The slope belts are widely distributed, and basin slope belts play a crucial role in studying the geological movements, tectonic evolution, and fracture combinations within basins. The investigation of the morphology of basin slope belts contributes to a better understanding of the structural characteristics and geological features within basins. This paper employs the Discrete Element Method (DEM) numerical simulation to study the influence of different morphologies of basin slope belts on the development of secondary faults during extensional movements. Simulation results indicate: During the extension process, secondary faults tend to develop in the hanging wall strata controlled by the basin slope belt and above the location where the slope of the basin slope belt changes. Under the influence of shovel-shaped slope belts, the developed secondary faults exhibit different orientations. In contrast, under the influence of ramp-flat slope belts, the developed secondary faults mostly share the same orientation. Ultimately, the comparison of the discrete element simulation results with the east-west profiles of the Xinzhen structure in the Dongying Depression adds practical significance to the simulation.
