新疆准噶尔盆地北部天然水的同位素研究及其应用

在对新疆准噶尔盆地北部天然水H、O同位素进行系统调查中运用同位素水文地球化学基本原理对该区不同水源类型的同位素组成进行了分析研究 ,确定了大气降水线方程和大气降水同位素高程效应 ,并对同位素蒸发效应、纬度效应和地下水形成年龄进行了探讨。这些研究成果对于阐明该区赋存铀资源的第三系砂岩含矿含水层中地下水补给来源、补给区高程和形成年龄以及论证铀成矿规律具有重要现实意义。

The Isotopic Study and Application of Natural Water in Northern Zhunggar Basin, Xinjiang

On the basis of the hydrogen and oxygen isotopic investigation of natural water from Northern Junggar basin in Xinjiang,the authors analysed and studied isotopic composition of different kinds of water sources in accord with basic principles of isotopic hydrogeochemistry,and determined the meteoric water line equation and the meteoric isotopic altitude effect,and probed into the isotopic evaporation,the latitude effect and the age of underground water.The results play an important role in demonstrating the recharge source,the altitude of the recharge area,the age of underground water in the uranium bearing Tertiary strata and the uranium metallogenic regularity.
