This interval is globally characterized by significant chemical and biological signals. Ocean Drilling Program Core 199-1221C-11X captured the P/E boundary section at a depth of 154 meters composite depth. Biogenic components of the sediment were measured across this interval in order to better define the events that occurred at the P/E boundary in the equatorial Pacific Ocean. A 26-cm interval low in CaCO (sub 3) was identified, whereas biogenic silica and organic carbon remained unchanged. Although CaCO (sub 3) , biogenic silica, and organic carbon (C-org) production is controlled by different constraints, it is unlikely that an environmental factor would cease production by CaCO (sub 3) -producing organisms without affecting biogenic silica or C-org production. The data indicate that the CaCO (sub 3) P/E boundary event was caused by a change in CaCO (sub 3) preservation rather than a change in CaCO (sub 3) production.completedStratigraphybioclastic sedimentationbiogenic processesburialcalcium carbonatecarbonCenozoicdepositional environmentEoceneEquatorial Pacificframework silicatesgeochemistryLeg 199lower Eocenemarine environmentmarine sedimentsOcean Drilling ProgramODP Site 1221opalorganic carbonPacific Oceanpaleo-oceanographyPaleocenePaleocene-Eocene boundaryPaleogenesedimentationsedimentssilica mineralssilicatesstratigraphic boundaryTertiaryupper Paleoceneurn:org.iodp:exp:199urnlargerWorkCitationcampaignurn:org.iodp:exp:199:site:1221urnlargerWorkCitationstudyurn:org.iodp:exp:199urnlargerWorkCitationcampaignEnglishgeoscientificInformation-143.4200-143.420012.020012.0200Available 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/199_SR/VOLUME/CHAPTERS/215.PDFdownload
