摘要
Dating groundwater with 14C needs a variety of calibrations.Groundwater 14C age is calibrated with TDIC(Total Dissolved Inorganic Carbon) in North China Plain according to the results of systematic determination of 14C concentration. According to the distribution of deep groundwater 14C calibrated age and Cl-content, deep groundwater is obviously affected by seawater intrusion in North China Plain. The groundwater calibrated 14C age represents the real age for the west side of Hengshui-Hejian-Renqiu, but not the case for the east side of Hengshui-Xianxian-Tianjin because it presents a kind of mixture age of deep groundwater and seawater.
