摘要
The Shijiutuo Uplift is bounded by faults which controlled not only the boundaries of the uplift, but also the paleogeomorphic pattern characterized by a steep horst in the center and flat slopes outwards. Faulting was intensive at the center and gradually became weaker to the out sides. The structural pattern was obviously the main factor which controls the types of depositional system and the filling sequences. The results show that the distribution pattern of sedimentary facies of the Ed3 of the Dongying Formation in the study area is consistent with the paleogeomorphic features of a steep center surrounded by flat sides.
