| 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 |
