Label Footwall Fault Hanging Wall

Label footwall fault hanging wall.

Most faults broken places are essentially inclined planes like this. Quite often the ore that a miner wants to get to is sitting right on that inclined plane the ore is in the fault. Label the hanging wall block and the footwall block on each of the faults illustrated in figure 1. 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.

Draw a normal and reverse fault label the hanging wall and footwall for each also show how they move for each fault. In a normal fault the hanging wall has moved down relative to the footwall. Identify the type of fault illustrated by each photo and describe the type of stress that produced it. Formed by compressional stress rocks are pushed towards each other.

Mainly because the names hanging wall and footwall were named by miners who weren t trying to be cute. The keweenaw fault is a thrust fault the name we give to prominent reverse faults. Comments are turned off. A detachment fault is a particular kind of normal fault that generally dips at a low angle.

They are driven by significant tectonic events that affect large areas like continental collisions. Tension stretching causes normal faults. When the fault plane is vertical there is no hanging wall or footwall. That s the hanging wall.

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

Compression pushing together causes reverse faults. It is a flat surface that may be vertical or sloping. The hanging wall moves up relative to the foot wall. The line it makes on the earth s surface is the fault trace.

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.
