Figure F3. A. Diffractograms of Samples 184-1148A-3H-6, 25-27 cm (black line), and 3H-6, 28-30 cm (gray line), <2-µm glycolated fraction. B. Diffractograms of Samples 184-1148A-5H-4, 52-54 cm (gray line), and 5H-4, 49-51 cm (black line), <2-µm glycolated fraction. IS = illite/smectite, with 80%-85% of Fe-rich muscovite; CS = chlorite/smectite, with 75%-80% of chlorite. Mixed-layered clays are estimated as described in Moore and Reynolds (1997). sed. = sediment.
