英文摘要	Granites sampled from Garzd-Litang thrust, Longmen Shan thrust, Garzd and Litang strike-slip faults in the eastern Tibetan Plateau have been analyzed with apatite fission track thermochronological method in this study. The measured fission track apparent ages, combined with the simulated annealing modeling of the thermal history, have been used to reconstruct the thermal evolutionary histories of the samples and interpret the active history of the thrusts and faults in these areas. Thermal history modeling shows that earlier tectonic cooling occurred in the Garzd-Litang thrust in Miocene (similar to 20-16 Ma) whereas the later cooling occurred mainly in the Longmen Shan thrust since similar to 5 Ma. Our study suggests that the margin of eastern Tibetan Plateau was extended by stages: through strike-slip faults deformations and related thrusts, the upper crust formed the Garzd-Litang margin in the Miocene epoch and then moved to the Longmen Shan margin since similar to 5 Ma. During this process, the deformations of different phases in the eastern Tibetan Plateau were absorbed by the thrusts within them and consequently the tectonic events of long-distance slip and extrusion up to hundreds of kilometers have not been found.
