中国东部温泉水和井水的氢氧同位素初步研究

Study on Isotope Hydrogen and Oxygen of Hot Spring Water and Well Water in the East of China

对安徽、山东、辽宁的几处温泉水和井水的氧和氢同位素进行了对比研究,发现温泉水的氧和氢同位素值都低于井水的氧和氢同位素值。温泉水和井水的氧和氢同位素值都落在大气降水线附近,与Craig所作的大气降水线较为吻合。这一结果说明该地区温泉水和井水的补给源都来自大气降水。温泉水的δ^(18)O值变化范围很小,说明δ^(18)O值可能受该地区地质构造控制。温泉水和井水氧和氢同位素值具有明显的纬度效应,它们的氧和氢同位素值随纬度的增大而增加。

Contrastive studies are carried out on the hot-spring water and well water from several places in the provinces of Anhui, Shadong and Liaoning for isotopes of hydrogen and oxygen. It is found that recharge sources of hot-springs and wells have a certain relationship in the areas. Hot-spring water and well water come from meteoric water in the areas. The value of Oxygen-18-of an area may be due to its geological structure.
