Faulting Hanging Wall Foot Wall

The hanging wall slides down relative to the footwall.

Faulting hanging wall foot wall.

This terminology comes from mining. Dip slip movement occurs when the hanging wall moved predominantly up or down relative to the footwall. Compare the image to the right with the normal fault above. Normal dip slip faults are produced by vertical compression as earth s crust lengthens.

In normal faulting the hanging wall moves downwards in relation to the footwall. Occurs when the hanging wall moves down relative to the foot wall reverse fault. In reverse thrust faulting the hanging wall moves upward in relation to the footwall. I know that for normal fault hanging wall goes down whereas a reverse fault hanging wall goes up.

If the motion was down the fault is called a normal fault if the movement was up the. They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins. There is no hanging wall or foot wall in strike slip faulting. I always get confused which side is hanging wall and foot wall.

Encyclopaedia britannica universal images group getty images. The main components of a fault are 1 the fault plane 2 the fault trace 3 the hanging wall and 4 the footwall. In the first picture we can see that strike slip faulting has occurred because there is no hanging wall or foot wall the layers of rock still line up and the road no longer lines up. Other articles where normal fault is discussed.

A dip slip fault in which the upper block above the fault plane moves up and over the lower block. Hanging wall movement determines the geometric classification of faulting. When working a tabular ore body the miner stood with the footwall under his feet and with the hanging wall above him. Normal faults are common.

The two sides of a non vertical fault are known as the hanging wall and footwall. The hanging wall occurs above the fault plane and the footwall occurs below it. If we hold the foot wall stationary gravity will normally want to pull the hanging wall down right. We distinguish between dip slip and strike slip hanging wall movements.

This type of faulting is common in areas of compression when the dip angle is shallow a reverse fault is often described as a thrust fault. Faults that move the way you would expect gravity to move them normally are called normal faults. Draw a normal and reverse fault label the hanging wall and footwall for each also show how they move for each fault.
