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