Figure F14. Site 1264 lithostratigraphic composite illustrating chromaticity (a*) and manganese and iron concentrations in the interstitial waters and grain density in Hole 1264A. Gray lines at ~135, ~165, and ~235 mcd mark slight but abrupt steps in grain density associated with dramatic changes in the interstitial water Mn and Fe concentrations.
