Hanging Wall And Footwall Reverse Fault

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.

Hanging wall and footwall reverse fault. In a reverse fault the hanging wall block moves up relative to the footwall block. The reverse faults occur when the hanging wall works its way up the footwall. In a reverse fault the hanging wall right slides over the footwall left due to compressional forces. The block below a fault plane is the footwall.

Reverse faults form when the hanging wall moves up. This is the result of tension built up. The terminology of normal and reverse comes from coal mining in england where normal faults are the most common. They are common at convergent boundaries.

Reverse faults indicate compressive shortening of the crust. Reverse faults occur in areas undergoing compression squishing. Mike dunning dorling kindersle getty images. Plutonism is the result of the magma as it has reached the earth s surface into pre existing rock.

The forces creating reverse faults are compressional pushing the sides together. The dip of a reverse fault is relatively steep greater than 45. These either merge into the detachment fault at depth or simply terminate at the detachment fault surface without shallowing. A reverse fault is the opposite of a normal fault the hanging wall moves up relative to the footwall.

The unloading of the footwall can lead to isostatic uplift and doming of the more ductile material beneath. 2 1 volcanism is the process by which molten rock reaches the earth s surface in order to make new landforms. The hanging wall composed of extended thinned and brittle crustal material can be cut by numerous normal faults. If the hanging wall rises relative to the footwall you have a reverse fault.

Reverse faults are exactly the opposite of normal faults.
