Lithologic and seismostratigraphical studies, as well as paleomagnetic, calcareous nannofossil, foraminiferal, and dinocyst stratigraphic research, were completed. The depositional history of the Iberia Abyssal Plain is generally characterized by downslope transport of terrigenous sediments, pelagic sedimentation, and contourite sediments. Sea-level changes and catastrophic events such as slope failure, triggered by earthquakes or oversteepening, are the main factors that have controlled the different sedimentary facies. We propose five stages for the evolution of the Iberia Abyssal Plain: (1) Upper Cretaceous and lower Tertiary gravitational flows, (2) Eocene pelagic sedimentation, (3) Oligocene and Miocene contourites, (4) a Miocene compressional phase, and (5) Pliocene and Pleistocene turbidite sedimentation. Major input of terrigenous turbidites on the Iberia Abyssal Plain began in the late Pliocene at 2.6 Ma.completedStratigraphyAtlantic OceanCenozoiccontouritecoresCretaceousdepositional environmentEuropeIberian abyssal plainIberian PeninsulaLeg 149lithofacieslithostratigraphyMesozoicMioceneNeogeneNorth AtlanticNortheast AtlanticOcean Drilling ProgramODP Site 897ODP Site 898ODP Site 899ODP Site 900ODP Site 901paleoenvironmentpelagic environmentPleistoceneQuaternaryrift zonessea-level changesseismic stratigraphyslope stabilitySouthern Europesynsedimentary processesTertiaryurn: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:149urnlargerWorkCitationcampaignurn:org.iodp:exp:149:site:900urnlargerWorkCitationstudyurn:org.iodp:exp:149urnlargerWorkCitationcampaignurn:org.iodp:exp:149:site:901urnlargerWorkCitationstudyurn:org.iodp:exp:149urnlargerWorkCitationcampaignEnglishgeoscientificInformation-11.3616-11.033540.402940.4059application/pdfunknownSEDIS Publication Catalogueana.macario@awi.dehttp://sedis.iodp.org/pub-catalogue/informationpointOfContacthttp://www-odp.tamu.edu/publications/149_SR/VOLUME/CHAPTERS/SR149_45.PDFdownload
