i)- Crustal rock layers are subjected to compressional forces
- This leads to formation of a massive article /up fold
- Further compression to the same crustal rocks causes stress/tension at the crest of the anticline
- Eventually a crack/fault and around the crust of the anticline called an anticline fault

ii) - Crustal rock layers are subjected to compressional forces
- Intense folding results into formation of an overfold
- With increased pressure the over fold is compressed further to form a recumbent fold
- When pressure if very great, a fracture occurs along the axis producing a thrust plane
to form an overthrust fold
