摘要
通过对主要微量元素数据的多元统计分析,探讨了该地区金矿的成矿物质来源。结果表明,成矿物质主要来源于洋壳向陆壳俯冲时产生的增生楔,地幔主要提供热源,并有少量物质参与;有效区分了不同类型的矿石和围岩,并分辨出了具过渡性质的蚀变围岩;对稀土元素的分析表明,除氧化矿石外,其它矿石的成矿物质来源应该是一致的。
Based on the multivariate correlation statistics analysis of trace element data,the ore-forming materials origin was researched.The results show that the ore-forming materials are derived from the accretionary wedge which created by dive from oceanic crust to continental crust,and the mantle offer the thermal resource.The different types of ores and country rocks and the transitional altered rocks are disting guished.It indicates obviously that the ore-forming materials of the ore are unanimous except the oxidative ores by the REE analysis.
