Footwall Hanging Wall Reverse Fault

Formed by compressional stress rocks are pushed towards each other thrust fault.

Footwall hanging wall reverse fault.

Tensional faults are produced through tension extension or pulling apart of the crust causing the hanging wall to move down relative to the footwall. The hanging wall moves down relative to the foot wall. Other articles where normal fault is discussed. But that is when the foot wall moves down the hanging wall moves up.

If you imagine undoing the motion of a reverse fault you will undo the compression and thus lengthen the horizontal distance between two points on either side of the fault. But that is when the foot wall moves down the hanging wall moves up. A fault plane is a relatively flat surface where rocks break due to displacement. If the hanging wall rises relative to the footwall you have a reverse fault.

Normal faults are common. Faults showing vertical movement include tensional normal and compressional reverse faults. They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins. Reverse faults form when the hanging wall moves up.

The hanging wall moves up relative to the foot wall. Normal dip slip faults are produced by vertical compression as earth s crust lengthens. They are common at convergent boundaries. In a strike slip fault they slide past each other the foot wall and hanging wall are not there because it has.

In a reverse fault the hanging wall right slides over the footwall left due to compressional forces. The hanging wall slides down relative to the footwall. The dip of a reverse fault is relatively steep greater than 45. The forces creating reverse faults are compressional pushing the sides together.

Reverse faults occur in areas undergoing compression squishing. Footwall definition the top of the rock stratum underlying a vein or bed of ore. Reverse faults indicate compressive shortening of the crust. Mike dunning dorling kindersle getty images.
