本文描述并讨论了青藏高原东北部西宁盆地部分地热泉或地热井中采集的样品的水化学和同位素特征。威尔斯。结果表明，西宁盆地不同构造单元的地下水径流量、循环深度、补给期和滞留时间差异很大，对热储温度和保温性起主导作用。特别是，年轻的冷地表水的补给迅速，大大降低了地热系统的温度。在热源方面，总体低温、未成熟沃茨和氦同位素（3 He/4 He和4 He/20 Ne）表明，似乎没有热的地幔源流体来提高地温。地壳岩浆流体、放射性元素的放射性生热和断层摩擦生热都可能是西宁盆地热源的贡献因素。因此，今后的地热资源勘探应向拉脊山深大断裂带的北方边缘靠近，该断裂带具有较高的热流量，可提供热源，而地表水与地下水的混合相对缓慢。
This paper describes and discusses the hydrochemical and isotopic characteristics of samples collected from some geothermal springs or wells in the Xining basin of the northeastern Tibetan Plateau, China. The results show that the groundwater runoff, circulation depth, recharge period, and residence times vary greatly, while dominating both the geothermal reservoir temperature and heat preservation in different tectonic units of the Xining Basin. Particularly, recharge by young cold surface water quickly and greatly reduces the temperature of geothermal systems. As for heat source, the general low temperature, immature waters as well as, helium isotope (3He/4He and4He/20Ne ratio) show that there seems to be no hot, mantle sourced fluids to increase the geothermal temperature. Crustal magmatic fluids, the radiogenic heat of radioactive elements, and the fault friction produced heat can all be possible contributing factors to the Xining basin heat sources. One can conclude that future investigation for geothermal resources should be closer to northern margin of Laji Moutain deep large fault zone where the high heat-flow can provide heat source while the mixing of surface water with groundwater is relatively slow.
