Kongque slope is located in the northeastern part of Tarim Basin, and its formation is closely related to the south Tianshan and the Altun Mountains. Yuli fault nose-shaped structure, located in the northwestern part of Kongquehe slope, completely records the tectonic evolution of Kongquehe slope, the interpretation and analysis of the fault nose-shaped structure is very important to reveal the geodynamic settings of the northeastern margin of Tarim Basin since Early Paleozoic. Through the fine interpretation of the seismic profile across Yuli fault nose-shaped structural zone, using the theory of fault-related fold, this paper analyzed the tectonic features and the formation and evolution of the fault nose-shaped structure, and discussed the genetic mechanism.
