Quaternary formations from the sub-pyrenean region get their origin from the reworking of former detritic deposits of the substratum. Two kinds of quaternary surface deposits are investigated. 1° Unknown red loams, occupate the upper part of long valleyside of Magnoac region. They may be attribuated to the Middle Quaternary. 2° Some « Boulbènes », local name given to pedologic profile, classified among the « sols lessivés podzoliques », occupy the lower part of the valley sides. These soils have been made during Quaternary, as often as a certain kind of propicious conditions occured together : particularly, local hydromorphic conditions.Les terrains quaternaires de cette région sous-pyrénéenne ont pour origine le remaniement de dépôts détri...
