摘　　要：对铜山铜矿岩石及矿体的微量元素地球化学特征用多元统计分析方法进行了初步研究，查明了成矿元素在各类岩石中的分布特征及铜、金矿化的指示元素，并采用浓集指数法计算了矿体的垂向分带序列，建立了区分不同矿化类型及接触带矿体深度变化的元素比值标志。为找矿勘探及深部评价提供了良好的标志。n this paper、the microelement geochemistry of rocks and orebodies in Tongshan Cu ore deposit is characterized by multi-variable statistical analysis.The distribution of metallogenic elements in each type of rocks and the indicator elements for Cu andAu mineralization have been found out.In terms of concentration index,the vertically zoning sequence of orebodies is calculated. Element ratio indexes,by which mineralization types and the orebody depths at contact zone can be distinguished,are set up,which can be used to prospect and evaluate ores in deep Earth′s crust.
