Figure F27. Site 1266 lithostratigraphic composite illustrating stratigraphic variation in parameters used to define lithostratigraphic units. The Unit I/II boundary was chosen at an abrupt step change in chromaticity value b*, lightness (L*), inflection in magnetic susceptibility (MS), and decrease in foraminiferal abundance. The Unit II/III boundary was chosen at a decrease in L* and increase in MS and natural gamma radiation (NGR). All data are smoothed with a 5-point moving average with the exception of NGR and smear slide components, which were smoothed with a 10-point and 3-point moving average, respectively.
