摘　　要：本文研究了吉林省南部的通化、白山地区主要煤矿的煤炭中微量元素含量及组成特征 ,结果表明 ,煤炭中多数微量元素低于克拉克值 ,呈富集状态。相关矩阵及聚类分析表明 ,煤炭中微量元素与基质元素之间、微量元素之间有着密切的依存性。由于本地区基岩———玄武岩中微量元素背景较高 ,而且煤的变质程度较高 ,故大多数微量元素的含量高于东北地区的平均含量。This paper studied the contents and constituent of major and trace elements in coal in main mines of TongHua.Baishan Region of Ji Lin Province.The result indicated that the content of many trace elements in coal are lower than their Clarke values, being in enrichement state.Correlation matrix and cluster analysis showed that the trace and major elements、trace and trace elements in coal are closely related.The trace elements is higher background value in the basic rock-basalt of this regions,the types of coal are more metamorphic,the content of trace elements are higher than the average content in Northeast of China.
