Normal fault footwall hanging wall.

Where the fault plane is sloping as with normal and reverse faults. Hanging wall down footwall up. Dropped a fold is a in rock and a fault is a in rock. Normal fault with the fault blocks on the right dropping downward myrna martin footwalls and hanging walls.

You can tell normal and reverse faults apart because at a normal fault the hanging wall has relative to the footwall. The dip of a reverse fault is relatively steep greater than 45. Low angle normal fault footwall gneiss hanging wall shallow crust rocks. A reverse fault is the opposite of a normal fault the hanging wall moves up relative to the footwall.

The line it makes on the earth s surface is the fault trace. Normal faults occur in areas undergoing extension stretching. It is a flat surface that may be vertical or sloping. Hanging wall down footwall up.

Zones of crustal extension. Zones of crustal extension. The main components of a fault are 1 the fault plane 2 the fault trace 3 the hanging wall and 4 the footwall. If the hanging wall drops relative to the footwall you have a normal fault.

Groups of normal faults can. Normal faults form in response to horizontal tensional stresses that stretch or elongate the rocks. 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. Boundaries of metamorphic core complexes.

Edges of horsts and grabens. Hanging wall up footwall down. Normal faults are common. Hanging wall up footwall down.

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. Normal dip slip faults are produced by vertical compression as earth s crust lengthens. They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins.

Low angle normal fault footwall gneiss hanging wall shallow crust rocks. The hanging wall slides down relative to the footwall. The term footwall is derived from miners finding mineral deposits where inactive faults have been filled in with mineral deposits at their feet. True in a reverse fault the hanging wall block moves up relative to the footwall block.

The terminology of normal and reverse comes from coal mining in england where normal faults are the most common. 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. Basin and range region. The fault plane is where the action is.
