Comparison of the Cretaceous-Tertiary boundary impact events and the 0.77-Ma Australasian tektite event : relevance to mass extinction /

Reinterpretation of iridium anomalies, shocked quartz, and microtektites attributed to cratering events in Cretaceous-Tertiary boundary sections. Evidence from the Ries crater of Germany and Australasian tektites is essential to understanding giant craters and mass extinction.
