断层 Fault (geology)

(重定向自Footwall)
一处断层

断层英语:fault)是指岩石破裂后,两侧岩石发生显着的相对位移。断层大小不等,大的断层可纵贯整个岩石圈,水平则可绵延几千公里。

由于地壳会在断层处作垂直或水平相互滑动,因此在断层处经常会发生地震。世界上最大的断层一般都是地球的板块边缘,但在远离活跃的板块边缘处人们也发现了许多大大小小的断层,例如中国就是板内断层十分发达的地区。由于较大的断层通常都不只是一个简单清晰的断面,而是一组断面的集合,因此人们又提出了断层带(或断层破碎带(英文)fault zone)的术语,在地质学文献中,规模巨大的断层带则通常叫做断裂带。

Microfault showing a piercing point (the coin's diameter is 18 mm)

In geology, a fault is a planar fracture or discontinuity in a volume of rock, across which there has been significant displacement as a result of rock mass movement. Large faults within the Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes.
