Pressure plays a primary role in controlling the formation and compositional diversity of tonalite-trondhjemite-granodiorite suites, with “high-pressure” variants derived from fluid-fluxed melting during subduction, recording the onset of global subduction at ~3.0 Ga, according to thermodynamic-geochemical modeling and mineral hygrometry analysis.
