秦皇岛市抚宁县大泥河地下热水主要赋存于太古界单塔子群白庙子组变质岩中,水化学类型为Cl—Ca·Na型水,水化学成分与温度密切相关,水中可溶SiO2含量、F-含量较高,与水温呈正相关关系,由离子特征系数推测地下水的形成机制。
The underground hot water of Datunhe River in Funing County of Qinhuangdao City mainly occurs in the metamorphic rocks of the Baimiaozizi Formation of the Bogata Group in the Archeozoic. The hydrochemical type is Cl-Ca · Na type water. The chemical composition of water is closely related to the temperature and is soluble in water SiO2 content and F-content are higher, and have a positive correlation with water temperature. The formation mechanism of groundwater is deduced from the ion characteristic coefficient.
