| Abstract: | The recently developed U-Th/He dating technique has proved to be a most effective thermochronometer for studies of post-orogenic exhumation(timing and amount),landscape evolution and the thermal history of sedimentary basins. This paper first summarizes the basic principles and laboratory procedures of the He dating technique. Case studies are given for the application of the He dating technique in landscape evolution, post-orogenic exhumation and high-precision dating of younger rocks. |
