Fault-block mountains often result from rifting, an indicator of extensional tectonics. These can be small or form extensive rift valley systems, such as the East African Rift zone. Death Valley in California is a smaller example. There are two main types of block mountains; uplifted blocks between two faults and tilted blocks mainly controlled by one fault. WebUnlike typical (narrow) rifts, like the East African Rift, where the normal faulting due to tensional stresses related to rifting creates a central graben, wide rifts distribute the faulting over a series of horsts and grabens.
