Hanging Wall Block And Footwall Block

Hanging wall and footwall the two sides of a non vertical fault are known as the hanging wall and footwall.

Hanging wall block and footwall block.

This terminology comes from mining. Normal fault as well. In a n fault the hanging wall block moves up with the respect to the footwall block. Strike of the fault plane d.

Strike of the fault plane d. Arrows indicating relative movement of fault blocks f. When working a tabular ore body the miner stood with the footwall under his feet and with the hanging wall above him. The block below is called the footwall.

Hanging wall definition the underside of the wall rock overlying a vein or bed of ore. When rocks slip past each other in faulting the upper or overlying block along the fault plane is called the hanging wall or headwall. In diagram 111 below label the following. The hanging wall block above an inclined fault plane moves downward relative to the lower footwall block.

Although the angle of inclination of a specific fault plane tends to be relatively uniform it may differ considerably along its length from place to place. Sliding parallel to fault plane dip. Hanging wall block and footwall block remain in the same position vertically. Student name date lab section 9.

Hanging wall block and footwall block. Hangin wall moves down relative to the footwall. The crust is shortened and thickened. Normal faults are caused by tensional stress.

In a reverse fault the hanging wall block moves up relative to the footwall block. What feature in distorted layered sedimentary rocks are evidence of horizontal compression and shortening. The hanging wall block and footwall block are labeled in the following diagram. In thrust faulting.

Hanging wall block b. In a normal fault the hanging wall block moves down relative to the footwall block. Grabens are formed by what type of faulting.
