Hanging wall block and footwall block.

When rocks slip past each other in faulting the upper or overlying block along the fault plane is called the hanging wall or headwall. Hanging wall block b. The hanging wall block and footwall block are labeled in the following diagram. In diagram 111 below label the following.

Grabens are formed by what type of faulting. Sliding parallel to fault plane dip. The block below is called the footwall. 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. Strike of the fault plane d. Hanging wall definition the underside of the wall rock overlying a vein or bed of ore. When working a tabular ore body the miner stood with the footwall under his feet and with the hanging wall above him.

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. Hanging wall block and footwall block. The hanging wall occurs above the fault plane and the footwall occurs below it.

Hanging wall block and footwall block remain in the same position vertically. The crust is shortened and thickened. In thrust faulting. Hanging wall and footwall the two sides of a non vertical fault are known as the hanging wall and footwall.

In a n fault the hanging wall block moves up with the respect to the footwall block. What type of fault is illustrated. The hanging wall block above an inclined fault plane moves downward relative to the lower footwall block. In a normal fault the hanging wall block moves down relative to the footwall block.

Hangin wall moves down relative to the footwall. This terminology comes from mining. Strike of the fault plane d.
