Jiyang depression and Luxi uplift share the same type of crystalline basement.Three typical deep seismic reflection profiles acquired in these two regions during recent years were used to reconstruct the depositional burial history of the basin.By repeatedly matching the tectonic features of the basin

kinematic parameters during each main tectonic evolution stage were quantitatively calculated and the extensional process of the basement was analyzed in detail.The results show that both basement extension and fault activity are in temporal and spatial non-equilibrium in Jiyang depression and Luxi uplift

and the intensity of extensional deformation during Paleogene is much stronger than that during the Mesozoic for both of the regions.For Jiyang depression

both the ratio and rate of the Paleogene extension in N-S direction are two times bigger than those in E-W direction.This article provides an important basis for the further study of the tectonic evolution and crustal extensional deformation of the Great North China in Eastern China during the Meso-Cenozoic.
