摘要: 雅江断裂带①主要由4条断层组成3个向西南突出的巨大弧形断裂带。晚三叠世至第四纪,雅江断裂带都有沉积地层发育,从西北向东南,各弧形断裂带成为相继接受沉积的坳陷区,而同一时期,与之紧邻的南北两盘却为隆升区。雅江断裂带,正是在该区地壳多次层波运动中形成的。Abstract: The Yarlung Zangbo River fault zone cosists of four arcuate faults bending towards the southwest. The fault zones had become successively subsided from the northwest to the southeast to receive sediments from late Triassic up to the Quaternary,with the adjoining regions uplifted. The crustal movement that brought about the fault zone are characterized by an uplifting on the north and subsidence on the south of the region,the latter becoming subsequently elevated.
