Dabieshan%extension%(U-Th)/He thermochronology
(U-Th)/He ages of 13 samples from Yuexi-Luotian core and its flanks in Dabieshan orogen fall in the range of 155～85 Ma. He ages for samples from the core range between 85～107 Ma, while those from the flanks range between 114～155 Ma. The result shows that the Yuexi-Luotian core was a thermal dome in Cretaceous with core temperature being much higher than those of the flanks. The thermal extension which resulted in the formation of Dabie core complex lasted until ca. 85 Ma. The magnitude of exhumation in the core is approximately 1528.8 m more than that in the flanks.
