Abstract: Correction of groundwater 14C dating is the hot spot in the research on groundwater dating. The coupling of inverse geochemical reaction path model and isotope mass transfer model can be completely involved in the effects of different carbon sources and different hydrogeochemical reactions on 14C mass transfer, which has made the correction technique of groundwater 14C dating in a new state. Identification of the main factors and their extent affecting the concentration of 14C in the groundwater evolution is of high importance for the accuracy and reliability of groundwater 14C age correction result. The specific character of recharge environment and the removal of nonpossible solutions should be paid more attention in application of inverse geochemical modeling in the correction of groundwater 14C da-ting.

Key words: inverse geochemical modeling, correction of groundwater 14C dating, accuracy and confidence, advances
