Figure F10. Comparison of (A) quartz concentrations and (B) kaolinite/(kaolinite + smectite) (k/[k + sm]) values from Hole 1076A with (C) quartz concentrations and (D) kaolinite/(kaolinite + smectite) values from Hole 1077A over the past 1.4 m.y. Glacial isotope Stages 2-50 from the SPECMAP timescale (2-22) (Imbrie et al., 1984) and Ruddiman et al., (1989) (22-50) are shaded.
