摘要
In order to know the coupling relationship between the Longmenshan orogen and the areas of West Sichuan, this paper studies the sequence-sedimentary filling characteristics of Upper Jurassic Penglaizhen Formation in the areas of West Sichuan by using sequence stratigraphy. It finds that the types of the sequence boundary are mainly the maximum flooding surface, the regional erosional unconformity surface, and the parallel unconformity surface and that five third-order sedimentary sequence are divided (SQ1～SQ5).
