(editor), Saunders, Andrew D. (editor), Origin and evolution of the Ontong Java Plateau22983-111The Lower Cretaceous sediments of the Ontong Java Plateau of the SW Pacific Ocean provide a depositional history for the period immediately following the termination of one of the largest extrusive igneous events of the Phanerozoic eon. A more complete stratigraphic record is formulated of this critical event in Earth's history than previously available by integration of previous data and new analyses from DSDP Leg 30 sites combined with shipboard and post-cruise analyses from ODP Leg 192. The oldest sediment occurs within the upper part of the Leupoldina cabri planktonic foraminiferal zone, indicating equivalence with the last half of Oceanic Anoxic Event (OAE) 1a of which the Ontong Java eruption is a postulated cause. The remainder of the Aptian section is marked by major disconformities, with little section in common between central and marginal plateau sites. The Aptian-Albian boundary is conformable at both Leg 192 Sites 1183 and 1186 based on integration of biostratigraphy and preliminary delta (super 13) C data. However, the overall Albian interval is very incomplete, with regional distribution noted for only the lowermost and upper Albian sections.completedStratigraphyAlbianalgaeAptianassemblagesbiostratigraphybiozonescorrelationCretaceousDeep Sea Drilling ProjectDSDP Site 288DSDP Site 289ForaminiferaInvertebrataLeg 192Leg 30Leupoldina cabriLower CretaceousMesozoicmicrofossilsnannofossilsOcean Drilling ProgramODP Site 1183ODP Site 1185ODP Site 1186ODP Site 1187Ontong Java PlateauPacific OceanpaleobathymetryPlantaeProtistaWest Pacificurn:org.iodp:exp:192urnlargerWorkCitationcampaignurn:org.iodp:exp:30urnlargerWorkCitationcampaignurn:org.iodp:exp:30:site:288urnlargerWorkCitationstudyurn:org.iodp:exp:30urnlargerWorkCitationcampaignurn:org.iodp:exp:30:site:289urnlargerWorkCitationstudyurn:org.iodp:exp:30urnlargerWorkCitationcampaignurn:org.iodp:exp:192:site:1183urnlargerWorkCitationstudyurn:org.iodp:exp:192urnlargerWorkCitationcampaignurn:org.iodp:exp:192:site:1185urnlargerWorkCitationstudyurn:org.iodp:exp:192urnlargerWorkCitationcampaignurn:org.iodp:exp:192:site:1186urnlargerWorkCitationstudyurn:org.iodp:exp:192urnlargerWorkCitationcampaignurn:org.iodp:exp:192:site:1187urnlargerWorkCitationstudyurn:org.iodp:exp:192urnlargerWorkCitationcampaignEnglishgeoscientificInformation153.0000176.0000-27.00001.0000
