p.31: The Mesozoic–Cenozoic sedimentary sequences of the Helvetic units were deposited on a Proterozoic–Paleozoic crystalline basement belonging to the European continental margin. Parts of this basement constitute the External Crystalline Massifs (Belledonne, Aiguilles Rouges, Mont Blanc, Aar, Gotthard; the latter recently classified as a nappe) which, together with their attached autochthonous and parautochthonous sedimentary cover, represent real tectonic units.
