Footwall Hanging Wall Reverse Fault

Reverse faults occur in areas undergoing compression squishing.

Footwall hanging wall reverse fault.

The hanging wall moves up relative to the foot wall. The hanging wall moves down relative to the foot wall. Reverse faults form when the hanging wall moves up. Faults showing vertical movement include tensional normal and compressional reverse faults.

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. A fault plane is a relatively flat surface where rocks break due to displacement. In a reverse fault the hanging wall right slides over the footwall left due to compressional forces.

In a strike slip fault they slide past each other the foot wall and hanging wall are not there because it has. The hanging wall slides down relative to the footwall. But that is when the foot wall moves down the hanging wall moves up. But that is when the foot wall moves down the hanging wall moves up.

In a strike slip fault they slide past each other the foot wall and hanging wall are not there because it has. Other articles where normal fault is discussed. If the hanging wall rises relative to the footwall you have a reverse fault. Footwall definition the top of the rock stratum underlying a vein or bed of ore.

Special type of reverse fault that is nearly horizontal angle has less than 45 degrees strike slip fault. Normal dip slip faults are produced by vertical compression as earth s crust lengthens. The dip of a reverse fault is relatively steep greater than 45. 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 forces creating reverse faults are compressional pushing the sides together. They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins. They are common at convergent boundaries. Reverse faults indicate compressive shortening of the crust.
