p.35: The Chaines Subalpines Nappe is constituted by a Jurassic–Cenozoic sedimentary series affected by a succession of large folds with NW vergence to the north of the latitude of Annecy and with W vergence to the south. Its eastern contact is a thrust fault plunging NW over the Aiguilles Rouges and Belledonne massifs. It is overlain to the north by the Pillon Mélange Zone just below the Penninic Prealps, and overlies the southern end of the Subalpine Molasse to the west. The Chaines Subalpines Nappe is subdivided into several units by thrust faults. All these units are composed of Jurassic–Cenozoic sediments of North Helvetic origin, except the most external one, located south of Annecy, whose series is similar to that of the Internal Folded Jura. As is the case with the Upper Helvetic Drusberg and Säntis nappes further east, the Chaines Subalpines Nappe forms a broad synform, south of the Arve Valley, in the core of which klippen of the Pillon Mélange Zone and the Middle Penninic Préalpes Médianes Nappe are preserved.
