Abstract:

The optically stimulated luminescence (OSL) dating of quartz is widely used to
establish an absolute chronology for sedimentary deposits. However, its appli-
cability is in general limited to the last ~ 150 ka. Therefore extending the range
of quartz luminescence dating beyond this limitation is a key challenge. In this
talk, I will present our attempts to develop and test the applicability of other
luminescence signals from quartz to extend the age range of conventional OSL
dating to cover the full Quaternary.
