Reactivated margin of the western North China Craton in the Late Cretaceous: Constraints from zircon (U-Th)/He thermochronology of Taibai Mountain

We report zircon (U-Th)/He thermochronology of Taibai Mountain, central China. Based on these data, we infer rapid exhumation of Taibai Mountain at ca. 78-71 Ma, which is confirmed by the age-elevation relationship, 1D half-space modeling, and QTQt modeling. Synchronous Late-Cretaceous rapid exhumation suggests a reactivated margin of the western North China Craton before Cenozoic thinning. This reactivation was triggered by the far-field effect of Izanagi Plate subduction beneath the Eurasian Plate.
