Hanging wall movement determines the geometric classification of faulting.
How to determine hanging wall and footwall on map.
In a fault plane that dips 45 degrees the overlying rock unit is the hanging wall and the underlying rock unit is the footwall.
The fault plane is where the action is.
This situation however is generally found only in cirques cut into flat plateaus.
The line it makes on the earth s surface is the fault trace.
An arcuate cliff called the headwall.
If the hanging wall drops relative to the footwall you have a normal fault.
When working a tabular ore body the miner stood with the footwall under his feet and with the hanging wall above him.
This terminology comes from mining.
It is a flat surface that may be vertical or sloping.
In an ideal cirque the headwall is semicircular in plan view.
We distinguish between dip slip and strike slip hanging wall movements.
Dip slip movement occurs when the hanging wall moved predominantly up or down relative to the footwall.
Hanging wall and footwall.
The hanging wall occurs above the fault plane and the footwall occurs below it.
The main components of a fault are 1 the fault plane 2 the fault trace 3 the hanging wall and 4 the footwall.
Draw a normal and reverse fault label the hanging wall and footwall for each also show how they move for each fault.
The fault strike is the direction of the line of intersection between the fault plane and earth s surface.
More common are headwalls angular in map view due to irregularities in height along.
Strike slip faults are vertical and thus do not have hanging walls or footwalls.
The block below your feet is the footwall and the one upon which you would hang your miner s lamp is the hanging wall.
The two sides of a non vertical fault are known as the hanging wall and footwall.
In normal faulting the hanging wall moves downwards in relation to 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.
It is that simple.
The hanging wall is above the footwall.
Cirques tarns u shaped valleys arêtes and horns.
