Figure 7. Seismic facies of the upper slope and middle to lower slope environment. A. Line 107 is a strike line parallel to the platform margin at the upper slope. The fine-grained platform-derived slope deposits form a nearly transparent seismic facies. Channel incisions of as much as 150 m punctuate this facies. Major incisions appear at the early/late Pliocene boundary (e/f) and the Miocene/Pliocene boundary (f/g). B. Line 106 is a dip line across Site 1003, displaying the discontinuous seismic facies of the middle to lower slope as a result of a high variability in facies and small-scale channeling (modified from Anselmetti et al., in press).
