Figure F9. Synthetic stratigraphic section of Holes 1149A, 1149B, 1149C, and 1149D. Basement depth in the graphic lithology column was arbitrarily set to 407.7 mbsf, where it was observed in Hole 1149B. Note that Hole 1149D was offset ~5 km to reach volcanic basement at a shallower depth. Lines extending from the lithology to the lithologic unit and subunit column represent ash layers.
