State shift in Deccan volcanism at the Cretaceous-Paleogene boundary, possibly induced by impact

Making an impact in more ways than one Massive eruptions formed the Deccan Traps flood basalts in India at around the same time as the mass extinction event 65 million years ago. Renne et al. precisely dated the massive volcanic field, which suggests a simultaneous increase in volcanism associated with the famous Chicxulub impact. Strong ecologic recovery may have been impossible until the volcanism slowed down 500,000 years later. Science ,...
