Fault Hanging Wall Footwall

The fault strike is the direction of the line of intersection between the fault plane and earth s surface.

Fault hanging wall footwall.

It is a flat surface that may be vertical or sloping. A n fault forms when the hanging wall moves down relative to the footwall a. In some kinds of mineral deposits there is ore directly in the fault so you could say the miners were mining between the hanging wall and footwall. Also miners will mine ore not hanging walls or footwalls.

Block below is called the footwall. When the fault plane is vertical there is no hanging wall or footwall. Mainly because the names hanging wall and footwall were named by miners who weren t trying to be cute. Its strike and its dip.

The line it makes on the earth s surface is the fault trace. The block below is called the footwall. In fault fault plane is called the hanging wall or headwall. Hanging wall and footwall the two sides of a non vertical fault are known as the hanging wall and footwall.

These either merge into the detachment fault at depth or simply terminate at the detachment fault surface without shallowing. The unloading of the footwall can lead to isostatic uplift and doming of the more ductile material beneath. The hanging wall composed of extended thinned and brittle crustal material can be cut by numerous normal faults. When working a tabular ore body the miner stood with the footwall under his feet and with the hanging wall above him.

Quite often the ore that a miner wants to get to is sitting right on that inclined plane the ore is in the fault. Any fault plane can be completely described with two measurements. This terminology comes from mining. Normal fractures in rock with no offset where there has been no motion are called.

The hanging wall occurs above the fault plane and the footwall occurs below it. Most faults broken places are essentially inclined planes like this. The dip of a fault plane is its angle of inclination measured from the horizontal. Draw a normal and reverse fault label the hanging wall and footwall for each also show how they move for each fault.

Generally speaking the hanging wall and footwall of a fault are in contact with each other.
