- Picture 1Sediments are laid down horizontally.
- Picture 2Imagine the sediments are buried deep and are under pressure and subjected to higher temps. As stresses are imposed (from the right and left in this pic), the rock begins to deform.
- Picture 3Stresses continue to be applied over vast amounts of time, while the rock is still ductile. Eventually, the large fold at this site ended up looking very much like the fold in this picture.
