Useful Oligocene dinocyst events are the last occurrence of Enneadocysta pectiniformis (similar to29.3 Ma), and the first occurrences of Saturnodinium pansum (similar to29.4 Ma), Distatodinium biffii (similar to27.9 Ma) and Artemisiocysta cladodichotoma (similar to26.7 Ma). The latter event marks the earliest Chattian. The improved correlations indicate that the Rupelian-Chattian (R-C) boundary is associated with the so-called 'Oligocene Glacial Maximum'. This phase of important global cooling and glacio-eustatic sea level fall is genetically related to the unconformity between the classic Oligocene stages. Subsequent global warming (so-called 'Late Oligocene Warming Event'), induced a major sea level rise, leading e.g. to the time-transgressive deposition of the typical basal Chattian glauconitic sands. The oldest of the Chattian units have a GPTS age of similar to26.7 Ma. It further appears that a hiatus of similar to500 kyrs spans the classic Rupelian-Chattian unconformity.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"The Rupelian-Chattian boundary in the North Sea Basin and its calibration to the international time-scale","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"biochronostratigraphy; dinoflagellate cysts; North Sea Basin;Rupelian-Chattian boundary; Tethyan Ocean","OtherDescriptors":null,"Notes":null,"AnaPub":2004,"MonPub":null,"DateUpdate":"2013-12-17","DateCreate":"2013-12-01","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000226328500010","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":231709,"PubliDate":2004,"Pagination":"241-248","XtraPublOfAnaID":null,"ISBN":null,"Volume":"83","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42914,"SerRR":"Netherlands Journal of Geosciences.
