p.17: The Naret Formation is surmounted by a uniform alternation of thin layers of calcareous sandstones and quartzic limestones, more calcareous at the base, called here the Massari Formation. It looks similar to the Lower Liassic of several Helvetic units, e.g. in the Morcles and Wildhorn nappes.
