9.Results and Conclusion  

The major results for scientific interest are concluded as follows:
1) A strong stuffing of the layers produces a relatively regular spacing of faults.
2) The mean fault interval seems to be positive correlation to the layer thickness.
3) Dip angles of faults are in good agreement with results of sand-box experiments 
                 anticipated from the Coulomb's Law of friction (Hubbert,1951).
4) As one fault stops dislocation movement the other starts at a far-side  position.  

Comparison with sand-box experiment:
Advantages:
1. The use of stundet friendly materials.
2. The structure shows more details because of finer grains (see SEM images).
Disadvantages:
1.This model is hard to simulate normal faults due to strong cohesion of flour. 
    However some prototypes solve partly this problem (see Examples part_2).
2.Strong cohesion sometimes prevents quantitative studies.

Conclusion for educational use:
Our model can easily simulate the fault mechanism in a class room.
Diversity of faults are so fascinating for students. 
Our model may easily extend for studying structural geology. 
And also we can study "mountain building" through this model. 
The model can help understanding the relation between earthquakes and faults. 
Students can understand the difficulty of earthquake prediction from the model.
