| 摘 要： | 采集夏县中心地震台温泉水及周边水点样品进行水化学组分特征分析。利用矩形图、Na-K-Mg三角图等方法，初步分析温泉水的水质类型、水-岩平衡状态、热储温度以及循环深度等，并结合氢氧同位素组成特征，初步分析温泉水补给来源。研究表明，夏县中心地震台温泉水化类型属于Na-Cl·SO4型，水-岩反应属于部分成熟水，热储温度为148.8℃，循环深度为3.91 km，补给源主要为大气降水，温泉为断裂型温泉。以上结果可为该台流体异常分析提供基础研究资料，为夏县地区水化研究奠定基础。

| Abstract: | The hydrochemical composition characteristic of spring water and surrounding samples is analyzed in this paper. The types, the state of water-rock reaction, the temperature of geothermal reservoir, circulation depth and supply sources of the Xiaxian spring water and surrounding samples were discussed by using rectangle hydrochemical diagram, the triangle diagram of Na-K-Mg and the stable hydrogen and oxygen isotopes. The result shows that the Xiaxian spring water belonged to Na-Cl·SO4 types, and the state of water-rock reaction belonged to partially mature water. The geothermal reservoir temperature of Xiaxian spring water is about 148.8℃ and the depth of the thermal cycle is about 3.911 km, which suggests that the thermal water in this area is supplied by the atmospheric precipitation mainly. The hot water is a fracture-type hot spring. These results can provide the basis data for the fluid anomalies of Xiaxian station and hydration research of this region. |
