[Extract] For a long time, discussions about granulite metamorphism focussed on the presence or absence of free fluids, i.e. vapour-absent vs. fluid-assisted granulite metamorphism. We consider that this debate has come to an end at the satisfaction of both parties (e.g., Touret, 2009)and that it is the right time now to consider its consequences within the context of the Earth's evolution. Most granulites have a long, complicated P-T-t history, which can only be unravelled through mineral phase equilibrium, pseudosection analysis, and single zircon dating. These research methodologies, which have reached a great degree of sophistication during the last 10 years, have resulted in a better understanding of granulite forming processes related to continent formation.
