摘要
为了解香格里拉地区的地热资源状况,以天生桥温泉和下给温泉为研究对象,利用水化学分析法、氢氧同位素分析法以及地热温标法,对天生桥温泉和下给温泉地热系统的水化学特征、地下水补给来源以及热储温度进行了分析.结果表明:天生桥温泉水化学类型为HCO3-Ca·Na和HCO3-Na·Ca型,下给温泉为HCO3·Na和HCO3-Na·Ca型;天生桥温泉和下给温泉均来源于大气降水,且存在18O漂移现象,其补给高程分别为3710m和3 842m,位于温泉东南方向的刺那一带,补给温度分别为-11.98℃和-12.91℃,均为未成熟水;天生桥温泉和下给温泉混合的冷水比例分别为52％和72％,利用SiO2地热温标法计算得到热储温度分别为98℃和160℃.
Abstract
In order to understand the status of geothermal resources in the Shangrila Region,the Tianshengqiao Hot Spring and Xiagei Hot Spring were taken as research objects.Water chemistry analysis,hydrogen and oxygen isotope analysis,and geothermal temperature scale method were used to analyze the hydrochemical characteristics of the geothermal system,groundwater recharge sources,and thermal storage temperature of Tianshengqiao Hot Spring and Xiagei Hot Spring.The results indicate that the hydrochemical types of Tianshengqiao Hot Spring are HCO3-Ca·Na type and HCO3-Na·Ca type,while the Xiagei Hot Spring are HCO3·Na type and HCO3-Na·Ca type.Both Tianshengqiao Hot Spring and Xiagei Hot Spring are sourced from atmospheric precipitation and exhibit 18O drift phenomenon.The recharge elevations are 3 710 m and 3 842 m,respectively,located in the southeast direction of the hot springs in the area of Shina.The recharge temperatures are-11.98℃and-12.91 ℃,respectively,and both are immature water.The proportions of cold water mixed in Tianshengqiao Hot Spring and Xiagei Hot Spring are 52％and 72％,respectively.The thermal storage temperatures calculated using the SiO2 geothermal temperature scale method are 98℃and 160 ℃,respectively.
