Faulting Hanging Wall Foot Wall

I know that for normal fault hanging wall goes down whereas a reverse fault hanging wall goes up.

Faulting hanging wall foot wall.

In normal faulting the hanging wall moves downwards in relation to 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. A dip slip fault in which the upper block above the fault plane moves up and over the lower block. Occurs when the hanging wall moves down relative to the foot wall reverse fault.

Encyclopaedia britannica universal images group getty images. A diagram outlining the basics of faulting. Dip slip movement occurs when the hanging wall moved predominantly up or down relative to the footwall. If the motion was down the fault is called a normal fault if the movement was up the.

When working a tabular ore body the miner stood with the footwall under his feet and with the hanging wall above him. Because the road lies on two pieces of rock it was broken once the strike slip faulting occurred. 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.

The hanging wall slides down relative to the footwall. Hanging wall and footwall. They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins. The two sides of a non vertical fault are known as the hanging wall and footwall.

This terminology comes from mining. I always get confused which side is hanging wall and foot wall. Compare the image to the right with the normal fault above. There is no hanging wall or foot wall in strike slip faulting.

If we hold the foot wall stationary gravity will normally want to pull the hanging wall down right. Hanging wall movement determines the geometric classification of faulting. Normal faults are common. Other articles where normal fault is discussed.

In reverse thrust faulting the hanging wall moves upward in relation to the footwall. Faults that move the way you would expect gravity to move them normally are called normal faults. Normal dip slip faults are produced by vertical compression as earth s crust lengthens.
