Fingerprinting the Cretaceous-Paleogene boundary impact with Zn isotopes

Fingerprinting the Cretaceous-Paleogene boundary impact with Zn isotopes

Elevated Zn isotope compositions occur in K-Pg sedimentary layers of three different depositional environments across North America and the Caribbean. The data indicate a volatilization event, and act as a robust mechanistic indicator of the meteorite impact at the end of the Cretaceous.
