Normal Fault 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 fault hanging wall.

Normal fractures in rock with no offset where there has been no motion are called. 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. The hanging wall slides down relative to the footwall. Edges of horsts and grabens.

If the hanging wall drops relative to the footwall you have a normal fault. The unloading of the footwall can lead to isostatic uplift and doming of the more ductile material beneath. Where the fault plane is sloping as with normal and reverse faults the upper side is the hanging wall and the lower side is the footwall. Hanging wall down footwall up.

Low angle normal fault footwall gneiss hanging wall shallow crust rocks. Normal fault s are common. Normal fault a type of fault in which the hanging wall moves down relative to the footwall and the fault surface dips steeply commonly from 50 o to 90 o. A n fault forms when the hanging wall moves down relative to the footwall a.

Hanging wall is where the ore is eroding out of the rocks. The main components of a fault are 1 the fault plane 2 the fault trace 3 the hanging wall and 4 the footwall. It is a flat surface that may be vertical or sloping. When the fault plane is vertical there is no hanging wall or footwall.

Groups of normal faults can produce horst and graben topography or a series of relatively high and low standing fault blocks as seen in areas where the crust is rifting or being pulled apart by plate tectonic activity. Hanging wall up footwall down. They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins. As in experiments 1 and 2 antithetic faults are generally youngest near fault bends and oldest far from fault bends.

Boundaries of metamorphic core complexes. The rift basin at the bottom of the north. These either merge into the detachment fault at depth or simply terminate at the detachment fault surface without shallowing. The fault plane is where the action is.

After 6 cm of displacement of the moveable wall the hanging wall deformation consists of a wide monocline cut by numerous antithetic and synthet ic normal faults figure 6d. Zones of crustal extension. A normal fault will have a hanging wall and a footwall. The hanging wall is to the left of the fault and the footwall to the right.

Normal faults occur in areas undergoing extension stretching. This sliding downward of normal faults creates rifts valleys and mountains. Basin and range region.
