【摘要】 地球化学元素的多元统计分析可以推测地化元素在复杂的成矿过程中的演化特征,为预测找矿提供有用的微观信息。选取马关都龙锡锌矿区曼家寨矿段13号主矿体有关元素进行聚类分析、因子分析研究。研究结果揭示了矿区内成矿作用的复杂和多次矿化叠加改造现象,说明Sn和Zn的富集是由于后期地质作用叠加改造的结果,指出了In和Cd可作为区内找Sn和Zn的近矿指示元素。更多还原

【Abstract】 The ore-forming process is characterized by complexity and diversity,and the difficulty lies in the understanding of evolutional characteristics of geochemical elements.The metallogenic process can be inferred and the useful microscopic information can be obtained for further exploration.In this paper,the cluster analysis and factor analysis of No.13 ore body in Mangjiazhai Sn-Zn polymetallic ore block of the Dulong ore district have revealed that the metallogenic process was very complex and superimposed by repeated mineralization.It is considered that the enrichment of Sn,Zn resulted from the superimposition of subsequent geological activities,and that In,Cd seem to be main indicator elements in search for Sn,Zn in the mine.更多还原
