摘      要：The thermal structure of the continental subduction zone can be deduced from high-pressure and ultra-high-pressure rock samples or numerical ***,petrological data indicate that the temperature of subducted continental plates is generally higher than that derived from numerical *** this paper,a two-dimensional kinematic model is used to study the thermal structure of continental subduction zones,with or without a preceding oceanic *** results show that the removal of the preceding oceanic slab can effectively increase the slab surface temperature of the continental subduction zone in the early stage of *** can sufficiently explain the difference between the cold thermal structure obtained from previous modeling results and the hot thermal structure obtained from rock sample data.
