Resumo:  The southern Biscay shelf is a typical example of a continental margin submitted to a macrotidal regime and the heavy sedimentary fluxes of continental provenance. The aim of this study was to determine the manner in which clay sedimentation is organized on the margin and to evaluate the impact of both river-borne inputs and marine hydrodynamic activity. It was established that the distribution of clay minerals (in the order of frequence: micas, chlorites, illites and smectites) is upset by the interconnection of several sedimentary processes: discontinuous river-borne discharges (richer in smectites); the mixture of newly-arrived material with fine fractions (rich in micas and chlorites) resulting from the reworking of remnant material that represents the major part of the sea-floor and the ultimate stockage occurring at depths greater than 50 m. It appears that physical processes control to a large extent the distribution of clay phases.
