Figure F2. Neogene recovery, lithologic units, tephra horizons, and relative diatom and nannofossil abundance, Hole 1138A. Abundance estimates: B = Barren, X = present, R = rare, F = few, C = common, and A = abundant. Red horizontal bars in tephra column = positions of tephra horizons identified in shipboard core descriptions (Coffin, Frey, Wallace, et al., 2000), * = tephra horizons considered in this study.
