摘要
文章通过赣南6722铀矿床实例,运用Q型模糊聚类分析与蛛网作图相结合的对比方法,对6722铀矿床的成矿物质来源进行了研究,判明了含矿隐爆角砾岩、蚀变花岗岩与黑云母花岗岩具有密切的成因关系。笔者认为,采用多元数理统计分析与蛛网图相结合的研究方法可获得较多精细的、为蛛网图所隐匿的、但具有重要地质意义的地球化学信息,从而得到更为严谨、客观、并具有科学再现性的结论。
By means of Q-type fuzzy cluster analysis and spidergram on trace elements and REE data, the source of metallogenetic material for No. 6722 uranium deposit in South Jiangxi province is discussed in this paper. It has been discrminated that the ore-bearing cryptoexplosive breccia and the alted granite have a close genetical relationship with the biotite granite but not with the two-mica granite. It is concluded that mathematical statical analysis is able to obtain finer geochemical information with significant geological implications which are hidden in the spidergram. Thus more strict and objective conclusions with scientific reappearance may be drawn after using this method.
