WebMultilayers of these same rocks fault rather than fold if contacts are bonded, but they fold readily if contacts between layers are frictionless, or have low yield strengths, for example due to high pore-water pressure. Faults may accompany the folds, occurring where compression is increased in cores of folds. WebMay 6, 2024 · Compression squeezes rocks together, causing rocks to fold or fracture (break) (figure 1).
