Figure F141. Age-depth plots based on first and last occurrence datums (FOs and LOs) of microfossils at ODP Site 1276 and DSDP Site 398. Dashed lines represent intervals in which no samples were analyzed, age-diagnostic datums are uncertain, or samples were found to be barren. Approximate sedimentation rates at Site 1276 are shown for straight-line segments through median depths of key calcareous nannofossil and palynomorph FOs and LOs. Datums used to construct age-depth plots at Site 1276 are listed in Table T12, ; datums used to construct age-depth plots at Site 398 are listed in Table T13, .
