Label Footwall Fault Hanging Wall

Identify the type of fault illustrated by each photo and describe the type of stress that produced it.

Label footwall fault hanging wall. Formed by compressional stress rocks are pushed towards each other. They are driven by significant tectonic events that affect large areas like continental collisions. It is a flat surface that may be vertical or sloping. A detachment fault is a particular kind of normal fault that generally dips at a low angle.

Compression pushing together causes reverse faults. The hanging wall moves up relative to the foot wall. Tension stretching causes normal faults. Quite often the ore that a miner wants to get to is sitting right on that inclined plane the ore is in the fault.

Comments are turned off. Mainly because the names hanging wall and footwall were named by miners who weren t trying to be cute. 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. Any fault plane can be completely described with two measurements.

Draw a normal and reverse fault label the hanging wall and footwall for each also show how they move for each fault. On each photo draw arrows showing the relative movement on each side of the fault. If the hanging wall moved up relative to the footwall the movement was caused by compression. Label the hanging wall block and the footwall block on each of the faults illustrated in figure 1.

In a normal fault the hanging wall has moved down relative to the footwall. When the fault plane is vertical there is no hanging wall or footwall. Most faults broken places are essentially inclined planes like this. Its strike and its dip.

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. 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. 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. That s the hanging wall.

Sketch label and describe the concepts of dip strike hanging wall and footwall.
