Fingerprinting the cretaceous-paleogene boundary impact with zn isotopes

HIGHLIGHTS

• who: Ryan Mathur from the DepartmentCook University, Townsville, QLD, Australia have published the research: Fingerprinting the Cretaceous-Paleogene boundary impact with Zn isotopes, in the Journal: NATURE COMMUNICATIONS NATURE COMMUNICATIONS of 05/07/2021
• what: Much of this work has been performed on tektites, where a wealth of literature has consistently shown that as heated projectiles (e_g, molten prototektites) travel along their ballistic trajectories, Zn volatilization results in lower Zn concentrations and heavy Zn isotope enrichment (high δ66Zn in per mil, ‰) in the residuum16,17.
• future: The light Zn isotope reservoir required for . . .
