摘要
By taking noble gas samples and 14C samples in the same well from the Quaternary aquifers in Hebei Plain,the results revealed that the concentrations of radiogenic 4He components ranged from 5.43×10-8 to 8 994×10-8 cm3·STP/g by using closed-system equilibration (CE) model.Furthermore,it was found that 4He age of groundwater ranged from 8.8 to 55.9 ka and 14C age ranged from 7.7 to 35.2 ka,which indicated that above two results differed slightly and correspondingly the authors concluded that the application of 4He dating in Hebei Plain is reasonable.
