Detailed explanation-1: -A dip-slip fault is a fault where one side is inclined above the higher due to vertical movement. A normal fault is one in which the footwall, or the side of rock above the inclined fault, moves upward. The other side of the rock is called the hanging wall and it moves downward in a normal fault.
Detailed explanation-2: -If the fault’s dip is inclined relative to the horizontal, the fault is a dip-slip fault (Figure below).
Detailed explanation-3: -A normal (dip-slip) fault is an inclined fracture where the rock mass above an inclined fault moves down.
Detailed explanation-4: -Faults which move along the direction of the dip plane are dip-slip faults and described as either normal or reverse (thrust), depending on their motion. Faults which move horizontally are known as strike-slip faults and are classified as either right-lateral or left-lateral.
Detailed explanation-5: -The general term of “dip-slip faults” is given to faults where there is vertical movement along the fault plane. Fault planes can become mineralized (form a channel for mineralizing fluids). Faults are classified according to their relative motion: Normal Fault: hanging wall has dropped relative to the footwall.
