Figure 3. Summary of lithologic columns for Sites 897 to 900 and a composite interpreted seismic section through these sites (see Fig. 1). Shading in the seismic section indicates the distribution of Pleistocene and Pliocene terrigenous turbidites and pelagics (Subunit IA) in the lithologic column (Sites 897 to 900) (modified after Sawyer, Whitmarsh, Klaus, et al., 1994).
