摘要
本文研究了张家口南部地区温泉 (井 )水的氢氧稳定同位素组成及溶解气体组分特征。结果表明 ,大气降水是该区温泉 (井 )水的补给来源。大气降水在深循环过程中 ,受地热增温 ,岩浆残余热的影响 ,使水温增高并在适当的构造部位涌出地表形成温泉。
The hydrogen and oxygen stable isotopic composition and dissolved gas components of the hot spring (well) water in the southern area of Zhangjiakou are studied. The result indicates that the hot spring(well) water was originated from meteoric water. In the process of its deep\|cycling, meteoric water was affected by geothermal gradient and magmatic excess heat. As a result water temperature was increased and hot spring was formed when the heated water ascended to the surface in some suitable tectonic positions.
