Normal faults generally occur in places where the lithosphere is being stretched. They can also be found in deltas, at the rear edges of huge gravitation slumps and slides.
Normal faults can show diffeent geometries - and a few are shown here.
Other normal faults are found in batches, dipping in the same direction, with rotated fault blocks between. These are termed domino faults . Although most active normal faults can be shown to dip at angles steeper than 50 degrees, there are examples of very low-angle normal faults. Detachments show gentle dips and often expose high grade metamorphic rocks in their footwalls. These footwalls can be termed metamorphic core complexes.
