Aulacogen

An aulacogen is a failed arm of a triple junction.^[1] Aulacogens are a part of plate tectonics where oceanic and continental crust is continuously being created, destroyed, and rearranged on the Earth’s surface. Rift zones are places where new crust is formed. An aulacogen is a rift zone that is no longer active.^[2]
