IRSL-dating of periglacial slope deposits. - Results from the Bayerische Wa
ld (Bavarian Forest). - 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 colic components (Loess) like the Upper- and Middl
e Head (Haupt-/Mittellagen) are in general datable. As a consequence of pol
ygenetic processes during the genesis of periglacial slope deposits and a f
ollowing soil formation an average age is obtained which doesn't give any i
nformation on the true sediment age. Both underaged and overaged IRSL-data
must be concidered due to pedobioturbation processes. For this reason the I
RSL-data do not give even a maximum age of these types of sediments. Perigl
acial slope deposits generated by solifluction processes are not dateable d
ue to a lack of sufficient lightening of the single grains.
