    From a geological point of view, the Prealps encompass Penninic nappes occuring as klippen resting in front or on top of the Helvetic nappes and which experienced a tectono-metamorphic history distinct from that of the Penninic units located further south in the internal part of the Alps. They consist of sedimentary rocks, originating from regions located further south than the European continental margin.
