A fracture zone is a linear, oceanic feature characterized by a series of fractures and faults, often associated with transform faults that offset mid-ocean ridges. These zones are important in understanding the tectonic processes that shape the ocean floor, the movement of tectonic plates, and the distribution of earthquakes in the oceanic crust.
