摘　　要：西藏日土县埃永错地区发育自北向南的推覆构造,发育加木久-宋巴-狼当和种木干-祝若南4396高-沙尔多垄-狼当两条逆冲推覆断裂带,形成一系列构造窗和飞来峰构造。逆冲推覆构造形成于始新世之后,推覆体推覆距离大于3km。The from north to south nappe structures developed in the Aiyongcuo area of Ritu County,Tibet,comprise two overthrust nappe fault zones as the Jiamuiu-Songba-Langdang one and the Zhongmugan-Zhuruonan 4396m highland-Shaerduolong-Langdang one,forming a series of tectonic window and klippe structures.The overthrust structure was formed after the Eocene epoch and its nappes have overthrust distances of more than 3 km.
