聚类分析在534铀钼矿床研究中的应用

摘要

Cluster analysis,including Q-mode clustering and R-mode clustering,is a kind of statistical method in which similarity degree of some common properties of different geologic bodies and geologic phenomena are classified.On the basis of clustering for No.534 U-Mo deposit,the ore samples are divided into three groups,each with much different geochemical features.The uranium mineralization in deep of the eastern ore block of the deposit has the characteristics of ore root; while that in shallow has the characteristics of ore body.On the contrary,the mineralization in deep of western ore block has features of ore top.It is thus concluded that the deep part of the western ore block is promising for further exploration.%聚类分析是对不同地质体或地质现象的某些共同属性的相似程度进行分类的一种统计分析方法,分为Q和R两种.通过对534铀钼矿床聚类分析,将矿区样品分为3组,这3组样品具有十分不同的地球化学特征:东段深部的矿化蚀变具有矿根相特征,东段浅部具有矿身相特征,而西段深部具有矿顶相特征.可以进一步推断,西段深部具有较好的找矿前景.
