Preservation of calcareous nannoflora assemblages varies from poor to good throughout the sediments recovered from both Holes 1203A and 1204A. Biostratigraphic investigation allowed the identification of 19 nannofossil zones in Hole 1203A and 7 in Hole 1204A. The sedimentary cover in Hole 1203A ranges from lower Eocene (Zone NP12) to upper Miocene (Zone NN9). The sedimentary interval investigated directly overlying the basalt recovered at Hole 1204A is late Campanian in age (Zones CC22-CC23), and the top of the section is middle Eocene (Zone NP15) in age. Major unconformities were observed in Hole 1204A between upper Campanian (Zones CC22-CC23) and lower Thanetian (Zone NP7) sediments and between upper Thanetian (Zone NP8) and upper Ypresian (Zone P12) sediments.completedStratigraphyalgaebiostratigraphybiozonesCenozoicDetroit SeamountEmperor SeamountsLeg 197microfossilsMiocenenannofossilsNeogeneNorth PacificNorthwest PacificOcean Drilling ProgramODP Site 1203ODP Site 1204Pacific OceanPaleocenePaleogenePlantaeTertiaryunconformitiesWest Pacificurn:org.iodp:exp:197urnlargerWorkCitationcampaignurn:org.iodp:exp:197:site:1203urnlargerWorkCitationstudyurn:org.iodp:exp:197urnlargerWorkCitationcampaignurn:org.iodp:exp:197:site:1204urnlargerWorkCitationstudyurn:org.iodp:exp:197urnlargerWorkCitationcampaignEnglishgeoscientificInformation167.4400167.460050.570051.1200Data report; available only on CD-ROM in PDF format and on the Web in PDF or HTMLapplication/pdfunknownSEDIS Publication Catalogueana.macario@awi.dehttp://sedis.iodp.org/pub-catalogue/informationpointOfContacthttp://www-odp.tamu.edu/publications/197_SR/VOLUME/CHAPTERS/003.PDFdownload
