The Sichuan Basin is a kind of classic cratonic basin having undergone multi-stage evolution, and is rich of gas resources in the different sets of sedimentary sequences. Considering the adjacent plate tectonic evolution, and combing the basin depositional filling with the developing of the peripheral orogenic belts, the paper takes advantage of using the newly released data on surface geology, drilling, gravitational and magnetic, and seismic profiles to address the basin evolution history and its superposed processes of Sichuan Basin and around area. The basin cycles had resulted in the horizontally combination and vertically superimposition of proto-type basins, producing a distinct kind of geological structures called as stratified and blocked. Influenced by the multi-periods of interaction between the basin and the orogenic belts, the stratified and blocked basin structure has been intensively modified, and played a great role in the oil and gas accumulation in the basin.
