-
A.
Keystone Thrust Fault
The Keystone Thrust Fault is a prominent geological feature near Las Vegas where older limestone rock has been pushed up and over younger sandstone, creating dramatic cliffs and colorful rock formations visible in Red Rock Canyon.
-
B.
Caledonian fault system
The Caledonian fault system is a major ancient tectonic fracture network formed during the Caledonian orogeny that helped shape the geological structure of parts of Scotland and other regions in the North Atlantic.
-
C.
Marlborough Fault System
The Marlborough Fault System is a major network of active strike-slip faults in northeastern South Island, New Zealand, that transfers tectonic motion between the Alpine Fault and the Hikurangi subduction margin.
-
D.
Southern Uplands Fault
The Southern Uplands Fault is a major geological fault line in Scotland that marks the boundary between the Central Lowlands and the Southern Uplands, playing a key role in the region’s tectonic and landscape history.
-
E.
Imperial Fault Zone
The Imperial Fault Zone is a major active strike-slip fault system in Southern California that forms part of the southernmost extension of the San Andreas Fault system and is a significant source of regional earthquakes.
- F. None of above. chosen
