Site 1124 showed opal contents ranging from approximately 2 to 8 wt%, which is relatively high compared to other sites. The subbottom maximum in biogenic opal content located between 1.0 and 1.5 m composite depth can be recognized at each site. Patterns of biogenic opal content in the uppermost parts of the cores appear to reflect the surface ocean settings relating to the migration of the Subtropical Convergence Zone.completedOceanographyCenozoicChatham Risecoresdepositional environmentexperimental studiesframework silicateslaboratory studiesLeg 181marine sedimentsmineral compositionOcean Drilling ProgramODP Site 1123ODP Site 1124ODP Site 1125opalPacific OceanQuaternarysedimentssilica mineralssilicatesSouth PacificSouthwest PacificWest Pacificurn:org.iodp:exp:181urnlargerWorkCitationcampaignurn:org.iodp:exp:181:site:1123urnlargerWorkCitationstudyurn:org.iodp:exp:181urnlargerWorkCitationcampaignurn:org.iodp:exp:181:site:1124urnlargerWorkCitationstudyurn:org.iodp:exp:181urnlargerWorkCitationcampaignurn:org.iodp:exp:181:site:1125urnlargerWorkCitationstudyurn:org.iodp:exp:181urnlargerWorkCitationcampaignEnglishgeoscientificInformation-178.0959-171.2956-42.3259-39.2954Data 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/205.PDFdownload
