Untere Mittelterrasse und Krefelder Mittelterrasse im Südteil der Niederrheinischen Bucht

Klaus-P. Winter
The area of the Lower Middle-Terrace (Untere Mittelterrasse) and the Krefeld Middle-Terrace (Krefelder Mittelterrasse) in the southern part of the Lower Rhine Vallay has been restudied. Results: In the western part of Köln the morphological division of these terraces is not due to fluvial accumulation but dependent on the different thickness of overlaying deposits (loess). The Lower Middle-Terrace covers the whole vallay step. The Krefeld Middle-Terrace is not developed.
