摘　　要：以天津塘沽馆陶组Ⅲ段底砾岩热储层地热系统为例 ,根据 13个监测点所测的放射性同位素1 4C资料 ,计算了地热水的年龄。在分析地热水年龄的平面和垂向分布规律的基础上 ,推断了西部的沧东断裂及北部边界的性质 。The method using radioactive isotope 14 C observation data to estimate the age of geothermal water is proposed.The conglomerate groundwater reservoir of lower Guantao Ⅲ Formation in Tanggu geothermal field of Tianijing City is analyzed as an example for demonstration of the method.On the basis of the analysis on age and distribution of the geothermal water,the properties of Cangdong fault and the burial fault in the west and north boundary are clarified.The result is verified by available geothermal geology and hydrology data.
