| 摘 要： | 随着信息技术的发展 ,矿产勘查已步入数字化、定量化研究的新阶段。“三联式”成矿预测以地质异常分析为基础 ,以成矿多样性分析与矿床谱系研究为指导 ,将地质异常、成矿多样性及矿床谱系 3方面定量化研究紧密结合形成矿产预测及定量评价的切入点 ,是实现“数字找矿”的创新探索。文中对“三联式”成矿预测的基本理论进行了论述 ,结合在固体矿产和油气资源预测评价中的最新研究成果 ,重点论述了“三联式”成矿预测中的地质异常动态演化解析思路和“5P”靶区逐步逼近法。研究认为 :不同时期地质异常各自包含的矿产类型、组合特征与资源潜力等均有明显差异 ,应用地质异常动态演化的解析思路与方法 ,有效提取与相应成矿事件密切相关的致矿地质异常 ,是提高预测成果科学预见性的关键。并且 ,随着“三联式”成矿预测研究的不断深入 ,找矿信息由少到多 ,找矿范围由大到小 ,靶区级别由低到高 ,找矿成功概率逐步增大 ,勘探风险逐步降低。“5P”靶区圈定 ,从 1P到 5P依次研究目标内涵增大、外延减小、预测对象 (矿产种类及成因类型 )渐趋明确。

| Abstract: | Stimulated by the exceeding progress of information technology, the development of mineral exploration has entered a new period of digitization and quantification. The "Three Components" approach of mineral prediction is suggested as a new approach to the "digital mineral prospecting", which is based on the geo anomaly analysis, directed by the research on the diversity of mineralization and on the spectrum of mineral deposits. Close combination of these three aspects of quantitative study makes a new starting point to the digital prospecting. In this paper, the basic theories of the "Three Components" approach of mineral prediction have been discussed. In addition, based on the new achievements in the studies on the prediction and assessment of solid minerals and gas oil resources, we have centered our discussion on the thought of analysis of geo anomaly evolution and on the "5P" method for approaching the target area in the "Three Components" approach of mineral prediction. |
