Figure F8. Magnetic susceptibility data, chromaticity parameter b*, and percent carbonate for Unit II. Chromaticity parameter b* is smoothed (nine-point moving average). Low values of magnetic susceptibility (here, magnetic susceptibility is plotted inverted) and peaks in b* correspond to the foraminifer-bearing beds that show a high percentage of carbonate. The alternating, laminated facies within Unit II has higher and variable magnetic susceptibility, and lower and variable values of b*. Each magnetic susceptibility low associated with a foraminifer-bearing bed is numbered (numbers are not oxygen isotope stages), and two lows where foraminifer-bearing clayey silt could not be identified in the core are marked "*." Low magnetic susceptibility is also associated with voids in the core (marked "V") and the occurrence of pyrite in burrows (marked "P"). High susceptibility associated with Facies L₁ is marked "T" for turbidite. The carbonate peak of 46.7% at 133.9 mbsf occurs within a carbonate-cemented silt bed.
