区域地球化学定量预测方法技术在矿产资源潜力评价中的应用

摘要

为科学评估我国重要矿产资源的潜力,本文首先客观地分析了当前矿产资源预测领域的现状,回顾并评述了三种地球化学定量预测方法(丰度法、面金属量法和地球化学块体法).其次通过整理、吸纳前人研究成果,在GIS技术平台上集成了以基础地质、成岩成矿机制、理论地球化学和勘查地球化学为一体的研究思路,概要论述了在III级成矿带中开展地质、地球化学找矿模型建立、地球化学定量预测区优选和资源量估算的方法技术.最后总结了地球化学定量预测的几点认识和探索了进一步发展的方向.%In order to scientific appraise the potential of important mineral resources in China, firstly, this paper objectively analyses the current situation of mineral resources prediction; moreover, three geochemical quantitative forecasting methods are reviewed and commented, whose names are abundance method, areal productivity method, and geochemical block method. Secondly, through summarizing and absorbing previous achievements, and integrating four disciplines composed by fundamental geology, mechanism of diagenesis and metallogenesis, theoretic geochemistry and exploration geochemistry, we generalized the establishment of geological-geochemical prospecting model, targeting method of geochemical potential prospecting area and mineral resources calculation on GIS platform. Finally, with reference to geochemical quantitative prediction, some conclusions are summarized and further development orientations are explored.
