Structures périglaciaires syngénétiques dans quelques terrasses fluviatiles du Nord de la France et en Belgique

The author presents a detailed description of pillar-channels characteristic for the sedimentary structure of some pleistocene terraces. He puts forward a genetic interpretation, stresses their value as an indicator for the fluvio-periglacial nature of the terrace deposit and questions their stratigraphic meaning. He presents a more accurate definition of some terrace-levels in the southern part of the pleistocene Scheldt basin.
