Decoupling of zircon U–Pb and trace-element systematics driven by U diffusion in eclogite-facies zircon (Monviso meta-ophiolite, W. Alps)

Zircon is widely used to date metamorphic processes, particularly due to slow cation diffusion under crustal conditions. Here, we present laser-ablation depth profiling data that demonstrate rapid U diffusion in partially altered, high-pressure zircon. The zircons are hosted in metagabbros that unde...
