Similar as for partial optical bleaching of the TL of sediments, the ratio of resetting during partial heating referred to the natural TL is glow temperature-dependent. By replacing laboratory optical bleaching using incremental bleach times with laboratory partial heating using incremental temperatures as shown for the PHLP technique, the correct DE accumulated since the eruption may be expected. The validity of this approach has, however, to be tested in laboratory experiments which, to our knowledge, have not been tried so far. The present study may open new perspectives for TL dating of Middle and Upper Quaternary volcanic events by the evolution of a complementary physics-based dating method applicable to a wide range of materials and eruption types. We thank Dipl-Inf. FH Manfred Fischer for support during laboratory work in the luminescence dating laboratory at the University of Bayreuth, Dr.

Abstract Half a century after the publication of the first Thermoluminescence TL ages, the field of Luminescence Dating has reached a level of maturity. Both research and applications from all fields of archaeological science, from archaeological materials to anthropology and geoarchaeology, now routinely employ luminescence dating. The advent of optically stimulated luminescence OSL techniques and the potential for exploring a spectrum from mono-minerallic single grains to polymineral multi-aliquots enhanced the applicability, accuracy and the precision of luminescence dating. The present contribution reviews the physical basis, mechanisms and methodological aspects of luminescence dating; discusses advances in instrumentations and facilities, improvements in analytical procedures, and statistical treatment of data along with some examples of applications across continents.

The partial heat — longest plateau technique: Here, we present first tests of a newly developed technique to use the thermoluminescence TL of maar tephra and crustal xenoliths for dating the eruption event. We take into consideration that resetting of the latent geological TL of country rock fragments during eruption may be incomplete. This technique can overcome TL age overestimates due to incomplete zeroing, as is demonstrated for some eruptions in the Quaternary Eifel Volcanic Field, Germany, in the time range from 11 to ka old.
