全安盆地水文地质特征及热水成因分析
|
摘要
在简要分析全安盆地水文地质特征、地下水赋存条件及划分地下水类型基础上,对盆地西部周地—暖水塘地区地下热水形成原因、赋存环境进行研究,认为多期次构造运动形成的断裂、裂隙沟通深部地下热水是盆地热水来源的主要原因;采取地下热水样品并开展氢氧稳定同位素、逸出气体、水化学成份测试,认为地下热水由大气降水补给,长期水动态观测结果也显示大气降水与地下热水关系较密切。
Based on the analysis of hydrogeological characteristics,groundwater storage conditions and division of groundwater types,this research analyze the cause and conditions of geothermal water in Zhoudi-Nuanshuitang area in the western of Quan'an basin. The result shows that the connectivity between upper and bottom layers of geothermal water by the faults caused by poly-period secondary tectonic movement was the main source for current geothermal water. Then,the groundwater was sampled and analyzed by stable H-O isotope technique,escaping gas detection and water chemical composition test,the results indicate that water form atmospheric precipitation was the supply source of the geothermal water. These results also can support by a long-term water dynamic observation,which believe that a close relationship between geothermal water and precipitation.
