The curved structure is one of the common structural styles in orogenic belts. The formation process of the curved structural belt is of great significance to reveal the formation and evolution of orogenic belt. The geometric features of the curved structures are usually shown in five types on the flat surface：Parallel, convergent, divergent, cut and mixed. Curved structural belt can be divided into three kinematic models：Primitive arc, progressive arc and secondary procline, which are based on their kinematic histories and the timing of curvature acquisition. The formation of curved structural belts are closely related to geological conditions（such as edge of the terrains, obstructing of rigid blocks, thickness of stratum, slippage degree difference and strike slip faults etc.）, kinematic characteristics, geodynamic settings and multi period tectonic movements.
