Figure F24. Age-depth plot based on first and last occurrences datums (FOs and LOs) of microfossils at Site 1276 and DSDP Site 398. Dashed lines represent intervals in which no samples were analyzed, age-diagnostic datums are uncertain, or in which samples were found to be barren. Approximate sedimentation rates at Site 1276 which are based on calcareous nannofossils are shown in blue, while those based on palynomorphs are depicted in red.
