Figure F13. Age-depth plot of calcareous nannofossil and diatom datum events at Site 1088, using data from Holes 1088B and 1088C. Age-depth control points are based on 24 calcareous nannofossil datums and one diatom datum (Table T3, p. 45). The horizontal bars indicate the range of the diatom zones. Numbers refer to the following diatom zones: 1 = T. insigna, 2 = F. reinholdii, 3 = D. dimorpha, and 4 = A. ingens var. nodus. The solid lines indicate a visual best fit through the age-depth control points. Corresponding sedimentation rate averages are given in parentheses.
