Abstract
Within the context of the western Paris Basin, considered to be a region experiencing slight uplift during Neogene and Quaternary, the ESR dating of Quaternary deposits, together with those of Neogene age, the morphology and available geophysical data suggest that the Somme valley is an actively subsiding sector (tectonic shortening between two active inversions). The dissymmetry of the valley tributaries and of the deposits preservation is controlled by a flexuring above the hidden Somme fault. The record of neotectonic events and the geophysical data demonstrate its activity and elucidate the recent history of the Paris Basin.
