p.33: The Aiguilles Rouges Massif is separated from the Mont Blanc Massif by a thin band of Mesozoic sediments often referred to as the “Chamonix Syncline” in the literature. Most of these sediments can be considered as belonging to the cover of the Mont Blanc Massif, although its basal contact is strongly tectonized, even tectonic (Pfiffner et al. 2010). This band hides important tectonic contacts, not only that between both massifs and their sedimentary cover, but also a probable SW extension of the Rhône-Simplon Fault (Mancktelow 1992, Hubbard & Mancktelow 1992, Egl i & Mancktelow 2013).
