This session will investigate how massive volcanism and meteorite impacts may have caused mass extinctions and global environmental crises. We hope to bring together researchers across the geological, geophysical, and biological disciplines to present new and exciting research. The session will focus on the four main Mesozoic and Cenozoic crises (end-Permian, end-Triassic, end-Cretaceous, and the Paleocene-Eocene Thermal Maximum (PETM)), but contributions from theoretical studies or from other environmental crises are also welcome.
