Figure F24. 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), color reflectance (L*, lightness) (Site 1265 splice, 21-point moving average), and smear slide percentage of foraminifers (open triangles = Hole 1265A and solid triangles = Hole 1265B; solid line is combined 3-point moving average). Occurrence of turbidite (T), volcanic ash (A), chert (C), and chalky layers (Ch) are also shown. See “Biostratigraphy” in the “Site 1265” chapter for derivation of ages.
