Hanging Wall Down Geology

Hanging wall and footwall.

Hanging wall down geology.

ø such a fault in which hanging wall has apparently moved down with respect to footwall is classified as a normal fault. When working a tabular ore body the miner stood with the footwall under his feet and with the hanging wall above him. The fault strike is the direction of the line of intersection between the fault plane and earth s surface. A fault in which hanging wall hw has apparently come down with respect to the footwall fw is termed as normal fault.

The two sides of a non vertical fault are known as the hanging wall and footwall. They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins of tectonic plates. This terminology comes from mining. Basin and range region.

The dip of a fault plane is its angle of inclination measured from the horizontal. Zones of crustal extension. Hanging wall up footwall down. A fault in which hanging wall has apparently gone up with respect to the footwall is termed as reverse fault.

ø in this definition it is clearly implied that nothing can be said with certainty whether it was the hanging wall which moved down or the foot wall which moved up or both the walls moved down the hanging wall moving more than the foot wall and hence the appearance. Normal faults are common. The block below is called the footwall. Low angle normal fault footwall gneiss hanging wall shallow crust rocks.

Rift valleys are formed by the sliding of the hanging walls downward many thousands of metres where they then become the valley floors. The hanging wall slides down relative to the footwall. Edges of horsts and grabens. The hanging wall occurs above the fault plane and the footwall occurs below it.
