Boundaries of metamorphic core complexes.
Normal fault hanging wall.
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.
It is a flat surface that may be vertical or sloping.
This sliding downward of normal faults creates rifts valleys and mountains.
Hanging wall down footwall up.
If the hanging wall drops relative to the footwall you have a normal fault.
A n fault forms when the hanging wall moves down relative to the footwall a.
The fault plane is where the action is.
The hanging wall composed of extended thinned and brittle crustal material can be cut by numerous normal faults.
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.
The main components of a fault are 1 the fault plane 2 the fault trace 3 the hanging wall and 4 the footwall.
The line it makes on the earth s surface is the fault trace.
Hanging wall up footwall down.
Basin and range region.
A normal fault will have a hanging wall and a 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.
Normal dip slip faults are produced by vertical compression as earth s crust lengthens.
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.
Normal fault s are common.
As in experiments 1 and 2 antithetic faults are generally youngest near fault bends and oldest far from fault bends.
When the fault plane is vertical there is no hanging wall or footwall.
Zones of crustal extension.
Normal fractures in rock with no offset where there has been no motion are called.
The unloading of the footwall can lead to isostatic uplift and doming of the more ductile material beneath.
Edges of horsts and grabens.
The hanging wall slides down relative to the footwall.
Normal faults occur in areas undergoing extension stretching.
The term footwall is derived from miners finding mineral deposits where inactive faults have been filled in with mineral deposits at their feet.
Low angle normal fault footwall gneiss hanging wall shallow crust rocks.
The hanging wall is to the left of the fault and the footwall to the right.
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.
They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins.
