Differential uplift between Beihuaiyang and Dabie orogenic belt

Isotope dating, hornblende geobarometer, fission-track analysis and fluid i nclusion 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 DOE since late Paleozoic era. BHY had experienced three stages of upli ft (C1-C2, T-J2, J3-K1) and its total uplift height is about 10 km, but, DO E had only experienced two stages of uplift (T-J2, J3-K1) and its maximum u plift height is more than 15 km. BHY uplift occurred mainly before the mid- Jurassic (about 150 Ma), but DOE uplift took place after the mid-Jurassic ( about 150 Ma).
