Plumbing the depths of magma crystallization using 176 Lu/ 177 Hf in zircon as a pressure proxy

DOI: https://doi.org/10.1130/G50659.1

... to track changes in Earth’s dominant tectonic regimes through time. We therefore developed a new “pressure of crystallization” proxy based on the variation of the 176 Lu/ 177 Hf ratio in zircon. This ratio is controlled by zircon fractionation and residual garnet, and it can be used to monitor...
