| 摘 要： | 通过对王兰庄、山岭子、塘沽、武清、大港及周良庄等地热田的勘查，文章对天津地区的地热形成机理进行了研究，分析了在华北地台大的构造演化过程中，造成本区上地壳花岗岩顶板埋深变浅以及厚度的增加，具有足够丰度、半衰期较长的放射性元素蜕变生成热聚集形成地球内部的增温；古老的地盾与较为活动的冒地槽之间的地台上较高的上地幔热流得以在较短的路径上向外传递。得出结论：天津地区属于地热正常区，只有在一定的构造条件和水动力条件下，才能形成局部的地热异常区。 |

| Abstract: | Geothermal resource is very widespread in Tianjin of China. Its exploration and development have had a long history about some decades. Tianjin Geothermal Exploration Developing and Designing Institute have explorated Wanglanzhuang, Shanlingzhi, Tanggu, Wuqing, Dagang and Zhouliangzhuang geothermal fields. A lot of achievements were obtained. The mechanism of geothermal origin has been studied related to the evolution of North China Plate. Tianjin is normal geothermal area. Geothermal hydrodynamic conditions. anomaly is formed due to geological structure and |
