Die IRSL-datierung von periglazialen Hangsedimenten-Ergebnisse aus dem Bayerischen Wald

Infrared-Stimulated-Luminescence (IRSL) is somewhat suitable for dating periglacial slope deposits. Those slope deposits which have been strongly influenced by cryoturbation and have a high content on syngenetically delivered eolic components (Loess) like the Upper- and Middle Head (Haupt-/Mittellagen) are in general datable. As a consequence of polygenetic processes during the genesis of periglacial slope deposits and a following soil formation an average age is obtained which doesn't give any information on the true sediment age. Both underaged and overaged IRSL-data must be concidered due to pedobioturbation processes. For this reason the IRSL-data do not give even a maximum age of these types of sediments. Periglacial slope deposits generated by solifluction processes are not dateable due to a lack of sufficient lightening of the single grains.
