Abstract: Taking the Late Jurassic shallow-water deltas developed in the foreland basin of western Sichuan area as cases and using integrated geological data of seismic profiles and well logs, the paper clarifies the sedimentary characteristics and its controls of the shallow-water deltas. The results show that the shallow-water delta systems in the foreland basin of western Sichuan are characterized by “coexistence of provenances along the long axis and short axis”, furthermore, during different depositional periods the supply capacity of the provenance were different along the long and short axises; the shallow-water deltas are mainly controlled by auto-cycle and allo-cycle, among which the control of episodic tectonic uplift on the shallow-water deltas is the main feature to distinguish depression basin and rifted basin. The study perfects the application of shallow-water delta theory in lacustrine basins and provides references for the studies on shallow-water delta developed in other foreland basins
