For the first time, we apply different geospeedometric models to get zoning patts that were obtained in this study from detailed EMP analyses for gets from eclogites and granulite in the Dabie-Sulu orogen. Various zonings of cation diffusion were preserved in the gets, enabling the acquirement of average cooling rates for the highto ultrahigh-pressure rocks without using geochronological approaches. The coesite-bearing hot eclogites yield fast cooling rates of about 20 to 30℃/Ma subsequent to peak metamorphic temperatures, whereas the cold eclogite gives a relatively slow cooling rate of 8℃/Ma at its initial exhumation. A very slow cooling rate of ＜0.3℃/Ma is obtained for the granulite at Huangtuling, suggesting that the granulite may not be involved in the continental deep subduction.
