| 摘 要： | 对西藏盐井地区盐泉、曲孜卡泉、地表水及重要地层进行了同位素测定和分析,结合区域地质构造条件、辅以水化学证据确定泉水的补径排模式。δD~δ18O规律指示出盐泉和温泉的补给类型的差异;用δ18O对泉水的补给区海拔高程进行恢复;泉水、岩样的δ13C~δ18O规律指示出盐泉流经的主要相关层位为上三叠统地层T3b~T3d;其排泄主要受到芒康-盐井复式向斜次级背斜核部的张性裂隙所控制。

| Abstract: | Based on the analysis results of isotopes and the geological environment,the circulation mode of salt spring water is confirmed under the Earth.The stable isotopes of 18O,D and radioactive isotopes of 3H in the spring water can give proof about the type of supply water and blending conditions.Also,the altitude of supply water can be confirmed if the supple water is rain.The relationship between 13C and 18O can provide some information about water-rock reactions,and the correlative stratum where the spring f... |
