Abstract: The origin of structures in central Sichuan area is discussed according to its structural characteristics and the regional tectonic setting of Sichuan basin. It is considered that the structure in central Sichuan area are formed under the regional tectonic stress of Sichuan basin and the local stress derived from the basement structure and different properties during Himalayan tectonic movement. It could be divided into such two stages as the early S-N compression stage and the middle-late NE- -SW compresso-shear stage.

Key words: Sichuan basin, central Sichuan area, structure, origin
