【摘要】 天津及邻近地区自 １９６６ 年 ３ 月６ 日至今卅余年的时间内先后发生了邢台、渤海、唐山三次 ７ 级以上大地震和十余次 ６ 级中强地震，为研究该区的水文地球化学环境提供了有利条件，作者依据该区域内 ３９２ 口井，５０００ 多个水样，２０ 余个项目的分析资料，探讨了中强地震震源区水文地球化学环境与特征，为探索利用水文地球化学方法判定潜在震源区开辟了新的途径更多还原

【Abstract】 Three earthquakes of magnitudes over 7 and more than 10 earthquakes of magnitudes over 6 occurred in Tianjin and its vicinity since the 1966 Xingtai earthquake,it provides favorable conditions for studying the circumstance of hydrogeo-chemistry.The authors have approached the features and the hydrogeo-chemistry circumstances of the moderately strong earthquakes on the basis of the data of 392 wells and over 5000 water sampoles,our research explores a new way to determine the potential seismic region by using the method of hydrogeo-chemistry.更多还原
