Bengbu uplift tectonic is located in the southeastern margin of North China Craton （NCC），the southernmost of Jiao-Liao-Ji orogenic belt，and its mainly composed of Wuhe complex. Previous studies in this area mainly focused on isotope chronology and metamorphic P-T conditions. The metamorphic P-T conditions were quite different，with the most significant change in pressure and there was a lack of unified understanding of the P-T conditions of peak metamorphism. In this paper，a large amount of petrographic and mineral chemical composition analysis of garnet pyroxenite in Bengbu uplift has been carried out，indicating that this rock has record 3 metamorphic stages，in which the mineral combinayion of S-M1 and S-M2 is similar to Grt+Cpx+Opx+Amp+Pl+Ilm and the mineral combinayion of S-M3 is Cpx+Amp+Pl+Grt （extremely narrow band）. Taking metamorphic P-T conditions and zircon U-Pb chronology result into consideration，the following conclusions are drawn: 1） The garnet pyroxenite sample WS047-1 recorded three metamorphic stages，temperature and pressure conditions respectively: T-M1 = 616 ℃～647 ℃ and P-M1 = 1.03～1.08 GPa，T-M2 = 721 ℃～837 ℃ and P-M2 = 1.11～1.29 GPa，T-M3 = 531 ℃～607 ℃ and P-M3 = 0.81～ 0.91 GPa. It was showing a recycle from high-pressure amphibolite facies，granulite facies to amphibolite facies. 2） According to the analysis of metamorphic P-T conditions，Bengbu uplift has a clockwise P-T paths，and S-M1→S-M2 and S-M2→S-M3 are revealed a slowly process from near isobaric heating to isobaric cooling. 3） The U-Pb geochronology of zircon can be divided into 4 groups: 1 839±13 Ma，1 925±31 Ma，2 041±55 Ma and 2 762±14 Ma，and the peak metamorphic zircon age is 1.93～1.84 Ga. 4） Combined with the study of P-T conditions and chronology，the paper draws a conclusion that Bengbu uplift is similar to that of Francisco-type subduction or continental collision environment，which should be consistent with the collision and combination of the east and west blocks of North China Craton from 1.93 Ga to 1.84 Ga and the formation time of the Jiao-Liao-Ji belt. This study provides a large amount of reliable scientific data for further understanding the structural evolution characteristics of the North China Craton and the metamorphism and evolution of Bengbu uplift.
