Figure 10-Reconstruction (in sequence [animation]) of depth -converted seismic profile based in part on Figure 9. Pl. C, B, A = three sucessive Pliocene - Pleistocene levels (from oldest to youngest). Large extensions are balanced by reduction of shallow allochthonous salt body (green). Inverted triangles represent the approximate position of the paleoshelf margin based on paleontologic interpretation of depositional environments. The base of salt through time is based only on the structural relief above salt. Reconstruction by the PREP method.
