Mikromorphologie und Genese von Böden auf den Niederterrassen des Niederrheingebietes und der Kölner Bucht

Siegfried Stephan
Dated soils of different age from the lower Rhine terrasse are characterized by micromorphology, and selected features are set against the soil age. There are clear relations between soil forming advancement and decalcification as well as clay migration. Some development is already visible in the 1800 year old soils. After 6000 years, Parabraunerden (Orthic Luvisols) appeare. Soils on Preholo-cene sediments are strongly developed Parabraunerden, often suffered by Fe-Mn redistribution. The weathering of silicates started in...
