英文摘要	The uplift and deformation styles of the Tibetan Plateau have been long debated on stepwise growth and crustal channel flow. Here, we offer new insight into this issue by constraining the pulsed exhumation history of the Yalong thrust belt in eastern Tibet, using apatite and zircon (U-Th)/He data from three similar to 1 km vertical transects. The results revealed two rapid cooling pulses in the Late Oligocene (similar to 24 Ma, 50 degrees C/m.y.) and the Middle Miocene (17-14 Ma, 35 degrees C/m.y.), respectively, which we ascribe to the staged-thrusting faulting of this belt. These thrust faulting events indicated upward and eastward growth of the Tibetan Plateau, further suggested that the high topographic relief across the Yalong thrust belt mainly formed (at least) since the Late Oligocene. The available documents from paleoaltimetry, basin sediment accumulation, and thermochronometers and our new results reveal a regional-scale stepwise propagation pattern of tectonic deformation during the Middle-Late Cenozoic in eastern Tibet.
