Abstract This paper, in terms of sequence stratigraphy and sedimentary dynamics, deals with sequence filling succession and sedimentary dynamic evolution of Xichang Compound Basin. The authors suggest that this basin possesses different tectonic nature during different geological evolution, and different genetic framework within different areas, revealing a typical composite characteristic of superposition in vertical and complex in horizontal. The sequence filling succession includes 2 supper-sequences, 5 mega sequences, 8 1st order sequences, 14 2nd order sequences, 76 3nd order sequences and lots of next hierarchy sequences, suggesting corresponding sea (lake) level changes with the same amount and cycles, respectively. Its formation and evolution are controlled by both tensile forces deduced from Tethyan plate and converging force from assembling among various plates. Its evolution underwent 3 stages, i e. fold base formation, passive marginal development and intracontinental reworking, includes orogenic rifting(Z1), passive continental margin(∈—P2), mantle budge and tension (P3), residual sea basin (T1—2), foreland basin(T3—J1), intracontinental depression, (J2—K1) and extrusion reworking (K2—E1) stages.
