Identify the type of fault illustrated by each photo and describe the type of stress that produced it.
Footwall block and hanging wall block.
The two sides of a non vertical fault are called the hanging wall and footwall.
Block below is called the footwall.
These names came from miners who excavated ore.
By definition the hanging wall occurs above the fault and the.
Label the hanging wall block and the footwall block on each of the faults illustrated in figure 1.
The footwall is the block that is below the fault.
Hanging wall block and footwall block the rock immediately above a fault surface is the hanging wall block and the one below is the footwall block.
A downthrown block between two normal faults dipping towards each other is a graben.
An upthrown block between two normal faults dipping away from each other is a horst.
On each photo draw arrows showing the relative movement on each side of the fault.
In a normal fault the hanging wall moves downward relative to the footwall.
The hanging wall is the fault block that is above the fault.
Low angle normal faults with regional tectonic significance may be designated detachment faults.
