用TL测年技术测定了沿小江断裂发育的主要河流低阶地沉积物的堆积年龄，结合毗邻地区同级阶地沉积物的堆积年代，估算了研究区低阶地面的形成时代，为建立研究区最新气候、构造事件的序列提供年代学依据。
Using TL dating technique to measure the accumulation ages of sediments in the lower reaches of major rivers along the Xiaojiang fault, the formation age of low-level ground in the study area was estimated based on the accumulation age of sediments of the same terraces in the adjacent area. In order to establish the latest research area, Climatic and tectonic events provide chronological evidence.
