英文摘要The western North China Craton (NCC) entered a stage of craton thinning concentrated on its margin in the Cenozoic, but its Late-Cretaceous conditions were previously deduced to be relatively quiescent. Therefore, whether the Late-Cretaceous tectonic reactivation existed on the margin of this block is critical to understanding how the craton evolved into a thinned one. To investigate this possible margin reactivation in the Late Cretaceous, we apply zircon (U-Th)/He thermochronology to Taibai Mountain on the southern margin of the western NCC. From an similar to 3-km-high vertical profile with ages decreasing from 98 +/- 5 Ma at the peak to 52 +/- 7 Ma at the foot, the age-elevation relationship suggests the rapid exhumation at ca. 78-71 Ma bracketed by two slow exhumation phases. This interpretation is confirmed by 1D half-space modeling and QTQt inverse modeling, with the rapid exhumation stage having an exhumation rate of 0.1-0.6 km/Myr and a cooling rate of similar to 10 degrees C/Myr. Together with previously reported thermochronological data from the margin of the western NCC, the rapid exhumation at ca. 78-71 Ma implies a reactivated margin in the Late Cretaceous before widespread Cenozoic thinning of the craton margin. This Late-Cretaceous reactivation likely resulted from WNW-ESE extension expressed by thermo-tectonic events, basin subsidence, and volcanism in East Asia. Excluding impacts from climate change, lithospheric delamination, and India subduction beneath Eurasia, we infer that the Late-Cretaceous reactivation on the margin of the western NCC was driven by the far-field effect of Izanagi Plate subduction beneath the Eurasian Plate during slab rollback of the subducted plate.
