    In short

    The Berisal Nappe is a Middle Penninic tectonic unit occupying the core of the large synformal Berisal Backfold. It consists of a polycyclic basement with numerous pre-Alpine relics. It is thus lithologically similar to the Upper Stalden Nappe and interpreted as the continuation of this unit to the east, in the footwall of the Rhône-Simplon Fault.
