Abstract: Viewing from the global tectonics, the authors dynamically described the dialectical relationships between extensions and compressions in time special 4-D, and pointed out the different tectonic deformation systems corresponding to different tectonic dynamical environments. Considering the geological evolution of Sichuan Basin, from nine aspects, the authors proved that the tectonic dynamical environments of Sichuan Basin, after its formation, has experienced the early extension, middle transition and late compression environments. Correspondingly, as the paper suggests, a considerable attention need to be paid to the comprehensive studies of the early extensional structures, middle inversion structures and the late compression structures of Sichuan Basin when analyzing its tectonics.

Key words: Sichuan Basin, extension compression, dynamical environment, extensional structures, inversion structures
