的基本原理 ,但对于具有“点型分布”的矿床 ,以及对于研究区不存在已知矿床没有现成模式进行“相似类比” ,什么样的理论可以用来指导我们的找矿预测呢 ?多样性是复杂系统中客观事物外在表现的基本特征 ,成矿专属性只是成矿多样性的一种特例或表现形式之一 .因此 ,非传统矿产资源预测评价的新理论必须在理论基础上既适用于寻找传统矿床类型 ,又不忽视对新类型矿产资源的发现、预测和评价 .对于区域成矿预测的分析研究 ,成矿地质信息的数字化、定量化是地质异常识别与提取的重要基础 ,矿化特征的数字化、定量化是成矿多样性分析与评价的关键步骤 ,区域成矿规律的数字化。

Recently, research of nontraditional mineral resources has been received more and more concern. It is one way that researching of nontraditional theories is to support mineral demands. In geology, we have followed the principle of similitude analogy to analyze the geological processes for a long time, which based on that present is the key to the past. But, it is not applicable to forecasting new type of deposit in some areas, nor does some special ore forming events. The diversity is essential characteristics of a complex system; metallogenetic specialization is one of unusual representation of metallogenetic diversity. Therefore, nontraditional theory of forecasting has to be applicable both discovery of traditional deposits and finding new type of mineral resources. The quantitative research is an intersection of the geoscience and a systematic mode of description through symbols and highly structured rules, which it is for exploring essential earth system. For metallogenetic forecasting, digital and quantitative analysis of geological information is to recognize the ore forming geological anomalies, digital and quantitative analysis of mineralization characters is to distill the metallogenetic diversity, and digital and quantitative analysis of district metallogenetic rules is to analyze the spectrum of deposits.
