Figure F23. Ratios between X-ray diffraction intensities of selected peaks for chlorite (7 Å), illite (5 Å), and mixed-layer (~12 Å) clays in clay-sized sediment fractions from Site 1101. Peak height ratios do not reflect absolute concentrations. For comparison, concentrations of calcite (wt%) are included for samples from Core 178-1101A-10H.
