Figure F10. Correlation between multichannel seismic line A-A´ (Fig. F7), the Site 1179 lithostratigraphic column, and predicted depths of unit boundaries. The lithostratigraphic column was scaled to the seismic section using the velocity-depth relationship of Carlson et al. (1986) to calculate the two-way traveltime of unit boundaries and ash layers derived from core observations. In the lithostratigraphic column solid lines = unit boundaries, dashed lines = ash layers. Lithologic boundary depths are given next to the column.
