断裂带是洋底最明显的构造。它们形成于大洋扩展中心出现错断的地方,留下了贯穿整个大洋盆地延伸几千公里的断崖。60年代和70年代,通过广泛的地磁和海深测量绘制了这些断裂带图,并常用于全球构造复原,但只是在最近5年左右,才集中研究断裂带本身的问题。

The fault zone is the most obvious structure of the ocean floor. They were formed at the wrong place of the Oceanic Expansion Center, leaving the cliffs extending thousands of kilometers across the entire oceanic basin. In the 1960s and 1970s, these fault zones were mapped using a wide range of geomagnetic and sea depth measurements and are commonly used for global structural restoration, but only focused on the fault zone itself in the last five years or so.
