Abstract
Cretaceous-Tertiary (K-T) boundary clays from five sites in Europe and New Zealand are 102-104-fold enriched in elemental C (mainly soot), which is isotopically uniform and apparently comes from a single global fire. The soot layer coincides with the Ir layer, suggesting that the fire was triggered by meteorite impact and began before the ejecta had settled.
