Deutsch: Mont-Blanc-Massiv Français: Massif du Mont Blanc Italiano: Massiccio del Monte Bianco English: Mont Blanc Massif
The Mont Blanc Massif, divided into an external and an internal part by a major fault, is a Lower Helvetic External Massif of the French and Western Swiss Alps. It is constituted of a pre-Variscan polycyclic basement (Precambrian to Early Cretaceous) intruded by Variscan granites and of a Mesozoic–Cenozoic sedimentary cover. The Mont Blanc Massif is separated from the Belledonne Massif by the axial depression of the Val Montjoie and from the Aiguilles Rouges Massif by a thin band of Mesozoic sediments often («Chamonix Syncline»).

Deutsch: Puschlin-Zone Français: Zone de Puschlin Italiano: Zona di Puschlin English: Puschlin Zone
Within the Landeck Quarzphyllites, the «Puschlin Zone» encompasses very small lenses of Permo-Carboniferous and Early Triassic slivers (metaconglomerates, metasandstones and phyllites, as well as cataclasites).
Deutsch: Drusberg-Decke Français: Nappe du Drusberg Italiano: Falda del Drusberg English: Drusberg Nappe
Within the Upper Helvetic, the Drusberg Nappe, together with the Axen Nappe, represents the continuation of the Wildhorn Nappe Complex east of the Kander Valley. The Drusberg Nappe consists only of Cretaceous to Paleogene sediments, locally with slices of Late Jurassic limestone (Quinten Formation) at its base.
Deutsch: Mont-Mary-Decke Français: Nappe du Mont Mary Italiano: Falda del Mont Mary English: Mont Mary Nappe
The Mont Mary Nappe is a Salassic tectonic unit constituted by two crystalline basement units: a Lower Unit mainly comprising pre-Alpine amphibolite-facies paragneisses with minor amphibolites and orthogneisses and an Upper Unit comprising pre-Alpine amphibolite- to granulite-facies paragneisses with mafic and carbonate rocks.

The Etirol-Levaz Slice is an Upper Penninic tectonic unit situated between the Zermatt-Saas Fee Nappe and the Tsaté Nappe. It comprises eclogitic micaschists similar to that of the structurally higher Dent Blanche and Sesia nappes. It is likely derived from extensional allochthons, formed during the Jurassic opening of the Piemonte-Liguria Ocean in a more distal position than the Cervinia Terrane from which the Salassic nappes originate.

The Châtillon-St-Vincent Slices are Upper Penninic tectonic units situated between the Zermatt-Saas Fee Nappe and the Tsaté Nappe. They comprise eclogitic continental basement rocks similar to that of the structurally higher Dent Blanche and Sesia nappes. They are likely derived from extensional allochthons, formed during the Jurassic opening of the Piemonte-Liguria Ocean in a more distal position than the Cervinia Terrane from which the Salassic nappes originate.
