PP23B:
Global Change During and After the K-Pg and P-E Transitions II Posters

Submit an Abstract to this Session



Session ID#: 25693

Session Description:
Geochemical, paleontological, and geophysical approaches have been effectively used for exploring abrupt physical and climatic changes related to the Chicxulub impact, K-Pg transition and P-E transition. Multiproxy approaches have been proven successful to solve major scientific questions.

This session aims to bring together investigators working on global changes during the late Cretaceous and early Paleogene. We invite contributions focusing on the immediate physical effects of the Chicxulub impact, as well as studies that employ modeling and/or analytical proxy approaches involving sedimentology, mineralogy, paleontology and chemistry (major and trace elements, as well as isotopes in foraminifera and bulk sediments) that allow for paleoclimatic and paleoceanographic reconstructions of the K-Pg transition and climatic events of the Paleogene such as the PETM and other hyperthermals.

We welcome submissions related to (but not limited to) results from recent drilling of the Chicxulub crater in the Gulf of Mexico done by the IODP-ICDP Expedition 364.
