- •
Petrogenesis of post-Variscan peraluminous granites in the Cornubian Batholith.
- •
Geochemistry, mineralogy, mineral chemistry and modelling define 5 granite groups.
- •
G1 and G3 formed by partial melting of a metagreywacke with a minor mantle component.
- •
G5 is derived from fluid-fluxed melting of biotite-rich restite in the lower crust.
