Fingerprinting the Cretaceous-Paleogene boundary impact with Zn isotopes

R. Mathur, B. Mahan, et al.

This paper uncovers compelling zinc isotope data from the Cretaceous-Paleogene boundary, highlighting significant variations compared to neighboring rocks and carbonaceous chondrites. The findings suggest that Zn volatilization during the impact event left a unique isotopic signature, shedding light on this historic cataclysm. This research was conducted by Ryan Mathur, Brandon Mahan, Marissa Spencer, Linda Godfrey, Neil Landman, Matthew Garb, D. Graham Pearson, Sheng-Ao Liu, and Francisca E. Oboh-Ikuenobe.
