The restored vertical section through the upper and middle crust consists of three megalayers with undulating boundaries: (1) 0 to < 10 km, a metavolcanic-metasedimentary succession ("greenstone belts") with discordant plutons; (2) < 10 to ∼20 km, tabular batholiths of gneissic and xenolithic tonalite and granodiorite; and (3) from 20 to >25 km, a high-grade heterogeneous gneissic assemblage, in part older than the upper supracrustal succession.
