Label Footwall Fault Hanging Wall

Any fault plane can be completely described with two measurements.

Label footwall fault hanging wall.

Sketch label and describe the concepts of dip strike hanging wall and footwall. Label the hanging wall block and the footwall block on each of the faults illustrated in figure 1. The line it makes on the earth s surface is the fault trace. Most faults broken places are essentially inclined planes like this.

In a normal fault the hanging wall has moved down relative to the footwall. A detachment fault is a particular kind of normal fault that generally dips at a low angle. That s the hanging wall. It separates rocks that were deep in the crust and ductile granite and gneiss from rocks of the upper crust sedimentary or volcanic that were brittle.

When the fault plane is vertical there is no hanging wall or footwall. Compression pushing together causes reverse faults. Be sure to include which type of stress creates each fault and the plate tectonic setting in which the fault is most likely to be found. The hanging wall moves up relative to the foot wall.

Quite often the ore that a miner wants to get to is sitting right on that inclined plane the ore is in the fault. Draw a normal and reverse fault label the hanging wall and footwall for each also show how they move for each fault. Mainly because the names hanging wall and footwall were named by miners who weren t trying to be cute. Use four block diagrams to depict and describe the movement of a normal fault reverse fault left lateral strike slip fault and right lateral strike slip fault.

Comments are turned off. On each photo draw arrows showing the relative movement on each side of the fault. It is a flat surface that may be vertical or sloping. Tension stretching causes normal faults.

They are driven by significant tectonic events that affect large areas like continental collisions. Its strike and its dip. Click the buttons along the bottom of the image to see another example of interpreting a fault. Formed by compressional stress rocks are pushed towards each other.

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.
