    运用探槽开挖,揭露还原构造运动的方法,对沿塔尔湾断裂分布的地貌陡坎的形成过程进行了分析,得出了塔尔湾断裂的主要活动时期为早中更新世,现在地貌上的陡坎是外动力作用形成的,不是断裂活动形成的结论。

    By means of excavating the trial trench and exposing the tectonic movements,the forming process of the surface scarps has been analyzed,which are distributed along Tarwan fault.The results have showed that the main active period of Tarwan fault is early-mid Pleistocene.And the scarps in nowadays physiognomy were formed by outer dynamic,not the fault activities.
