摘　　要：为研究广东阳春地区的区域地球化学特征,划分地球化学分区,根据阳春地区1∶5万水系沉积物测量样品的分析数据,统计了元素地球化学背景、含量平均值、浓集比率、变化系数、成矿指数等多个参数,分析了Sn、Cu、Pb、Zn等12个元素在各地质子区及在空间上的分布特征,丰富了本区的地球化学基础资料,对找矿工作有一定参考意义。In order to study the regional geochemical characteristics and to divide the geochemical zones in Yangchun area in Guangdong,the geochemical element background,the average content,the concentration ratio and variation coefficient,mineralization index and so on are calculated according to the analysis data of1∶50 000 sedimentary samples in Yangchun area.The distribution of 12 elements such as Sn,Cu,Pb and Zn in the subareas and the spatial distribution characteristics are summarized.The geochemical basic data are enriched for this area.There is a considered significance for the exploration work in the region.
