- This work focuses on fossil organic carbon (FOC) fluxes due to chemical and mechanical weathering of marls in 2 experimental watersheds with typical badlands geomorphology (Draix watersheds, Laval and Moulin, Alpes de Haute Provence, France
- ). A classical geochemical analysis (Rock-Eval 6 pyrolysis) was used to characterize organic matter in the studied samples (bedrocks, soil litters and riverine particles). FOC fluxes were estimated by monitoring the particulate (1985-2005 period) and dissolved
- (year 2002) exports at the outlet of the watersheds. Results show that FOC delivery is mainly driven by mechanical weathering. These high FOC fluxes from badlands are similar to those observed in tectonically active mountain catchments. At a global scale
