(U-Th)/He Thermochronology of Apatite and Its Application in Landform Revolution

The basic principle of apatite (U-Th)/He thermochronomety, dating method, model for correcting He age, closure temperature and the empirical studies, were described in this paper. Its applications in studies of paleo-geomorphology, exhumation history of orogens, and erosion rate were also described.
