Figure F23. Age-depth plot showing cores (every fifth core shaded) in Hole M0028A, the timescale of Berggren et al. (1995), calcareous nannoplankton zones (light blue bars), planktonic foraminifer zones (dark blue bars), and dinocyst zones (green bars). Sr isotopic ages are shown as circles with errors of ±0.6 m.y. (older than 15.2 Ma) and ±1.17 m.y. (younger than 15.2 Ma). Boxes are ages from magnetochronology. Horizontal lines for sequence boundaries (red) and tentative sequence boundaries (dashed red) lines are labeled with their corresponding depths. Green lines = flooding surfaces, blue lines = transgressive surfaces. Planktonic foraminifer M, PL, and Pt zones are from Berggren et al. (1995); nannofossil zones are from Martini (1971); and dinocyst zones are from de Verteuil and Norris (1996). Geomagnetic polarity timescale is from Cande and Kent (1995). LcO = last common occurrence.
