Normal Fault Footwall Hanging Wall

The term footwall is derived from miners finding mineral deposits where inactive faults have been filled in with mineral deposits at their feet. Normal faults form in response to horizontal tensional stresses that stretch or elongate the rocks. Normal dip slip faults are produced by vertical compression as earth s crust lengthens.

Normal faults occur in areas undergoing extension stretching.

Normal fault footwall hanging wall.

Low angle normal fault footwall gneiss hanging wall shallow crust rocks. Hanging wall up footwall down. Low angle normal fault footwall gneiss hanging wall shallow crust rocks. They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins.

If the hanging wall drops relative to the footwall you have a normal fault. The dip of a reverse fault is relatively steep greater than 45. Basin and range region. Zones of crustal extension.

A reverse fault is the opposite of a normal fault the hanging wall moves up relative to the footwall. Hanging wall down footwall up. Other articles where normal fault is discussed. The fault plane is where the action is.

Hanging wall up footwall down. The hanging wall slides down relative to the footwall. The line it makes on the earth s surface is the fault trace. Where the fault plane is sloping as with normal and reverse faults.

Basin and range region. You can tell normal and reverse faults apart because at a normal fault the hanging wall has relative to the footwall. True in a reverse fault the hanging wall block moves up relative to the footwall block. Normal fault with the fault blocks on the right dropping downward myrna martin footwalls and hanging walls.

Dropped a fold is a in rock and a fault is a in rock. The terminology of normal and reverse comes from coal mining in england where normal faults are the most common. Zones of crustal extension. Edges of horsts and grabens.

The main components of a fault are 1 the fault plane 2 the fault trace 3 the hanging wall and 4 the footwall. Normal faults are common. Hanging wall down footwall up. Groups of normal faults can.

Normal fault geology a type of fault in which the hanging wall moves down relative to the footwall and the fault surface dips steeply commonly from 50o to 90o. Boundaries of metamorphic core complexes. Edges of horsts and grabens. Reverse faults indicate compressive shortening of the crust.

Footwall where miners find mineral deposits a normal fault will have a hanging wall and a footwall. It is a flat surface that may be vertical or sloping. Boundaries of metamorphic core complexes. If you imagine undoing the motion of a normal fault you will undo the stretching and thus shorten the horizontal distance between two points on either side of the fault.
