| Abstract | The transition from the clastic Calais deposits to the main body of the Holland peat in the western Belgian coastal plain was investigated by means of diatom analyses of seven cores, from close to the present coastline up to the polder border. At all sites the peat was found to rest upon mudflat and saltmarsh deposits and not upon lagoonal sediments, as often supposed. Peat formation in the backswamps was apparently induced by the waterlogging of silted-up areas due to a considerable supply of fresh water, mainly of inland origin. |
