Short summary
We present a pioneering method for high-precision U–Pb dating of individual growth zones in zircon. These micrometer zones in single grains can record key geological processes from magma priming prior to eruptions to planetary formation, yet dating them at high precision has so far been technically challenging. Our method employs two cutting-edge microbeam techniques to microsample these growth zones for high-precision dating, allowing us to tackle a number of outstanding research questions.
