This terminology comes from mining.
How to identify hanging wall and footwall.
The hanging wall is above the footwall.
In a strike slip fault they slide past each other the foot wall and hanging wall are not there because it has.
To determine which is which visualize yourself creating a mine in along the fault.
It is a flat surface that may be vertical or sloping.
Hanging wall movement determines the geometric classification of faulting.
Then you determine the relative motion between the hanging wall and footwall.
In normal faulting the hanging wall moves downwards in relation to the footwall.
An arcuate cliff called the headwall.
Dip slip movement occurs when the hanging wall moved predominantly up or down relative to the footwall.
Other articles where normal fault is discussed.
The fault plane is where the action is.
In an ideal cirque the headwall is semicircular in plan view.
We distinguish between dip slip and strike slip hanging wall movements.
The two sides of a non vertical fault are known as the hanging wall and footwall.
This situation however is generally found only in cirques cut into flat plateaus.
The hanging wall slides down relative 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.
The hanging wall occurs above the fault plane and the footwall occurs below it.
The line it makes on the earth s surface is the fault trace.
Draw a normal and reverse fault label the hanging wall and footwall for each also show how they move for each fault.
Hanging wall and footwall.
But that is when the foot wall moves down the hanging wall moves up.
When working a tabular ore body the miner stood with the footwall under his feet and with the hanging wall above him.
To correctly identify a fault you must first figure out which block is the footwall and which is the hanging wall.
More common are headwalls angular in map view due to irregularities in height along.
Cirques tarns u shaped valleys arêtes and horns.
Normal dip slip faults are produced by vertical compression as earth s crust lengthens.
If the motion was down the fault is called a normal fault if the movement was up the.
They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins.
The main components of a fault are 1 the fault plane 2 the fault trace 3 the hanging wall and 4 the footwall.
