Current research is focused on assessing the maximum achievable precision of luminescence
ages of sedimentary quartz. High-resolution luminescence chronologies are constructed for
sedimentary deposits that archive the paleoclimatic changes during the Quaternary. The
problem resides in the incorporation of luminescence ages in age-depth-models which is limited
to this date due to the complexity of the uncertainty estimation system involved in age
evaluation which is not fully standardized yet. This problem is approached by conducting a
thorough empirical assessment in error limit assessment by field and laboratory studies of
coeval known age samples, and observing the degree of precision and accuracy that can be
achieved by luminescence dating. The final aim is the improvement of age modeling studies of
luminescence-dated paleoclimate archives, especially loess deposits and an informed and
correct incorporation of luminescence ages into age-depth models, thus increasing their
robustness and accuracy.
