Crystalline, volcanic and sediment annoyances in the main and middle terrace deposits of the Rhine west of Krefeld
Description
N the main terrace deposits of the Rhine, spread between the Süchtelner Höhenzug and Viersen-Boisheim, were repeatedly found during the past years during site inspections of crystalline, vulcanite and sedimentary rocks. They confirm previous finds made since the beginning of the 20th century in various places in this region. The deposits of the Kristallingesteine are located in some cases more than 20 km from the Saale Age ice rim, which stretched between Krefeld and Nijmegen (Netherlands) over a length of about 70 km and is today characterised by some mighty moraine moraines and their sanders. Due to their great distance from the edge of the moraines, e.g. the Schaephuysen mountain range, the crystal stones can therefore hardly be regarded as glacifluviatile relics of a Saalian sander. ...For the vulcanite and sediment annoyances as well as for a large part of the crystal stones detected in the main terraces, however, only a southern origin from the catchment area of the Rhine is considered. ...
