摘　　要：温泉是一种珍贵的理疗、旅游资源,其水化学特征对理疗热矿水评价和成因研究具有重要意义。四川省巴塘县措纳柯温泉所在地区具有丰富的旅游资源,目前尚未有关于该温泉较为详细的水化学数据报道。为助力措纳柯温泉开发利用和成因研究,采集措纳柯温泉代表性温泉水,进行水质简分析和微量元素分析,研究水化学特征,初步开展理疗热矿水评价,探讨温泉成因。研究结果显示:措纳柯温泉泉口温度介于50~65℃之间,其水化学类型属于HCO_(3)^(-)·Na型,温泉水具有较高含量的锂、锶、铷、铯、钨、硼、氟、偏硅酸和偏硼酸等组分,其中氟、偏硅酸和偏硼酸含量达到具有医疗价值或命名矿水的浓度标准,是良好的理疗热矿水,温泉主要利用方向为理疗、康养和采暖综合利用;措纳柯温泉热储温度介于107.56~119.01℃之间(均值114.30℃),属于非岩浆热源型的中温地热资源;周边高山区域的大气降水、冰雪融水沿近SN向断裂带和NEE向断裂裂隙带循环到深部3300 m左右较高温度的区域,被途径岩石加热,并与富锂花岗岩发生较强的水-岩反应,形成富Li、Rb、Cs、B和Cl等元素的地热水,地热水沿裂隙带上升形成温泉。Hot springs are a precious resource for physical therapy and tourism,and their hydrochemical characteristics are of great significance for the evaluation and genesis research of thermal mineral water in physical therapy.The area where Cuonake hot spring islocated in Batang county,Sichuan province,has abundant tourism resources,and there are currently no detailed hydrochemical data reports on this hot spring.In order to help the development and utilization of Cuonake hot springs and the study of their genesis,this article collected representative hot spring water from Cuonake hot springs,conducted water quality measurement and trace element analysis,studied hydrochemical characteristics,conducted preliminary evaluation of physical therapy hot mineral water,and explored the genesis of the hot springs.The research results show that the temperature at the mouth of Cuonake hot spring is 50~65℃,and its hydrochemical type belongs to the HCO_(3)^(-)·Na type.The hot spring water has a high content of lithium,strontium,rubidium,cesium,tungsten,boron,fluorine,metasilicic and metaboric acid components.Among them,the fluorine,metasilicic acid,and metaboric acid content meet the concentration standards of medical value or named mineral water,making it a good physical therapy hot mineral water.The main utilization direction of hot springs is comprehensive utilization of physical therapy,health care,and heating.The thermal storage temperature of Cuonake hot spring ranges from 107.56 to 119.01℃(with an average of 114.30℃),and it belongs to a medium temperature geothermal resource of non magmatic heat source type.The atmospheric precipitation and melting water of ice and snow in the surrounding mountainous areas circulate along the nearly north-south trending fault zone and the northeast trending fault fracture zone to a higher temperature depth of about 3300 m.They are heated by passing rocks and undergo strong water rock reactions with lithium rich granite,forming geothermal water rich in Li,Rb,Cs,B,Cl and other elements.
