Figure F7. Biostratigraphic zonation at Site 1218. Gray shaded bar = interval for which no zonation could be assigned with confidence owing to severe reworking of radiolarian assemblages. Horizontal dashed lines = boundary can only be approximated by available biostratigraphy. Vertical dashed lines = absence of intervening zonal markers prevents further subdivision of the zonation. TD = total depth.
