Thrust fault: these are variety of reverse faults in which the hanging wall has moved up with respect to footwall and the fault dip at the angle below 45 degrees.Ĭ.Reverse faults: this type of fault in which the hanging wall appears to have moved up with respect to the foot wall and dips at the angle more than 45 degrees. Graben: when two normal faults are on the either side of a wedge shaped block such that it appears downwards with respect to either blocks.ī.Horst : when two normal faults are on the either side of a central wedge shaped block such that it appears high up with respect to either blocks. Normal faults: faults in which the hanging wall is moved down with respect to the foot wall. Following are the factors commonly considered important :ġ.The apparent movement of the rock blocks along the fault plane.ģ.The relation of the fault altitude with the altitude of the displaced bedĪ.

Throw: The vertical component measured in vertical plane containing the dip. There are strike separation, dip separation, and net separation.ġ.Heave: The horizontal component of dip separation measured perpendicular to strike of the fault.Ģ.

Separation: The amount of apparent offset of a faulted surface, measured in specified direction.

it is combination of strike and dip direction.

Slip and separation: slip may be defined as the relative motion of rock blocks along fault planes.ġ.Strike slip: the slip that occurs along the direction of the strike of fault plane.Ģ.Dip slip : the slip that occurs along the direction of the dip of the fault plane.ģ.Oblique slip: the slip that occurs both in dip and strike direction i.e.

Fault plane: it is the planer surface along which relative displacement of blocks takes place during the process of faulting.ġ.Hanging wall: it is the term used for the faulted block which lies on the upper surface of the fault plane.Ģ.Foot wall: it is the term used for the faulted block which lies on the under surface of the fault plane.

It may be defined as a fracture surface in rock across which there is relative motion parallel to the surface between the adjacent blocks of the rock.
