The small thickness of the Upper Cenomanian-Turonian in the South Atlantic Ocean is related to erosive events. These occurred respectively in the late Cenomanian-early Turonian (Biozones UC-5/UC-6), mid-Turonian (Biozones UC-6b and UC-7). In addition, two important transgressive events have been recognized; the global event late Cenomanian-early Turonian (Biozones UC-5c/UC-6a), and a mid-Turonian event (Biozone UC-8), registered in the northern part of the South Atlantic Ocean. Such events resulted from modifications in oceanic circulation patterns induced by the break-up of the equatorial portion of South America from Africa, and from changes in the uplift rates of the mid-oceanic ridge and spreading rate of the oceanic bottom.completedStratigraphyEconomic geology, geology of energy sourcesalgaeAngola BasinAtlantic Oceanbasin analysisbasinsbiostratigraphybiozonesBrazilcalcareous compositionCenomaniancontinental driftcontinental margincorrelationCretaceousDeep Sea Drilling ProjectDSDP Site 364DSDP Site 511DSDP Site 530erosionFalkland Plateaugamma-ray methodsIPODLeg 40Leg 71Leg 75Mesozoicmicrofossilsmid-ocean ridgesnannofossilsocean circulationOcean Drilling Programocean floorsoffshorepaleoenvironmentpetroleumpetroleum explorationPlantaeplate tectonicsSantos Basinsea-floor spreadingsea-level changessedimentary basinsSergipe-Alagoas BasinSouth AmericaSouth AtlantictectonicstransgressionTuronianupliftsupper CenomanianUpper Cretaceouswell-loggingurn:org.iodp:exp:40urnlargerWorkCitationcampaignurn:org.iodp:exp:71urnlargerWorkCitationcampaignurn:org.iodp:exp:75urnlargerWorkCitationcampaignurn:org.iodp:exp:40:site:364urnlargerWorkCitationstudyurn:org.iodp:exp:40urnlargerWorkCitationcampaignurn:org.iodp:exp:71:site:511urnlargerWorkCitationstudyurn:org.iodp:exp:71urnlargerWorkCitationcampaignurn:org.iodp:exp:75:site:530urnlargerWorkCitationstudyurn:org.iodp:exp:75urnlargerWorkCitationcampaignPortuguesegeoscientificInformation-46.581811.5818-51.0017-11.3419
