摘要
成矿的复杂性,多样性是矿产资源的共性,其研究难点是成矿过程中的演化问题。地化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,从而为预测找矿提供有用的微观信息。选取广西大厂矿田钻孔有关元素进行了聚类分析、因子分析研究,揭示了矿区内成矿作用的复杂和多次矿化叠加改造的现象,Zn和Sn的富集与多金属硫化物密切相关,而与Au等元素表现出无直接关系。Sb、Pb、Ag和Cu可作为Zn和Sn的找矿指示元素。
The complexity and diversity of ore forming are common to mineral resources, the difficulty in whose research is the evolution of the ore forming process. The multivariate statistical analysis of geochemical elements can be used to deduce their evolution characteristics in complex ore forming process so as to provide valuable micro information for ore prospecting. Cluster analysis of the relevant elements of drill holes in Guangxi Dachang ore field was made. The factor analysis revealed the complex and superposed mineralizations in the ore formation in this ore field. The enrichment of Zn and Sn is closely related to multi-metal elements and has no direct relation with elements such as Au. Sb, Pb, Ag and Cu can be used as the indicating elements for ore prospecting.
