Most samples have organic delta (super 13) C values smaller than -27 per mil, with the exception of several samples that have values between -24.9 per mil and -23.9 per mil that may correspond to oceanic anoxic events. Bulk delta (super 15) N values range between -4.2 per mil and +4.4 per mil and become smaller as organic carbon concentrations increase. Comparison of the delta (super 15) N values of nondecarbonated samples to their decarbonated analogs reveals no systematic effect of the acid treatment used in the decarbonation.completedIsotope geochemistryAtlantic Oceanblack shaleboreholesC-13/C-12calcium carbonatecarbonchemical ratioschemostratigraphyclastic rocksconcentrationcontinental marginCretaceousDemerara RiseEquatorial AtlanticFrench Guianageochemistryisotope ratiosisotopesLeg 207MesozoicN-15/N-14nitrogenNorth AtlanticNorthwest AtlanticOcean Drilling ProgramODP Site 1257ODP Site 1258ODP Site 1259ODP Site 1260ODP Site 1261oresorganic carbonorganic compoundsregression analysissedimentary rocksSouth Americastable isotopesstatistical analysisSurinamtotal organic carbonwestern Equatorial Atlanticurn:org.iodp:exp:207urnlargerWorkCitationcampaignurn:org.iodp:exp:207:site:1257urnlargerWorkCitationstudyurn:org.iodp:exp:207urnlargerWorkCitationcampaignurn:org.iodp:exp:207:site:1258urnlargerWorkCitationstudyurn:org.iodp:exp:207urnlargerWorkCitationcampaignurn:org.iodp:exp:207:site:1259urnlargerWorkCitationstudyurn:org.iodp:exp:207urnlargerWorkCitationcampaignurn:org.iodp:exp:207:site:1260urnlargerWorkCitationstudyurn:org.iodp:exp:207urnlargerWorkCitationcampaignurn:org.iodp:exp:207:site:1261urnlargerWorkCitationstudyurn:org.iodp:exp:207urnlargerWorkCitationcampaignEnglishgeoscientificInformation-54.4400-54.11009.02009.2800application/pdfunknownSEDIS Publication Catalogueana.macario@awi.dehttp://sedis.iodp.org/pub-catalogue/informationpointOfContacthttp://www-odp.tamu.edu/publications/207_SR/VOLUME/CHAPTERS/106.PDFdownload
