Footwall And Hanging Wall Normal Fault

Any fault plane can be completely described with two measurements.

Footwall and hanging wall normal fault. When the fault plane is vertical there is no hanging wall or footwall. Hanging wall up footwall down. 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.

Its strike and its dip. Formed by compressional stress rocks are pushed towards each other thrust fault. Hanging wall down footwall up. In a normal fault the hanging wall moves downward relative to the footwall.

Basin and range region. Low angle normal fault footwall gneiss hanging wall shallow crust rocks. There is a normal fault which happens at a divergent boundary. Normal dip slip faults are produced by vertical compression as earth s crust lengthens.

It is caused by tension. Normal fault with the fault blocks on the right dropping downward myrna martin footwalls and hanging walls. The hanging wall moves up relative to the foot 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 occur in areas undergoing extension stretching. A downthrown block between two normal faults dipping towards each other is a graben. An upthrown block between two normal faults dipping away from each other is a horst. Zones of crustal extension.

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 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. Boundaries of metamorphic core complexes. They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins. 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.

Block position under the hanging wall. Edges of horsts and grabens. Low angle normal faults with regional tectonic significance may be designated detachment faults. Footwall where miners find mineral deposits a normal fault will have a hanging wall and a footwall.

Other articles where normal fault is discussed. If the hanging wall drops relative to the footwall you have a normal fault. The strike is the direction of the fault. The hanging wall moves down relative to the foot wall.

In this fault the hanging wall moves down relative to the footwall.
