National audienceThe plio-pleistocene period which covers a geological long time is assimilated by few authors at the villafranchian period. It is situated at the boundary between Pliocene and early Pleistocene. It is characterized by alluvial thick formations (ranas) with blocks and big pebbles, by ferralitic grounds, weathering of cristalline rocks and old thick calcareous crusts (Moulouyen). These pedologic formations show climatic changes between upper Tertiary and early Quaternary. All the plio-villafranchian formations are situated above the quaternay alluvial and colluvial levels. The topography and drainage patterns are different between plio-villafranchian and quaternary period. Finally, these dposits are deformed by villafranchian...
