英文摘要	Jurassic tectonism resulted in late Mesozoic intracontinental deformation of the North China Plate. A fold-and-thrust belt, related growth strata, and volcanic materials have been identified in the Jurassic Yungang Basin, which can be used to constrain the timing and scale of faulting and sedimentation. The age of volcanic materials in the growth strata and the sedimentary cycle of Jurassic strata indicate that the late Middle Jurassic Yungang Formation was the earliest sedimentary response to the onset of Jurassic deformation (i.e., the Yanshanian orogeny) from 170 to 160 Ma. Deformation involved detachment and fault propagation folding, which produced a marginal thrust belt and limb rotation of anticline. Restored cross-sections show that the northern basin experienced more intense shortening than the southern basin, consistent with field observations, possibly controlled by the Qifengshan strike-slip fault in the center of the fold-and-thrust belt. Fault striations, conjugate joints, and asymmetric folds show that the Yungang Basin underwent NW–SE-trending compression during the Middle–Late Jurassic. Therefore, we propose that the eastern Ordos Block was in a compressional setting during the Middle–Late Jurassic, due to flat subduction of the Paleo-Pacific Plate beneath the East Asian continent. © 2020 Elsevier B.V.
