K/T Boundary Session

This morning’s extinction session at GSA 2014 brings together geologists, including Gerta Keller and Walter Alvarez, trying to decipher the timing and cause of mass extinction events, including the demise of non-avian dinosaurs. Interesting new research on the Chicxulub Impact and the catastrophic Deccan Traps (massive volcanism in India). Maid the impact trigger even greater volcanism worldwide?
