摘要 评价和区分大型矿床 ,一直是近年矿产勘查活动的焦点。最新研究表明 ,大型、巨型矿床与一般矿床的主要并可以量化的区别 ,在于大型、巨型矿床有着巨量的成矿元素供应与聚集。这种巨量的成矿元素供应 ,不是传统意义上元素的全量 ,而是能被成矿过程所利用的活动态分量。文中提出了基于元素立体分散模式和成矿可利用金属分量评价和区分矿床规模的一种定量地球化学模型和方法。 Mineral exploration activity is being focused on large or giant ore deposits. The main and quantitative difference between large ore deposits and small ones lies in the tremendous endowment and accumulation of elements for the formation of large ore deposits. The available contents of metals play the most important role in the formation of ore deposits. This paper describes a geochemical quantitative assessment model and approach for large ore deposits based on 3 dimension geochemical dispersion patterns and available metals for mineralization.
