文摘

We conduct geothermal modeling of the North China Craton based on 24 profiles. The mantle heat flow shows a marked decreasing trend from east to west of the NCC. Thermal lithosphere varies from <75 km in the east to >120 km in the west. The disparity between the thermal and seismic lithospheric bases increases westward. We inter a low-viscosity mantle wedge formed by dehydration of the Pacific slab.
