This model was developed in order to study the rotation of footwall rocks beneath oceanic detachment faults (ODFs). It showed that solid-block rotation dominates beneath a concave-down fault, while significant flexural stresses form later during "apparent unbending," causing both compression and extension-related brittle strain within oceanic core complexes (OCCs).
