Mobilization of radiogenic Pb in zircon revealed by ion imaging: Implications for early Earth geochronology

Zircon is arguably the most commonly used geochronometer, but the reliability of agesobtained requires a full understanding of processes that might compromise the integrity of itsU-Pb systematics. Here we present the results of a multifaceted ion microprobe study of zircongrains from the Napier Comp... View More
