The rest of this domain (the Dent Blanche klippe and Sesia zone) formed the former back-stop of the Tsaté accretionary prism and was partly overthrusted by the Adriatic micro-continent (South Alpine units). The Molasse deposits started in Late Oligocene and lasted until Late Miocene and are made of shallow water marine or continental deposits. rim basin, rift shoulder, passive margin, oceanic sequences, inversion basin, flexural bulge). Italian topographic maps clearly show the France-Italy border passing over the summit of Mont Blanc, as specified by treaty. Those crystalline massifs represent the Variscan basement of the northern fringe of the orogen. It is characterised by typical thin skin tectonic with a décollement located in Triassic evaporitic deposits. Ao = Adamello intrusions; DB = Dent Blanche nappe; Go = Gotthard massif; GP = Grand Paradis massif; LE = Lower Engadine window; MB = Mont Blanc massif; MR = Monte Rosa nappe; Pr = Provence basin; TW = Tauern window; VVL = Villalvernia-Varzi-Levanto line.

The eclogitic internal massif (Mont Rose, Gran Paradiso, Dora Maira) are continental exotic blocks of disputed origin (lower Austroalpine, Briançonnais or even Helvetic e.g. They are from north to south: This is the most external domain, incorporated in the Alpine chain last (from 11 to 3 Ma). Translations of the phrase WESTERN ALPS from english to spanish and examples of the use of "WESTERN ALPS" in a sentence with their translations: ...jura and the central and western alps . Savoie), the whole of Monaco, the northwestern part of Italy and the southwestern part of Switzerland (i.e. parts of the Internal Massifs). In the more internal part of the middle Penninic units are found the Mont-Fort nappe (located in the Valais) and Brèche nappe (located in the Préalpes), representing the former syn-rift part of the European margin on the Briançonnais transect. These nappes are found in several locations: first as a sole of the Préalpes massif; as klippen on the Helvetic nappes and in the Helvetic root zone. Denuded continental mantle units like the Geisspfad massifs represent this transition found within the lower Penninic nappes named Valaisan domain in the paleogeographic nomenclature. Perhaps the most famous tram ride in the world terminates at the Aiguille du Midi, in the middle of the glacial splendor of the Mont Blanc massif (1996-03-12). Les Noisettes is a traditional Haute Savoie chalet. These mainly crustal nappes in western Switzerland represent the former southern passive margin of the Alpine Tethys. The Lias-Dogger sequence is influenced by crustal extension which resulted in the formation of the Helvetic rim-basin to the north of the Piemont rift shoulder. A bike tour of the Alps with its Tour de France and Giro d'Italia climbs is a dream come true for any serious rider. The Late Jurassic and Cretaceous sequence is marked by the progradation of a carbonate platform which never succeeded filling-up the Wildhorn basin and never reached the distal rifted Helvetic margin. This domain represents the northern margin of the Adriatic microplate, its northeastern part (Canavese) collided with the displaced Austroalpine elements during their westward escape in Late Cretaceous.

This area was a high during the Alpine Tethys rifting as a consequence of unloading to the south in the Helvetic rim basin. Valais). Towering over the Cottian Alps is Mount Viso, monarch of the Western Italian Alps, a majestic and isolated pyramid that, on a clear day, can be seen from almost the entire Piedmont region.
