La mer de la manche, modèle de bassin sédimentaire épicontinental sous climat tempéré

Abstract : The English Channel is a shallow epicontinental basin characterized by a slow litho - bioclastic sedimentation established since Flandrian transgression. For the main part, terrigenous material is old whereas bioclasts, Flandrian for age, are progressively contaminating the siliceous deposits. The sediments distribution is controlled by tidal currents and the deposits are arranged in horizontal lithoclastic and bio-lithoclastic sedimentary sequences. The waves interfere efficaciouslyin coastal areas only. Actually, the deposits repartition takes place in a Flandrian model which evolves slowly by enrichment in bioclastic material.
