What are the 4 different types of faults?

Answer 1

The 4 main types of fault are summarised below:

• Dip-slip faults
• Strike-slip / transcurrent faults
• Oblique-slip faults
• Listric fault

Dip slip faults are those where the relative motion on the fault is broadly vertical. Examples include normal faults where the hanging wall moves down relative to the foot wall. Reverse faults have the opposite sense of motion, with the hangingwall moving up relative to the footwall. Thrust faults are a special type of reverse fault where the dip of the fault plane is at a shallower angle than 45 degrees from the horizontal.

Strike slip or transcurrent faults are those where the relative motion on the fault is broadly horizontal. The fault plane in these types of faults is normally near vertical and the sense of motion is described in terms of the relative movement of the rockmass on the far side of the fault plane. If this relative movement is to the left, then it is known as a sinistral fault. If he motion is to the right it is a dextral fault.

Oblique slip faults are those have have a significant component of both vertical and horizontal movement. They can be thought of a composite of the dip slip and strike slip faults.

Listric faults are characterised by a curved fault plane surface. They usually start of relatively steep and then become more shallow with increased depth and may ultimately become horizontal.

Previous Answer:

The four different types of faults are normal, reverse, transcurrent (also known as strike-slip), and thrust. Normal faults are so named because movement follows what would be expected from normal effects of gravity--one plate slides downward, pulled by gravity, and the other plate forms a cliff face. The reverse fault, then, is the opposite of a normal fault--one plate moves against gravity and slides over the other. Transcurrent faults feature horizontal movement rather than up/down movement; plates slide along each other, resulting in offset roads and such. Finally, thrust faults are similar to reverse faults--one plate moves over the other--but the angles of movement for thrust faults are generally less steep, and thrust faults are more commonly associated with geographical features such as mountain ranges.

Answer 2

only 1. fault plane- surface of a fault along which movement of rocks occurs.

2. thrust fault type of reverse fault- in which the fault plane is nearly horisontal rather than vertical.

3.strike slip fault- fault in which the rock on either saide of a fault olane slides horizontally

4.normal fault- fault i which the hanging wall moves down realtive tothe footwall.

Answer 3

the three types of faults are normal (colliding), reverse (moving apart), strike-slip (sliding past each other)

Answer 4

There are only 3 basic types of fault, not 4.

1. thrust faults
2. normal Faults
3. transverse faults.
