RAFT LINKAGE

This animation shows the progressive peeling of strata revealing subsurface 3-D structures in the model. Removing the upper two layers exposes the crests of the tallest diapirs (pale gray) and fault scarps seaward. Peeling another layer shows how rafts, which are separated in the dip section, connect between stocks rising from a salt wall; the rafts have been gently flexed to form turtle structures. Further peeling exposes deep levels where rafts are increasingly more isolated because of the greater extension of older strata. Completely exposed salt layer. Horizontal grooves (parallel to the red arrows) are the actual impressions of sand layers against the steeply dipping flanks of diapirs. These bedding traces illustrate the fidelity of the computer-rendered surfaces.
