Abstract:The Longmenshan region inches the Longmenshan thrust belt,the western Sichuan fore-land basin , the Longquanshan tectonic belt, and the Minshan uplift. The NE-trending Long-menshan thrust belt is composed of 4 major thusts and related napes, which form an extensive-compressive belt. The thrusting, mainly in a forward propagation style, started in the middle tolater part of Late Triassic and propagated from northwest to southeast. The Quaternary activityof the central and southern parts of the Longmenshan belt is stronger than the northern part.The western Sichuan foreland basin began to develop in the Late Triassic. The basin graduallyretreated toward southwest since the late stage of Late Triassic, and the Quaternary deposition islimited on the Chengdu plain. The Longquanshan tectonic belt forms the eastern boundary of theforeland basin. It is a fault-propagation fold controlled by a master fault on its western margin.The NS-trending Minshan uplift northwest of the Longmenshan thrust
