Figure F7. Site 1265 lithostratigraphic composite illustrating stratigraphic variation in parameters used to define lithostratigraphic units, including magnetic susceptibility (MS) (Site 1265 splice; 21-point moving average), sediment lightness (L*) (Site 1265 splice; 21-point moving average), and smear slide foraminifer percentage (open triangles = Hole 1265A, solid triangles = Hole 1265B; solid line is a combined 3-point moving average). Occurrence of turbidite (T), volcanic ash (A), chert (C), and chalky layers (Ch) are also shown. See "Biostratigraphy" for derivation of ages.
