[S-GL22] Frontier research on chronostratigraphic unit boundaries

Fri. May 26, 2023 10:45 AM - 12:00 PM International Conference Room (IC) (International Conference Hall, Makuhari Messe)

convener:Hiroyuki Hoshi(Department of Earth Sciences, Aichi University of Education), Reishi Takashima(Tohoku University Museum, Tohoku University), Junichiro Kuroda(Department of Ocean Floor Geoscience, Atmosphere and Ocean Research Institute, the University of Tokyo), Makoto Okada(Department of Earth Sciences, College of Science, Ibaraki University), Chairperson:Hiroyuki Hoshi(Department of Earth Sciences, Aichi University of Education), Reishi Takashima(Tohoku University Museum, Tohoku University), Junichiro Kuroda(Department of Ocean Floor Geoscience, Atmosphere and Ocean Research Institute, the University of Tokyo), Makoto Okada(Department of Earth Sciences, College of Science, Ibaraki University), Tetsuji Onoue(Department of Earth and Planetary Sciences, Faculty of Science, Kyushu University)

This session aims to share the current knowledge on stratigraphy, geochronology, geochemistry, paleoclimatology, and paleoceanography at or around chronostratigraphic unit boundaries. Geological studies dealing with chronostratigraphic unit boundaries, such as the Permian-Triassic (P-T) and Cretaceous-Paleogene (K-Pg) boundaries, as well as boundaries between systems (periods), series (epochs), stages (ages), and other chronozones (chrons) are welcome. We also welcome studies on global events such as oceanic anoxic events (OAEs), asteroid impacts, and geomagnetic reversals, as well as the lithostratigraphy, sequence stratigraphy, biostratigraphy, chemostratigraphy, magnetostratigraphy, radiometric dating, tectonics, etc. of rock sequences above or below the chronostratigraphic unit boundaries in Japan and elsewhere.

11:00 AM - 11:15 AM
