Hanging Wall Block And Footwall Block

The block below is called the footwall.

Hanging wall block and footwall block.

Hangin wall moves down relative to the footwall. In diagram 111 below label the following. Hanging wall block b. Normal faults are caused by tensional stress.

In thrust faulting. Grabens are formed by what type of faulting. Hanging wall block and footwall block. What type of fault is illustrated.

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. What feature in distorted layered sedimentary rocks are evidence of horizontal compression and shortening. Sliding parallel to fault plane dip. The hanging wall block and footwall block are labeled in the following diagram.

Arrows indicating relative movement of fault blocks f. Normal fault as well. Strike of the fault plane d. Strike of the fault plane d.

The crust is shortened and thickened. When rocks slip past each other in faulting the upper or overlying block along the fault plane is called the hanging wall or headwall. This terminology comes from mining. When working a tabular ore body the miner stood with the footwall under his feet and with the hanging wall above him.

In a normal fault the hanging wall block moves down relative to the footwall block. Hanging wall and footwall the two sides of a non vertical fault are known as the hanging wall and footwall. Student name date lab section 9. Dipping fault the blocks are classified as vertical horizontal dipping dip slip strike slip oblique slip.

In a reverse fault the hanging wall block moves up relative to the footwall block. The hanging wall block above an inclined fault plane moves downward relative to the lower footwall block. Hanging wall block and footwall block remain in the same position vertically.
