In order to know the relationship between the uplifting of Longmenshan Orogen and the filling characteristic of western Sichuan foreland-like basin during Late Triassic, this paper guided by sequence stratigraphy and sedimentology, integrated researched the outcrops, cores. The main achievements as follow were obtained: 1) from Late Triassic to Jurassic, the environment of western Sichuan foreland-like basin was different, the key stage was Anxian tectonic movement; 2) the tectonic movement of Longmenshan orogenisc belt was eposide, the movement of each part of Longmenshan orogenic belt was different form Late Triassic to Jurassic; and 3) during the Ma’antang Stage (TS1BE), tectonic movement of Longmenshan orogenisc belt was weak and entire underwater, mixed shelf is the mainly setting of the western Sichuan foreland basin and sponge reefs found in the Anxian district.
