Sedimentological and clay mineralogical analyses indicate a very fine grained carbonate-rich sediment. Smectite and illite are the main constituents of the clay mineral assemblage. High smectite values in the Eocene decrease in younger sediment sequences. Illite and chlorite concentrations increase in younger sediments with significant steps at 13.5, 9, and 6.4 Ma. The kaolinite content is near the detection limit and not significant. We observed only small fluctuations of the clay mineral composition, which indicates a uniform sedimentation process, probably driven by long-term processes. Good correspondence is shown between increasing illite and chlorite values and the tectonic uplift history of the Southern Alps.completedStratigraphyAustralasiaCenozoicChatham Riseclay mineralogyclay mineralsdepositional environmentLeg 181lithostratigraphymarine sedimentsmineral compositionMioceneNeogeneNew ZealandOcean Drilling ProgramODP Site 1123Pacific OceanpatternsPleistoceneQuaternarysedimentationsedimentssheet silicatessilicatesSouth IslandSouth PacificSouthern AlpsTertiaryurn:org.iodp:exp:181urnlargerWorkCitationcampaignurn:org.iodp:exp:181:site:1123urnlargerWorkCitationstudyurn:org.iodp:exp:181urnlargerWorkCitationcampaignEnglishgeoscientificInformation-171.2956-171.2956-41.4710-41.4710Data 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/181_SR/VOLUME/CHAPTERS/206.PDFdownload
