Abstract

Abstract

Based on plenty of three dimensional seismic data, the horizontal and sectional characteristics of three main strike-slip faults in detail in the eastern Liaodong Bay Depression are described. Different faults have different characteristics and even the same fault has segmented differential features. The overall degree of strike-slip gradually increased from east to west, from north and south to the middle. With the method of physical modeling test, the strike-slip displacements of three main strike-slip faults in the eastern Liaodong Bay depression are estimated. The results show that the strike-slip displacement of Liaozhong Area is larger than that of Liaodong Area, and the strike-slip displacement and average strike-slip speeds of three strike-slip faults are the maximum in the Oligocene, illustrating there were strong strike-slips in the Oligocene.
