Any fault plane can be completely described with two measurements.
Fault hanging wall footwall.
The unloading of the footwall can lead to isostatic uplift and doming of the more ductile material beneath.
Its strike and its dip.
The hanging wall composed of extended thinned and brittle crustal material can be cut by numerous normal faults.
The fault strike is the direction of the line of intersection between the fault plane and earth s surface.
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.
When the fault plane is vertical there is no hanging wall or footwall.
Draw a normal and reverse fault label the hanging wall and footwall for each also show how they move for each fault.
The dip of a fault plane is its angle of inclination measured from the horizontal.
The line it makes on the earth s surface is the fault trace.
Hanging wall and footwall the two sides of a non vertical fault are known as the hanging wall and footwall.
Also miners will mine ore not hanging walls or footwalls.
The hanging wall occurs above the fault plane and the footwall occurs below it.
Mainly because the names hanging wall and footwall were named by miners who weren t trying to be cute.
A n fault forms when the hanging wall moves down relative to the footwall a.
Normal fractures in rock with no offset where there has been no motion are called.
Quite often the ore that a miner wants to get to is sitting right on that inclined plane the ore is in the fault.
The dip of a fault plane is its angle of inclination measured from the horizontal.
Most faults broken places are essentially inclined planes like this.
The block below is called the footwall.
The fault strike is the direction of the line of intersection between the fault plane and earth s surface.
Generally speaking the hanging wall and footwall of a fault are in contact with each other.
When working a tabular ore body the miner stood with the footwall under his feet and with the hanging wall above him.
These either merge into the detachment fault at depth or simply terminate at the detachment fault surface without shallowing.
In fault fault plane is called the hanging wall or headwall.
It is a flat surface that may be vertical or sloping.
