| 摘 要： | 胶东半岛位于欧亚板块与太平洋板块边缘内侧 ,是地壳长期稳定缓慢隆起地段 ,区内地质构造发育 ,大部分温泉出露在背斜核部 ,NE、NNE向与NW、NNW向断裂交汇处。地热系统属中低温深循环对流型 ,略为偏高的大地热流是其主要热源 ,地表水是地下热水的补给水源 ,地下水通过发育在花岗岩和变质岩中的断层或断裂破碎带 ,下渗和深循环对流 ,在径流过程中不断吸取围岩热量成为热水 ,沿断裂上升过程中 ,与地下浅部裂隙水混合而成为化学成分各异 ,温度高低不等的温泉水

| Abstract: | Being located at the inside edges of Eurosia and pacific plates,Jiaodong Peninsula is a relatively stable upwarded district .Most of the warm springs are mainlydistributed in the cores of anticlines,and the intersections of fractures in the NE ,NNE and NW,NNW directions.Geothermal system,with the low medium temprature deep circulation convective type, was heated by normal to relatively high heat flow.Surface water is the supply resource of ground hot water.The groundwater runs through faults or fracture zones developed on granite and metamorphite,infiltrate and deep-circulates,absorbs continuously the heat from the wall rocks in the runoff process,then turns into hot water.The hot water goes up along fratures,mixes together with the crevice water in upper strata,and becomes warm spring water of different chemical compositions and temperatures. |
