Cadmium as a tracer of volcanism at the Cretaceous-Paleogene boundary Open
Major volcanic eruptions like the Deccan have long been invoked as causes of global mass extinctions. Deccan volcanism erupted ~ 600,000 km3 over the span of ~ 700 ka contemporaneously with the end-Cretaceous mass extinction. It has been d…
