【摘要】 本文通过多种方法对车田湾热泉的水、热来源和循环途径进行了探索性的研究 ,除采用综合地质及同位素分析方法外 ,还引入了近年发展起来的碳循环研究方法。结果显示 :该区热泉 (群 )的水来源于大气降雨 ;碳同位素分析结果则显示 ,热水中碳的来源与深部关系不密切 ;钻孔测井资料显示 ,水、热的强循环深度在 60 m和 80～ 10 0 m。由于各泉或钻孔所处的岩性、地质构造和水文地质条件不同 ,因此它们在水化学及其动态特征、同位素特征等方面具有一定差异更多还原

【Abstract】 Through the geological,hydrogeological,tectonic and isotopic analysis,we have made a study on water and heat sources and circulation processes of some geothermic springs in Ziyuan county,Guangxi.The results show that rainfall is the only sourceof hot spring water,and the distribution of the springs have a close relationshipwith the geological structure which enables the the geothermic energy to transport upward.The results of physical measurement to the bore holes indicate that the most active circulation depth of the springs is 60~100m where we measured water temperature and quantity.The hydrochemical data show that there are some hydrochemical, dynamic and isotopic differences among these geothermic springs.更多还原
