Normal Fault Hanging Wall

The unloading of the footwall can lead to isostatic uplift and doming of the more ductile material beneath.

Normal fault hanging wall.

Normal dip slip faults are produced by vertical compression as earth s crust lengthens. The fault plane is where the action is. The rift basin at the bottom of the north. 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.

As in experiments 1 and 2 antithetic faults are generally youngest near fault bends and oldest far from fault bends. The line it makes on the earth s surface is the fault trace. Normal faults occur in areas undergoing extension stretching. Boundaries of metamorphic core complexes.

Normal fault s are common. Edges of horsts and grabens. The hanging wall is to the left of the fault and the footwall to the right. Normal fractures in rock with no offset where there has been no motion are called.

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 is where the ore is eroding out of the rocks. 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. 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.

If the hanging wall drops relative to the footwall you have a normal fault. Hanging wall up footwall down. This sliding downward of normal faults creates rifts valleys and mountains. These either merge into the detachment fault at depth or simply terminate at the detachment fault surface without shallowing.

Basin and range region. The main components of a fault are 1 the fault plane 2 the fault trace 3 the hanging wall and 4 the footwall. Zones of crustal extension. A normal fault will have a hanging wall and a footwall.

The hanging wall slides down relative to the footwall. It is a flat surface that may be vertical or sloping. Low angle normal fault footwall gneiss hanging wall shallow crust rocks. 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.

When the fault plane is vertical there is no hanging wall or footwall. The hanging wall composed of extended thinned and brittle crustal material can be cut by numerous normal faults. They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins.
