Hanging Wall Down Geology

They bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins of tectonic plates.

Hanging wall down geology.

Hanging wall and footwall. Fault plane is called the hanging wall or headwall. The block below is called the footwall. The fault strike is the direction of the line of intersection between the fault plane and earth s surface.

Edges of horsts and grabens. ø such a fault in which hanging wall has apparently moved down with respect to footwall is classified as a normal fault. The two sides of a non vertical fault are known as the hanging wall and footwall. Rift valleys are formed by the sliding of the hanging walls downward many thousands of metres where they then become the valley floors.

The dip of a fault plane is its angle of inclination measured from the horizontal. This terminology comes from mining. The hanging wall occurs above the fault plane and the footwall occurs below it. 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. A fault in which hanging wall hw has apparently come down with respect to the footwall fw is termed as normal fault. Boundaries of metamorphic core complexes. Hanging wall up footwall down.

Normal faults are common. Hanging wall down footwall up. Basin and range region. 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.
