摘要
The slope-break belts are well developed in Middle Permian in Ke-Bai Area. Characterized by multiple orders along the source direction, they can be divided into basin-margin slope-break belts and inner-basin ones according to their respective natural geographical locations. In this paper, a reasonable model that slope-break belts control the formation of lithostratigraphic traps has been established. It is considered that the lithological traps, stratigraphic overlapping traps and unconformity surface-seal traps may be developed near the slope-break belts.
