Figure 11. Depth-age relationship for Site 1096 based on geomagnetic reversals (X) and diatom (solid symbols) and radiolarian (open symbols) datums. Paleomagnetic data were drawn from shipboard analysis of cores. Intervals of diatom and radiolarian datums are marked with an upright triangle at the base and an inverted triangle at the top. In labels indicating species identity, B = base/first occurrence and T = top/last occurrence. Sedimentation rates (underlined) for selected intervals are adjacent to the corresponding curve. Vertical solid arrows indicate dominant age diagnostic fossil type (biosiliceous vs. calcareous) for respective intervals of this site. The dashed vertical line below B Fragilariopsis interfrigidaria datum interval indicates range of published ages for this datum.
