Any fault plane can be completely described with two measurements.
Normal fault hanging wall and footwall.
The hanging wall slides down relative to the footwall.
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.
An upthrown block between two normal faults dipping away from each other is a horst.
A downthrown block between two normal faults dipping towards each other is a graben.
Normal faults are common.
In some kinds of mineral deposits there is ore directly in the fault so.
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.
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.
True in a reverse fault the hanging wall block moves up relative to the footwall block.
Normal dip slip faults are produced by vertical compression as earth s crust lengthens.
Normal faults occur in areas undergoing extension stretching.
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.
In a normal fault the hanging wall moves downward relative to the footwall.
The hanging wall moves up relative to the foot wall.
The hanging wall moves down relative to the foot wall.
They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins.
The strike is the direction of the fault.
Low angle normal faults with regional tectonic significance may be designated detachment faults.
Generally speaking the hanging wall and footwall of a fault are in contact with each other.
When the fault plane is vertical there is no hanging wall or footwall.
Block position under the hanging wall.
Formed by tensional stress rocks are stretched away from each other reverse fault.
Its strike and its dip.
