An uplifted block between two normal faults that dip away from each other is called a horst. A horst forms as a result of the extensional movement on two parallel steeply dipping normal faults that dip away from each other. A horst can have a single bedding orientation or be bounded by several normal faults with multiple bedding attitudes, which are called terraced step faults. Horsts are structural geologic features. Block mountain landforms are usually made up of medium and large young horsts.
