Figure F13. Compilation of lithologic and stratigraphic information of Core 189-1172D-39X sediments (Unit IV, Eocene-Oligocene Transition). The paleomagnetostratigraphic data series seems not to match the exact depth interval. The ash layer identified in the lithologic column is suspected to be responsible for the intensity peak at 358 mbsf. See Figure F3 in the "Explanatory Notes" chapter for the key to lithologic and bioturbation symbols. P = planktonic foraminifers, D = diatoms, N = nannofossils, Dino = dinocysts.
