Hanging Wall And Footwall Reverse Fault

This is a landform made from volcanism.

Hanging wall and footwall reverse fault.

A reverse fault is the opposite of a normal fault the hanging wall moves up relative to the footwall. Plutonism is the result of the magma as it has reached the earth s surface into pre existing rock. The block below a fault plane is the footwall. These either merge into the detachment fault at depth or simply terminate at the detachment fault surface without shallowing.

This is the result of tension built up. Reverse faults are exactly the opposite of normal 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.

Reverse faults occur in areas undergoing compression squishing. The forces creating reverse faults are compressional pushing the sides together. If the hanging wall rises relative to the footwall you have a reverse fault. In a reverse fault the hanging wall right slides over the footwall left due to compressional forces.

The reverse faults occur when the hanging wall works its way up the footwall. The block above is the hanging wall. The terminology of normal and reverse comes from coal mining in england where normal faults are the most common. 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. True the oldest sedimentary rock strata are exposed along the axial parts of deeply eroded anticlines. Reverse faults indicate compressive shortening of the crust. The dip of a reverse fault is relatively steep greater than 45.

In a reverse fault the hanging wall block moves up relative to the footwall block.
