| 摘 要： | 以矿产系统勘查为目的,提出了"多目标矿产预测评价"新理念,根据矿产勘查不同阶段、不同比例尺的任务要求,划分出成矿区(带)、矿区(带)、矿田、矿床和矿体5类多目标矿产预测评价。前三者统称为区域多目标矿产预测评价。以滇西北地区喜马拉雅期富碱斑岩相关矿产预测评价为例,在"三联式"成矿预测理论指导下,较系统地开展了区域多目标矿产预测评价的理论探索与方法实践。研究认为,在区域多目标矿产预测评价中的关键问题是致矿地质异常解析、成矿多样性及其与地质多样性的关联分析、成矿谱系建立以及多目标矿产(矿床)定量预测评价模型研究。

| Abstract: | In order to explore for mineral deposits systematically,the authors put forward a new concept of multi-objective mineral prediction and assessment.Based on assignments and requirements of mineral exploration in different stages and at different scales,the authors classified the multi-target mineral prediction and assessment into five categories,namely:multi-objective mineral prediction and assessment on mineralization areas,ore-forming belts,ore fields,ore deposits and ore bodies.The first three kinds are jointly named as regional multi-target mineral prediction and assessment.As an example,the authors use the mineral deposits related to Himalayan alkali-rich porphyry systems in northwestern Yunnan Province.Using the theory of "three-component" resource prediction,the authors systematically developed the theories of regional multi-objective mineral prediction and assessment,and practiced the methods.The key problems in multi-objective mineral prediction and assessment are(1)analysis of geo-anomaly caused by minerals,(2)correlative analysis of diversity of mineralization and geologic diversity,(3)the establishment of a spectrum of mineral systems,and(4)research on the model of quantitative multi-objective mineral prediction and assessment. |
