Fault-block mountains generally form by extension of the continental crust. The best examples include the Basin and Range Province of the western United States, and parts of the East African Rift System, including the Ethiopian Afar. These mountain belts are formed by the extension or pulling apart of the continental crust, forming basins between individual tilted fault-block mountains. These types of ranges are associated with thinning of the continental crust, and some have active volcanism as well as active extensional deformation.
