Description :
This paper deals with a geochemical investigation (Rock-Eval pyrolysis) of soil organic matter sampled in a lake watershed, and the study of the sedimentary organic matter trapped in the lake deposits. The research was conducted on Chaillexon Lake which was created by a rock collapse that dammed the paleovalley of the Doubs River about 12 000 years ago. Since this event, the sediment trap provides a continuous palaeoclimatic record for the Postglacial period. In conclusion, the story of the Chaillexon lacustrine system seems to be marked by a rather sudden soil and forest development at the Preboreal-Boreal transition (9000 BP)
