We particularly focus on key time intervals of enhanced faunal turnover, extinction, recovery and diversification in response to severe global disruptions of the geobiosphere: \r\n\r\n•\tCretaceous-Tertiary boundary (66 Ma) – mass extinction related to the Chicxulub impact in the Gulf of Mexico\r\n•\tPaleocene-Eocene thermal maximum (56 Ma) – rapid global warming, deep-sea extinction and decline of coral reefs \r\n•\tLatest Danian Event (62 Ma) and the Eocene Thermal Maximum 2 (54 Ma) – restructuring of deep-sea ecosystems in response to milder global warming events\r\n\r\nMuch of this research is carried out in collaboration within the global Paleogene community. The foundation for our research is provided by core material retrieved through the US Geological Survey, and international drilling programs (DSDP, ODP, IODP) and by outcrop studies in Europe, Asia and Africa.\r\n\r\nOur key study material consists of microfossils of Foraminifera, ubiquitous marine single-celled organisms with a fossil record extending as far back as the Cambrian, over 500 million years ago. We combine research on Foraminifera with other microfossil groups (e.g. calcareous nannofossils, Ostracoda) and geochemical, mineralogical and sedimentological analyses in order to understand key moments of earth history and to provide insight into the possible consequences of future global warming on marine life.","AbstractOtherLang":"De onderzoeksgroep Biogeologie (afdeling Geologie) bestudeert de verbanden tussen milieu- en biotische veranderingen tijdens de laatste 70 miljoen jaar door de analyse van mariene microfossielen en de sedimenten die deze bevatten. De groep richt zich hoofdzakelijk op cruciale tijdsintervallen van faunale veranderingen, extincties, herstel en diversificatie als reactie op ernstige wereldwijde verstoringen van de geobiosfeer: \r\n•\tKrijt-Tertiair grens (66 Ma) - massa-extinctie in verband met de impact van Chicxulub in de Golf van Mexico;\r\n•\tPaleocene-Eocene Thermal Maximum (56 Ma) - snelle opwarming van de aarde, diepzee-extincties en achteruitgang van koraalriffen; \r\n•\tLaatste Danien Event (62 Ma) en het Eocene Thermal Maximum 2 (54 Ma) - herstructurering van diepzee-ecosystemen als reactie op de mildere opwarming van de aarde.\r\n\r\nVeel van dit onderzoek wordt uitgevoerd in samenwerking met de globale Paleogene onderzoeksgemeenschap. Het onderzoek richt zich op boorkernen, bekomen via de US Geological Survey en internationale boorprogramma's (DSDP, ODP, IODP), en op ontsluitingen in Europa, Azië en Afrika.\r\n\r\nHet belangrijkste studiemateriaal bestaat uit microfossielen van Foraminifera. Dit zijn alomtegenwoordige mariene ééncellige organismen met een fossielenbestand dat zich uitstrekt tot in het Cambrium, meer dan 500 miljoen jaar geleden. Het onderzoek naar Foraminifera wordt gecombineerd met andere groepen microfossielen (bv. kalkhoudende nannofossielen, Ostracoda) en met geochemische, mineralogische en sedimentologische analyses teneinde sleutelmomenten in de geschiedenis van de aarde beter te begrijpen en inzichten te verschaffen in de mogelijke gevolgen van een toekomstige opwarming van de aarde voor het mariene leven.","AbstractLangCode":null,"AbstractLangID":null,"AbstractLang":null,"AbstractLangNL":null,"SuccessorOfInsID":null,"DateLastModified":{"date":"2024-06-04 01:34:19.073000","timezone_type":1,"timezone":"+00:00"},"PrevIns":null,"PrevAcro":null,"PublicFlag":1,"CheckedFlag":0,"ParID":2957,"InstituteType":"Scientific","EnvName":"Belgium","ISO3166":"BE","LevelName":null,"ND":"2019-01-29","UD":"2022-06-15","EncAddress":", Celestijnenlaan 200E, box 2408, 3001 Heverlee, Belgium"},"parent":{"PublicFlag":1,"InsID":9768,"OrigNameLangCode":"en","OrigNameLangID":15,"FullStandardName":"Katholieke Universiteit Leuven; Departement Aard- en Omgevingswetenschappen; Afdeling Geologie","FullOrigName":"University of Leuven; Department of Earth and Environmental Sciences; Division of Geology","Acronym":"KULeuven"},"institutes":null,"references":[{"BRefID":361562,"RR":"<b>Wagner, C.L.; Stassen, P.; Thomas, E.; Lippert, P.C.; Lascu, I.</b> (2022).
