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。
In the systematic investigation of H and O isotopes of natural water in the northern part of Junggar Basin in Xinjiang, the isotopic compositions of different water sources in this area were studied by using the basic principles of isotope hydrogeochemistry. The equations of atmospheric precipitation and the isotopic elevation of atmospheric precipitation were established. The effects of isotope evaporation, latitude and age of formation of groundwater are discussed. These findings have important practical significance for clarifying the source of groundwater recharge, the elevation and age of recharge area and the regulation of uranium metallogenesis in Tertiary sandstone ore-bearing aquifers with uranium resources in this area.
