In the recent decade, the deep seismic reflection profiling has been applied widely to studies on formation and evolution of oceanic lithosphere, crust structures and so on.

近十年来，深地震反射波勘探在海洋岩石圈的形成与演化、地壳结构研究中的应用越来越广泛。

It is suggested therefore that the extensional direction evolution was controlled by the oceanic motion and the craton destruction took place under a back-arc spreading setting.

这反映华北克拉通东部区域拉伸方向的演变受控于太平洋区大洋板块运动，克拉通破坏的动力学背景应为弧后伸展。
