| 摘 要： | 地表水热活动常伴有通量不等的气体释放，作为水-岩反应和地球深部脱气的产物，泉气的化学和同位素组成因其热储所处的大地构造单元、岩性和应力状态的差异而有所不同。对泉气化学和同位素组成时空变化的观测和研究是了解地壳-岩石圈动力学的重要方面，有助于地震、火山活动等地质灾害的监测和地热资源的开发利用。 |
| 关 键 词： | 水热系统 泉气 稀有气体 同位素 |

| Abstract: | Hot spring water and gases are always concomitant and the fluxes of gases released from different geothermal systems are various. As a results of water rock reaction and degassing from the deep,the chemical and isotopic composition of geothermal spring gases are diverse because of different settings of the geothermal reservoir in the aspect of tectonic position, lithology and stress status. It is of significance to study the spatio temporal changes of chemical and isotopic component of hot sprig gases and that may help us realize crust lithosphere kinetic status. Furthermore, there will be application foreground in the monitoring or predicting earthquake and volcano activity as well as geothermal exploitation and utilization. |
| Keywords: | Geothermal system Gases of thermal spring Noble gas Isotope |
