Abstract

Abstract: The NS-trending Minshan mountain in Northwestern Sichuan is an active Quatemay uplift.Its western and eastern boundaries are controlled by the active Minshan and Huya faults, respectively. The northern segment of Minshan fault has been active since 2 Ma ago. It is a reverse fault with left－lateral strike-slip component. The strike-slip displacement is about 2.4 km with a 1mm/a slip rate since 2 Ma, determined by matching offset placer gold mine with its mother lode. The Minshan and Huya faults are the major seismogenic structures in the region.

Key words: Sichuan, Minshan uplift, Minjiang fault, Huya fault, Tectonic geomor phology

摘要： 岷山隆起为一第四纪强烈抬升区,构成川西高原的西界。岷山隆起的东、西边界分别受岷江断裂与虎牙断裂的控制,为地震活动带,南部向龙门山构造带过渡。岷江断裂北段的第四纪活动始于距今2Ma以前,为一逆走滑断层,观测到的左旋位移量为2.4km,左旋滑动速率为1mm/a.岷江断裂控制了沿隆起西界分布的地震活动,包括1933年叠溪和1960年漳腊地震。
