There are three periods main faults in the southern North China Basin. The first period faults are thrust faults because of compressive stress in Late Triassic, with near EW trend, thrusting direction from south to north. The second period faults are strike slip faults mainly trending NNE caused by tensional-shear stress in Late Jurassic-Early Cretaceous. The third period faults are a series of normal faults mainly trending NNE related with the structural movement in Late Cretaceous and Paleogene. Thrusting and uplifting of the faults in Late Triassic resulted in serious erosion and discontinuity to Carbon-Permian source rocks. The faults in Late Jurassic-Early Cretaceous and the faults in Late Triassic cut the southern North China Basin just as chess board, and the igneous rock associated with the faults destroyed the source rocks in a certain degree. The faults in Late Cretaceous and Paleogene reinforced the discontinuity of source rocks. The faults in later two periods usually reached the land surface and destroyed the oil and gas reservoir formed before Late Jurassic. Therefore, the oil and gas exploration in the southern North China Basin should avoid the strike slip faults, normal faults and igneous body, search for the Paleozoic source rocks of good continuity, hunt for the sedimentary facies belts in favor of developing source rocks.
