Question

Briefly describe the relative movements and dominant stresses involved in the four major types of faults. Will mark best answer to who ever answers this correctly!

Answer 1

normal fault, reverse fault, Transcurrent Fault (Strike-Slip Fault), and Thrust Fault. 

Answer 2

In geology, a fault refers to a planar fracture of discontinuity in a volume of rock. Types of faults:

1. Based on the direction of slip the faults can be categorized as -

i. Strike-slip faults - The offset is predominantly horizontal and is parallel to the fault trace.

ii. Dip-slip faults - The offset is predominantly vertical and is perpendicular to the fault trace.

iii. Oblique-slip faults - Combines strike and dip slip.

2. Listric faults - The fault plane is curved, the dip is steeper near the surface and becomes shallow with increased depth.

3. Ring faults - They may be filled by ring dikes. They occur within collapsed volcanic calderas.

4. Synthetic and antithetic faults - They refer to minor faults associated with a major fault. Antithetic faults dip in the opposite direction of the major fault while synthetic faults dip in the same direction.
