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