前 言 最近两年中,我们研究了英国诺福克北部布尔河上游白垩系的白垩和上覆第四系冰碛物含水层中地下水的地球化学演变。为了进一步弄清水文地质条件和水文地球化学演变之间的关系,我们研究了该区地下水中的稳定同位素水文地球化学特征。 研究区位于东经1°—1°14′和北纬52°47′—54′(图1)面积为80平方公里。上白垩系的白垩层厚达450米,上复着第四系漂砾粘土和砂砾石冰碛物,其厚度达40—45米。白垩地面受内外营力作用尤其是冰川作用而得到改造,因此“通道”谷地,浅溶蚀坑和小型盆地很发 In the last two years, we studied the geochemical evolution of groundwater in the Cretaceous chalk and upper Quaternary moraine aquifers in the Upper Boer River in northern Norfolk, England. To further clarify the relationship between hydrogeological conditions and hydrogeochemical evolution, we studied the stable isotope geochemical characteristics of the groundwater in the area. The study area is located at an area of ​​80 km 2 between 1 ° -1 ° 14 ’east longitude and 52 ° 47’-54 ° north latitude (Figure 1). Cretaceous Upper Cretaceous 450 meters thick, up on Quaternary boulder clay and sand gravel moraine, the thickness of 40-45 meters. The chalky ground was transformed by the internal and external hydrodynamic effects, especially the glacier effect, so the “channel” valleys, shallow eroded pits and small basins
