Figure F22. Age-depth plot of Neogene calcareous nannofossil datums (diamonds) and geomagnetic reversals (squares) from Hole 1256B. Nannofossil datum ages and depths are given in Table T7 (see also "Biostratigraphy"), and geomagnetic reversal ages and depths are given in Table T9 (see also "Paleomagnetism"). FO = first occurrence, LO = last occurrence.
