【 摘 要 】

A geomorphological and sedimentological analysis makes it possible to identify the different Quaternary formations in the Orbieu valley. Then, the reconstruction of the longitudinal and transversal profiles shows the evolution of tectonic deformations since the formation settling. Neotectonics have been active up to the accumulation of the alluvial deposits of the Weichselian lower terrace. The dating of the Graffan travertines would allow adjust the Orbieu terraces system chronology.
