Abstract [1] Migmatite domes are common in metamorphic core complexes. Dome migmatites deform in the partially molten or magmatic state and commonly record complex form surfaces, folds, and fabrics while units mantling the dome display a simpler geometry, typically formed by transposition during crustal extension.

The study of migmatite complexes provides evidence to decipher the history of late metamorphic and magmatic processes during orogeny, and precise dating of migmatization is essential to model the waning stages of orogenesis.
