| 摘 要： | 甘孜-理塘断裂带是义敦造山带与雅江褶皱带的分界断裂。该带由韧性又脆性冲断层、平移断层,以及各种岩块、构造岩片等组合而成。其演化历史主要经历了晚三叠世洋壳的俯冲、晚三叠世末期弧-陆碰撞、陆内会聚和喜马拉雅期断陷的复杂演化过程。

| Abstract: | Garze-Litang fracture zone separates Yidun orogenic belt from Yajiang folded belt. The said frac-ture zone is composed of a series of ductile and brittle thrust faults,strike-slip faults and blocks as well as tectonic slices. It has undergone a complicated evolutionary process from ocean plate subduction in Late Triassic, island arc-continental plate collision and intracontinental plate convergence at the end of Late Triassic to rift faulting in Himalayan epoch. |
