| 摘 要： | 对在延怀盆地采集的 14组 (次 )地下热、冷水和气体样品的分析结果表明 ,地下热水主要是大气降水成因的 ,其循环深度为 16 0 0～ 380 0m ,深部最高温度为 57～ 112℃ ,滞留时间为 50～30 32 0a ;热水中的稀有气体为大气、壳源和幔源成因 ;热水与气体在地震前的异常变化与热水所处的断裂构造及其活动性密切相关。关于该区地下热水的年龄和幔源气体的发现为首次报道 ,它对该区的断裂活动性、地震危险性研究和热水合理利用具有重要的意义 |
| 关 键 词： | 地球化学 热水 同位素 幔源气体 延怀盆地 |

| Abstract: | In the past several years, a series of geologic, seismologic, geochemical and geophysical investigations have been conducted to understand the crustal structure, activity of active faults and seismic risk in the Yanhuai Basin. During the investigations, a large number of data about the pre seismic, co seismic and post seismic behaviors of subsurface fluids have been obtained by the Seismic Precursory Monitoring Stations in the area. This paper deals with the geochemistry of groundwater and noble gase |
| Keywords: | geochemistry geothermal water noble gases mantle Yanhuai basin |
