No evidence was found to support the idea that the sediments experienced horizontal ductile strain during their residence, although there was evidence for increasing fabric magnitude with depth, associated with burial and dewatering. A crude, approximately linear, relationship is inferred between discrete water contents and apparent volumetric strains derived from the measured fabric, which may correlate with fabric-strain relationships observed in other settings.completedStructural geologyAtlantic OceanburialCenozoicclay mineralscompression tectonicsdeformationEuropefabricIberian abyssal plainIberian PeninsulaLeg 149MioceneNeogeneNorth AtlanticNortheast AtlanticOcean Drilling ProgramODP Site 897ODP Site 898ODP Site 899physical propertiesplate tectonicsriftingsheet silicatessilicatesSouthern Europestressstructural analysissyntectonic processestectonicsTertiaryX-ray dataurn:org.iodp:exp:149urnlargerWorkCitationcampaignurn:org.iodp:exp:149:site:897urnlargerWorkCitationstudyurn:org.iodp:exp:149urnlargerWorkCitationcampaignurn:org.iodp:exp:149:site:898urnlargerWorkCitationstudyurn:org.iodp:exp:149urnlargerWorkCitationcampaignurn:org.iodp:exp:149:site:899urnlargerWorkCitationstudyurn:org.iodp:exp:149urnlargerWorkCitationcampaignEnglishgeoscientificInformation-12.2847-12.072540.410640.5019application/pdfunknownSEDIS Publication Catalogueana.macario@awi.dehttp://sedis.iodp.org/pub-catalogue/informationpointOfContacthttp://www-odp.tamu.edu/publications/149_SR/VOLUME/CHAPTERS/SR149_19.PDFdownload
