Figure F4. A, B. East-west slices through the 3-D seismic volume. Overlays show seismic stratigraphic units. Color code and letters to identify seismic units are the same as in Figure F2, which shows correlation of seismic units with lithologic units and biostratigraphic ages. Important structural features are also labeled and identified as in Figure F2. The depth axis for A and B was derived from correlation with Site 1245. DBF = debris flow deposit. C, D. The depth axis on C and D was derived from Site 1251, Lines 300 and 343.
