Label Footwall Fault Hanging Wall

If the hanging wall moved up relative to the footwall the movement was caused by compression.

Label footwall fault hanging wall.

Most faults broken places are essentially inclined planes like this. Comments are turned off. 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.

Label the hanging wall block and the footwall block on each of the faults illustrated in figure 1. They are driven by significant tectonic events that affect large areas like continental collisions. That s the hanging wall. The line it makes on the earth s surface is the fault trace.

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. It is a flat surface that may be vertical or sloping. 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. A detachment fault is a particular kind of normal fault that generally dips at a low angle.

Compression pushing together causes reverse faults. Any fault plane can be completely described with two measurements. Click the buttons along the bottom of the image to see another example of interpreting a fault. Its strike and its dip.

Identify the type of fault illustrated by each photo and describe the type of stress that produced it. Quite often the ore that a miner wants to get to is sitting right on that inclined plane the ore is in the fault. 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. In a normal fault the hanging wall has moved down relative to 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. The keweenaw fault is a thrust fault the name we give to prominent reverse faults. Sketch label and describe the concepts of dip strike hanging wall and footwall. Draw a normal and reverse fault label the hanging wall and footwall for each also show how they move for each fault.

Tension stretching causes normal faults.
