摘要苏丹东部的格达里夫盆地被认为是一个以大陆沉积和第三纪玄武岩熔岩流为主的大型构造凹陷。主要含水层是Gedaref砂岩含水层系统和玄武岩。对格达里夫盆地70口井的主要阳离子、主要阴离子、总溶解固体、碱度和硬度进行了采样和分析。这些数据用简单的统计处理，用Piper三线图表示，并作为聚类分析的对象。对所用方法的解释相互印证，将地下水分为两类。砂岩含水层的水主要以NaHCO3为主，玄武岩的水部分以碱土为主。
Abstract The Gedaref basin in eastern Sudan is believed to be a great tectonic depression filled mainly with continental deposits and Tertiary basalt lava flows. The main aquifers are the Gedaref sandstone aquifer system and the basalts. 70 wells drilled in the Gedaref basin were sampled and analysed for the major cations, major anions, total dissolved solids, alkalinity and hardness. The data were treated with simple statistics, represented with Piper trilinear plots and were the subject of cluster analysis. The interpretations of the applied methods confirm each other and the groundwater was classified into two groups. The water in the sandstone aquifer was dominated by NaHCO3 while the water in the basalts was partially dominated by alkaline earth.
