Abstract: Depressedtype slope breaks was developed in the southwest and northeast margin of the LateTriassic Ordos Basin. In the northeast margin, the slope breaks were characterized by multistage and gentle, with grade of 13 and width of 15~25 km; In the southwest margin, the slope breaks were characterized by monolithic and steep, with grade of 35 and width of 10~20 km. Variations of slope breaks distribution were partly affected by the shrinkage of lake basin. However, slope controls formation overlapping, lithologic association and distribution of sedimentary system. To build distribution modeling of slopenonstructural trap based on the research of slope break characteristics plays an important role in exploration activity of the LateTriassic Ordos Basin.
