How To Identify Hanging Wall And Footwall

Dip slip movement occurs when the hanging wall moved predominantly up or down relative to the footwall.

How to identify hanging wall and footwall.

We distinguish between dip slip and strike slip hanging wall movements. Normal dip slip faults are produced by vertical compression as earth s crust lengthens. An arcuate cliff called the headwall. In normal faulting the hanging wall moves downwards in relation to the footwall.

Normal faults are common. Every fault tilted from the vertical has a hanging wall and footwall. More common are headwalls angular in map view due to irregularities in height along. This terminology comes from mining.

In a strike slip fault they slide past each other the foot wall and hanging wall are not there because it has. They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins. To determine which is which visualize yourself creating a mine in along the fault. The hanging wall is above the footwall.

The main components of a fault are 1 the fault plane 2 the fault trace 3 the hanging wall and 4 the footwall. Draw a normal and reverse fault label the hanging wall and footwall for each also show how they move for each fault. Hanging wall and footwall. It is a flat surface that may be vertical or sloping.

To correctly identify a fault you must first figure out which block is the footwall and which is the hanging wall. The two sides of a non vertical fault are known as the hanging wall and footwall. But that is when the foot wall moves down the hanging wall moves up. The hanging wall occurs above the fault plane and the footwall occurs below it.

The line it makes on the earth s surface is the fault trace. This situation however is generally found only in cirques cut into flat plateaus. If the motion was down the fault is called a normal fault if the movement was up the. Then you determine the relative motion between the hanging wall and footwall.

The hanging wall slides down relative to the footwall. When working a tabular ore body the miner stood with the footwall under his feet and with the hanging wall above him. Cirques tarns u shaped valleys arêtes and horns. Other articles where hanging wall is discussed.

Hanging wall movement determines the geometric classification of faulting. Other articles where normal fault is discussed.
