Hanging Wall Block And Footwall Block

The block below is called the footwall.

Hanging wall block and footwall block.

When working a tabular ore body the miner stood with the footwall under his feet and with the hanging wall above him. In a n fault the hanging wall block moves up with the respect to the 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. This terminology comes from mining.

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. Normal faults are caused by tensional stress. The hanging wall block above an inclined fault plane moves downward relative to the lower footwall block.

Hangin wall moves down relative to the footwall. Student name date lab section 9. Arrows indicating relative movement of fault blocks f. 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. Dipping fault the blocks are classified as vertical horizontal dipping dip slip strike slip oblique slip. Strike of the fault plane d. Hanging wall block and footwall block.

Hanging wall block b. The hanging wall occurs above the fault plane and the footwall occurs below it. Normal fault as well. In thrust faulting.

In a reverse fault the hanging wall block moves up relative to the footwall block. In diagram 111 below label the following. The crust is shortened and thickened. Strike of the fault plane d.

What type of fault is illustrated. 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 remain in the same position vertically.
