2.10 Basin and Range Province of Nevada, Fault Block Mountains: Plate Tectonics

Most mountain belts, including the Alps, Himalayas, and Appalachians, form in compressional environments, as evidenced by the predominance of large thrust faults and folded strata. However, other tectonic processes, such as continental rifting, also produce uplift and the formation of topographic mountains. The mountains that form in these settings, termed fault-block mountains, are bounded by high-angle normal faults that gradually flatten with depth. Most fault block mountains form in response to broad uplifting, which causes elongation and faulting. Such a situation is exemplified by the fault blocks that rise high above the rift valleys of East Africa.
