| 摘 要： | 河北遵化汤泉地热资源丰富，阐明其成因模式对于该地热田的进一步开发和热水资源的可持续利用具有一定的指导意义。基于地温测量和水文地球化学分析等方法对其进行了系统研究，结果表明该地热田属中低温对流型地热系统。地热田在其以北的山区接受大气降水补给，补给高程下限约为935 m。地热流体在深循环过程中于正常的大地热流背景下被围岩逐渐加热，热储温度约为130 ℃，循环深度约为4 800 m。在汤泉福泉宫至疗养院一带，构造切割花岗岩体，使得深部地热流体沿破碎带上涌，混合并加热赋存于蓄水构造中的片麻岩裂隙水，形成汤泉地区的地热异常。

| Abstract: | Tangquan is located in the northwest of Zunhua city, Hebei Province. The region is of hilly landscape, and rich in geothermal resources. It is of great importance to elucidate the genesis mechanism of the geothermal field for sustainable development of the geothermal resources. In this paper, we conducted a systematic study to explore into the genesis mechanism through well temperature logging and hydrogeochemical investigation. Results show that the geothermal field belongs to a low to medium temperature geothermal system of convective type. The geothermal fluid origins from the rainfall recharged in the mountainous area located to the north of geothermal field, with a recharge elevation of more than 935 m. The geothermal fluid is gradually heated by the surrounding rock under a normal heat flow background during a deep cycling of ca. 4,800 m, with a reservoir temperature of ca.130 ℃. In the zone of Fuquan palace to sanatorium in Tangquan area where several faults cut through the monzonitic granite body, the geothermal fluid up flow along the faults and mix with the fissure water stored in the gneisses, forming the Tangquan geothermal field. |
