Figure 4. Stratigraphic correlation chart for the Leg 149 sites. Depositional hiatuses are defined by biostratigraphic data (see Sawyer, Whitmarsh, Klaus, et al.  for further information). Contourites were differentiated from turbidites, in part, by composition (contourites have abundant siliceous allochems and reworked carbonate) and by evidence of reworking by contour currents. Lithostratigraphic units are labeled at each site.
