| 摘 要： | 陕西渭北东部岩溶地下水的水化学和同位素研究表明,水中硫酸盐起源主要为海相硫酸盐的溶解,其次为南部泻湖相古沉积咸水的混入。岩溶地下水中的盐分的增加主要是溶滤作用的结果。

| Abstract: | A composition of isotope and chemical data of the groundwater in the eastern Weibei karst area indicates that the sulfate in the groundwater of study area mainly form from marine sulphate dissolves. Secondly the age-old deposit salt water is interfused into the groundwater from the south. The higher salinity in groundwater is resulted from the dissolving action. |

| Keywords: | groundwater sulfur isotope salt mechanism dissolves action origin of sulphate |
