Observations on the formation and stratigraphic position of the Niederrhein Main Terrace Formation in the area of the Süchtelner Höhenzug and the Schwalm-Nette area
Description
In the area of the Süchtelner mountain range between Herongen and Viersen as well as in the western bordering Schwalm-Nette area, the quaternary strata consists mainly of the 2.6 – 0.5 million years old under- to mid-pleistocene deposits. They belong to the Niederrhein main terrace formation of the Rhein-Maas system. Between the two deposit areas of Rhine and Maas runs the Viersener Sprung, which separates the Krefeld Scholle (Hochscholle) to the east from the Venloer Scholle (deep cholle) in the west. Due to the different tectonic movements, not only the altitude is different, but the width of the terrace sequences also varies greatly between the two areas. Powerful profiles on the Venloer Scholle face slightly powerful profiles on the Krefeld plaice, which are difficult to parallel with each other. Investigations of debris stock, heavy minerals and the number of flints in outcrops and drill profiles provided new insights. In the Schwalm-Nette area, there is a more or less complete sequence of the Niederrhein-Hauptterrassen formation from the elders to the younger main terraces. In addition, the sands and Kiese present in the plateau area of the Süchtelner Höhenzug at the altitude of + 80 to + 85 m NHN are to be classified as deposits of the Tegelen layers.
