Detailed explanation-1: -Reverse faults are exactly the opposite of normal faults. If the hanging wall rises relative to the footwall, you have a reverse fault. Reverse faults occur in areas undergoing compression (squishing).
Detailed explanation-2: -In reverse faults, the hanging wall moves upwards relative to the footwall. This motion can be determined by tracing the offset of the beds in a vertical motion in a block diagram. In map view, the hanging wall rocks will be older than the footwall rocks, due to erosion of the uplifted side (Figure 15).
Detailed explanation-3: -A normal fault is one in which the rocks above the fault plane, or hanging wall, move down relative to the rocks below the fault plane, or footwall. A reverse fault is one in which the hanging wall moves up relative to the footwall.
Detailed explanation-4: -If the hanging wall moves down relative to the foot wall, then it is a normal fault. b. If the foot wall moves down relative to the hanging wall, then it is a reverse fault. 2. When the motion on a fault is more horizontal, then it is called a strike-slip or lateral fault.
Detailed explanation-5: -Reverse Fault: In the field of geology, a reverse fault is a dip-slip fault in which the hanging wall moves upwards, relative to the footwall. The average dipping angle of a reverse fault ranges from 45 to 90 degrees.
