Übertiefte Rinnen im Hamburger Raum

Friedrich Grube
Geomorphological and geological studies of overdeepened valleys were focused in the western, northern and central parts of the Hamburg area. During the Elster glaciation valleys up to —400 m NN were eroded by subglacial processes in the tertiary basal plane. They contain coarse glacifluvial sands and glacilacustrine silt and clay. These valleys, therefore, were protected during the ingression of the Holstein sea. Several shallower valleys up to —60 m NN were filled with tills and...
