Hanging Wall And Footwall Reverse Fault

Reverse faults occur in areas undergoing compression squishing.

Hanging wall and footwall reverse fault.

The block below a fault plane is the footwall. The forces creating reverse faults are compressional pushing the sides together. The dip of a reverse fault is relatively steep greater than 45. The block above is the hanging wall.

Reverse faults form when 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. The reverse faults occur when the hanging wall works its way up the footwall. Reverse faults indicate compressive shortening of the crust.

The unloading of the footwall can lead to isostatic uplift and doming of the more ductile material beneath. In a reverse fault the hanging wall block moves up relative to the footwall block. 2 1 volcanism is the process by which molten rock reaches the earth s surface in order to make new landforms. Plutonism is the result of the magma as it has reached the earth s surface into pre existing rock.

A reverse fault is the opposite of a normal fault the hanging wall moves up relative to the footwall. This is a landform made from volcanism. These either merge into the detachment fault at depth or simply terminate at the detachment fault surface without shallowing. If the hanging wall rises relative to the footwall you have a reverse fault.

True the oldest sedimentary rock strata are exposed along the axial parts of deeply eroded anticlines.
