%X The Dabie Orogen and its "foreland" result from Triassic collision of the North China Continental Block to the Yangtze Block. This research reveals that the "foreland" is in fact one fold-thrust fold belt related to the evolution of the Jiuling Basement Uplift Zone in the Central of the Yangtze Block. Combined with magnetotelluric sounding data, wide-angle reflection, seismic refraction, P-wave tomography, seismic reflection imaging of the MOHO surface, it reveals that the crustal architecture has difference between the upper and the lower crusts, like fish-bone shape based on rock properties, velocity, MOHO offset and deformation. It is deduced that the south-directed thrusting in the deep of the north Yangtze Block is closely related to the exhumation of the HP-UHP rocks of the Dabie Orogen based on surface geology and the mentioned-above architecture. However, the shallow structures are opposite thrust style composed of the north-directed thrusts of the north Yangtze Block and the south-directed thrusts of the Dabie Orogen. At last, the tectonic evolution and setting and deformation regimes are discussed and analyzed in this paper.
