According to the hydrochemical characteristics, hydrogen and oxygen isotope characteristics, and the ratio of noble gas isotopes of the sandstone aquifer and basalt aquifer, this study calculates the recharge temperature and residence time of groundwater in Weishan area of Wudalianchi, and also calculates the contribution of noble gas components from different sources to the sample components. Based on the characteristics of hydrogen and oxygen isotopes and noble gases Xe and Ne, the recharge altitude and recharge temperature of the two aquifers are estimated, and the recharge temperature fits with the NGT model as verified, and the results show that the main recharge altitude of groundwater in the region is 500-600 m and the recharge temperature is 2-7 °C. He_eq and He_ea of the samples have been simulated by the OD model, the content of radioactive ⁴He in the crust was obtained, and the groundwater ages under the two conditions (closed condition and open condition) were simulated. The results show that groundwater from the sandstone layer water is older than groundwater from Basalt layer. Hydrochemical characteristics and noble gas isotope ratios indicate that in the basalt aquifer and sandstone aquifer in the Weishan area, in addition to atmospheric and crustal helium, there is also input of mantle-derived helium. The fault constitutes the uplifting channel for groundwater contains mantle components, which results in that the mantle source composition in water samples near the fault is much higher than those of non-fault areas.

东北五大连池微山地下水氢氧同位素及稀有气体同位素特征

根据砂岩含水层和玄武岩含水层的水化学特征、氢氧同位素特征、惰性气体同位素比值，计算了五大连池微山地区地下水的补给温度和停留时间，并计算了地下水的贡献度。来自不同来源的惰性气体组分到样品组分。根据氢氧同位素和稀有气体氙、氖的特征，估算了两个含水层的补给高度和补给温度，补给温度符合NGT模型，结果表明主要补给高度该地区地下水埋深500-600米，补给温度2-7℃。He _eq和 He _ea采用OD模型对样品进行了模拟，得到了地壳中放射性⁴ He的含量，并模拟了两种条件（封闭条件和开放条件）下的地下水年龄。结果表明，来自砂岩层的地下水比来自玄武岩层的地下水更古老。水化学特征和惰性气体同位素比值表明，在微山地区玄武岩含水层和砂岩含水层中，除大气和地壳氦外，还有地幔源氦的输入。断层构成地下水的抬升通道，含有地幔成分，导致断层附近水样的地幔源成分远高于非断层区。
