摘　　要：1.Introduction Ultrahigh pressure(UHP) metamorphic rocks are widely exposed in continental collision zones,which usually occur as nappe units composed of coherent crustal materials.Their formation results from subduction and exhumation of the continental crust in subduction channels.However,the exhumation mechanisms for these UHP slices from deep to shallow crust are still controversial.Previous studies suggest two types of exhumation mechanism(Schmalholz et al.,2014;Zheng,2021).
