野外调查表明 ,西藏东南部的嘉黎断裂带从那曲到嘉黎由三段呈雁行排列 ,大致沿N60°W方向延伸 ,其东南段在波密附近向南转折 ,沿贡日嘎布曲向南南东过上察隅和下察隅后转为近南北向延入缅甸境内与什阶断裂相连。嘉黎断层全新世以来活动性不强 ,其第四纪以来的平均滑动速率约为 4mm/a。一个有趣的现象是 ,虽然总体上嘉黎断裂的新活动不强 ,但在局部与张性盆地相邻的地段表现出较强的活动性 ,在这些段上沿断裂发育晚第四纪地表破裂 ,横跨断层的冲沟和河流被错断 ,其晚第四纪以来的平均滑动速率达到 15mm/a。但是这种现象的存在只局限在盆地中 ,盆地以外则截然终止 ,不复存在。从上述事实看 ,嘉黎断裂的走滑活动似乎是伴随张性活动而产生的 ,在断层几何和活动特征上类似于横切大洋中脊的转换断层。
Field surveys show that the Jiali fault zone in southeastern Tibet is arranged from three sections to the Jili section from Nagqu to Jiali and extends roughly along the direction of N60 ° W. Its southeast section turns southwards near Bomi, South and East after the Chayou and Chai Yu under the transition to nearly north-south extension into Burma and the Stratum fault. The activity of Jiali fault since the Holocene is not strong. The average slip rate since Quaternary was about 4mm / a. It is interesting to note that although the new activities of the Jiali fault in general are not strong, the areas adjacent to the Zhang-Zhang basin show strong activity, and the Quaternary surface ruptures along the faults during these periods , The gully and river across the fault were disrupted and its average slip rate since late Quaternary reached 15 mm / a. However, the existence of this phenomenon is confined to the basin, while the termination of the basin is completely absent. From the above facts, it seems that the strike-slip activities of the Jiali fault originated with the activity of tension and resemble the transection faults transecting the mid-ocean ridge in terms of fault geometry and activity.
