Abstract: The development of U-Th/He dating method is reviewed, and the principle, the analysis progress and the long α-stopping distance correction of this method are briefly presented in this paper. Then, the achievement on He diffusion in apatite and its mathematic modeling and the application of U-Th/He dating method to palaeogeomorphy, rock uplift, and basin thermal evolution is summarized. Finally, we evaluate the advantage and disadvantage of the U-Th/He method. As a conclusion, we think that this method has good prospects as well as necessity to be improved.
