Normal Fault Hanging Wall And Footwall

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.

Normal fault hanging wall and footwall.

Generally speaking the hanging wall and footwall of a fault are in contact with each other. Other articles where normal fault is discussed. Normal faults are common. The hanging wall slides down relative to the footwall.

True in a reverse fault the hanging wall block moves up relative to the footwall block. Any fault plane can be completely described with two measurements. Formed by compressional stress rocks are pushed towards each other thrust fault. Block position under the hanging wall.

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. An upthrown block between two normal faults dipping away from each other is a horst. The hanging wall moves down relative to the foot wall. Formed by tensional stress rocks are stretched away from each other reverse fault.

In some kinds of mineral deposits there is ore directly in the fault so. Low angle normal faults with regional tectonic significance may be designated detachment faults. The hanging wall moves up relative to the foot wall. Normal faults form in response to horizontal tensional stresses that stretch or elongate the rocks.

Also miners will mine ore not hanging walls or footwalls. 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. Normal dip slip faults are produced by vertical compression as earth s crust lengthens. When the fault plane is vertical there is no hanging wall or footwall.

If the hanging wall drops relative to the footwall you have a normal fault. In a normal fault the hanging wall moves downward relative to the footwall. The strike is the direction of the fault. Normal faults occur in areas undergoing extension stretching.
