Figure F5. Core recovery, lithology, lithologic units, age with corresponding biostratigraphic zonations, color reflectance (at 550 nm), and percent carbonate for Hole 1207A. Depth is shown on the far left. Reflectance and percent carbonate data both illustrate the lithologic transition downcore from a greenish colored, less oxidized clayey nannofossil ooze to a lighter-colored, more oxidized nannofossil ooze. The prominent spike in the reflectance data coincides with a substantial hiatus or condensed interval between Campanian- and mid-Miocene-age sediment. Foram. zn. = foraminiferal zone, nanno. zn. = nannofossil zone.
