The top model shows a post-tectonic drape sequence above a rigid basement high. The drape sequence thins toward the crest of the structure, with younger strata having less relief than older units. The lower model shows growth strata above a fold developed by progressive limb rotation. The two stratigraphic patterns are similar, and in some cases difficult to distinguish. Incorrect interpretations of drape and growth sequences can lead to flawed estimates of structural timing and kinematics. Thus, care should be taken in trying to distinguish between drape and growth sequences.
