Metapelitic migmatites at Brattstrand Bluffs, East Antarctica, preserve granulite assemblages and a complex deformational history. Crystallized granitic melt accounts for ∼25% of exposed rocks, and was produced by biotite dehydration-melting reactions in the host metapelite. Variable degrees of melt...
