Hanging Wall And Footwall Reverse Fault

The forces creating reverse faults are compressional pushing the sides together.

Hanging wall and footwall reverse fault.

Mike dunning dorling kindersle getty images. 2 1 volcanism is the process by which molten rock reaches the earth s surface in order to make new landforms. A reverse fault is the opposite of a normal fault the hanging wall moves up relative to the footwall. The dip of a reverse fault is relatively steep greater than 45.

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. These either merge into the detachment fault at depth or simply terminate at the detachment fault surface without shallowing. 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.

If the hanging wall rises relative to the footwall you have a reverse fault. This is the result of tension built up. 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 above is the hanging wall. Reverse faults are exactly the opposite of normal faults. This is a landform made from volcanism. Reverse faults indicate compressive shortening of the crust.

The hanging wall composed of extended thinned and brittle crustal material can be cut by numerous normal faults. The terminology of normal and reverse comes from coal mining in england where normal faults are the most common. Plutonism is the result of the magma as it has reached the earth s surface into pre existing rock. True the oldest sedimentary rock strata are exposed along the axial parts of deeply eroded anticlines.

They are common at convergent boundaries.
