Hanging Wall Normal Fault

The term footwall is derived from miners finding mineral deposits where inactive faults have been filled in with mineral deposits at their feet. In a normal fault the side that slides downward has a shape that makes it look like it is reaching or hanging out over the side so we call it the hanging wall. Normal faults occur in areas undergoing extension stretching.

Hanging wall deformation patterns differ signifi cantly when a basal plastic sheet imposes a con stant magnitude displacement distribution on the master normal fault.

Hanging wall normal fault.

Hanging wall is where the ore is eroding out of the rocks. Normal fault a type of fault in which the hanging wall moves down relative to the footwall and the fault surface dips steeply commonly from 50 o to 90 o. The hanging wall slides down relative to the footwall. Normal dip slip faults are produced by vertical compression as earth s crust lengthens.

A normal fault will have a hanging wall and a footwall. In models without a plastic sheet numerous secondary normal faults form in the hanging wall of the master normal fault. If you imagine undoing the motion of a normal fault you will undo the stretching and thus shorten the horizontal distance between two points on either side of the fault. The other side is shaped a little.

Normal fault s are common. If the hanging wall drops relative to the footwall you have a normal fault. They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins.
