2. What is a Fault?
 Faults are fractures along which movement of
one block with respect to others has taken
place.
 This movement may vary from a few centimeters
to many kilometers depending on stresses and
resistance offered by the rocks.

3. Parts of a Fault

4. Classification of Faults:
Normal Fault
 A fault in which hanging wall has apparently come down with
respect to the foot wall is termed a Normal Fault.

5. Reverse Fault
 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.

6. Thrust Fault
 This is a type 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

7. Vertical Fault
 A fault in which the fault plane is vertical and either of the walls has
moved upwards or downwards.

8. Horst Fault
 Horst (German = up throw) fault is one in which wedge shaped
block has gone up with respect to the side blocks.

9. Graben Fault/Trench fault
 Graben (German=trench) Fault is one in which wedge shaped
block has come down with respect to side block.

10. Dip Fault
 A Dip fault is a type of fault in which the stike is parallel to the dip of
strata.

11. Strike Fault
 A strike fault is the one whose strike is parallel to the strike of the
strata.

12. Parallel Faults
 A series of faults running more or less parallel to one another and
hading in the same direction.

13. Step Fault
 Step fault is a type of parallel fault where down throw is all in the
same direction a it gives a step like arrangement.
