Isotope dating,hornblende geobarometer,fission-track analysis and fluid inclusion homogeneous temperature analysis have been applied to Caledonian,Variscan and Yenshan plutons in Bei Huaiyang (BHY) and Dabie orogenic belt (DOB),and the emplaced depths and ages of these plutons have been obtained in order to obtain differential uplift time and uplift heights between BHY and DOB since late Paleozoic era.BHY had experienced three stages of uplift (C1-C2,T-J2,J3-K1) and its total uplift height is about 10 km,but,DOB had only experienced two stages of uplift (T-J2,J3-K1) and its maximum uplift height is more than 15 km.BHY uplift occurred mainly before the mid-Jurassic (about 150 Ma),but DOB uplift took place after the mid-Jurassic (about 150 Ma).
