Label Footwall Fault Hanging Wall

A detachment fault is a particular kind of normal fault that generally dips at a low angle.

Label footwall fault hanging wall.

Comments are turned off. 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. Click the buttons along the bottom of the image to see another example of interpreting a fault. 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.

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. Draw a normal and reverse fault label the hanging wall and footwall for each also show how they move for each fault. It is a flat surface that may be vertical or sloping.

Sketch label and describe the concepts of dip strike hanging wall and footwall. The hanging wall moves up relative to the foot wall. Tension stretching causes normal faults. If the hanging wall moved up relative to the footwall the movement was caused by compression.

Mainly because the names hanging wall and footwall were named by miners who weren t trying to be cute. On each photo draw arrows showing the relative movement on each side of the fault. Most faults broken places are essentially inclined planes like this. 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.

Quite often the ore that a miner wants to get to is sitting right on that inclined plane the ore is in the fault. The line it makes on the earth s surface is the fault trace. They are driven by significant tectonic events that affect large areas like continental collisions. Its strike and its dip.

Compression pushing together causes reverse faults. 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. That s the hanging wall. The keweenaw fault is a thrust fault the name we give to prominent reverse faults.

In a normal fault the hanging wall has moved down relative to the footwall.
