By means of pedostratigraphy it is possible to establish cycles of cold and warm periods within the Quaternary at many sites in Central Europe and to correlate them even over long distances. TL dating was carried out for samples from several outcrops of loess-paleosol sequences to improve the correlation of the pedostratigraphy. A special loess dating technique (pre-annealing all sample aliquots at 260°C for 1 min., use of a blue-translucent Corning® 5–58 filter) was developed to obtain TL ages up to 0.3 Ma, a period which covers three cold and two interglacial phases. The stratigraphy of the North European glaciations can be improved by TL dating. the Saalian is subdivided into the Older Saalian Glaciation (300-230 ka ), an interglacial period (Treenian, 230-190 ka ), and the Warthian Glaciation (190−128 ka). In the Rhine area, the “Kärlich Interglacial” has to be placed in between the Holsteinian and the Eemian interglacials according to its pollen diagram and its stratigraphic position. At the Kärlich site, the underlying and overlying loesses were dated to 230 and 152 ka, respectively. According to the TL ages of the loesses, the latest two interglacial paleosols can be correlated with the warm stages 5 and 7 of the Oxygen Isotope Curve of deep-sea cores. The Kärlich Interglacial corresponds to stage 7.
