Figure F23. Age model and correlation of the composite magnetic polarity record for Site 1123. Magnetic polarity interpretations are given in Figure F19, and individual reversal ages are from Berggren et al. (1985). Solid black line shows line of correlation. Undulating line indicates a hiatus. Lithostratigraphic summary is from "Lithostratigraphy" in the "Site 1123" chapter. Ages of tephra horizons are assigned from the age-depth model (Table T11). The main features are discussed in "Age Models and Sedimentation Rates" in the "Site 1123" chapter.
