Two holes, 1179B and 1179C, yielded an upper Miocene to Pleistocene diatom record through an expanded section with excellent recovery. Because diatom species included in both low-latitude and high-latitude biostratigraphies are present, zonations for the equatorial Pacific and northwest Pacific are applied to the sediments. The oldest zones from each zonation that are represented in the cores are the Nitzschia miocenica Zone and the Rouxia californica Zone, respectively. Only one zonal boundary is not observed within the diatom assemblage, that being the top of the Nitzschia jouseae Zone and base of the Rhizosolenia praebergonii Subzone A (equatorial Pacific). Preservation is good overall, and sample abundances vary from rare to abundant. This would be an excellent section for further biostratigraphic, paleoclimatic, and paleoceanographic study.completedStratigraphyalgaeassemblagesbiostratigraphybiozonesCenozoicdiatomsLeg 191marine environmentmarine sedimentsmicrofossilsMioceneNeogeneNorth PacificNorthwest PacificOcean Drilling ProgramODP Site 1179Pacific Oceanpaleo-oceanographypaleoenvironmentPlantaePleistocenePlioceneQuaternarysedimentsShatsky RiseTertiaryupper MioceneWest Pacificurn:org.iodp:exp:191urnlargerWorkCitationcampaignurn:org.iodp:exp:191:site:1179urnlargerWorkCitationstudyurn:org.iodp:exp:191urnlargerWorkCitationcampaignEnglishgeoscientificInformation159.5700159.580041.040041.0500Includes appendix; 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/191_SR/VOLUME/CHAPTERS/009.PDFdownload
