“…Up until now, the estimation of an equivalent dose (DE) using the thermoluminescence (TL) signal is performed mainly by multiple-aliquot additive dose (MAAD) protocols. However, the MAAD approach shows numerous disadvantages, which are mainly associated with the large quantity of the datable material needed to obtain a DE estimate, the lack of validation tests (e.g., dose recovery tests [1]), and complications in appropriately extrapolating a derived TL growth curve to the dose axis, as well as the difficulty of reproducing the derived TL signals of a given laboratory dose.…”

Establishing the absolute age of palaeoearthquakes is of great significance for the assessment of the seismicity and seismic hazards of a region. As such, several different geochronological techniques to date earthquake-related material have been developed to provide answers on the time of past earthquakes. The present study is part of a wider palaeoseismic research project conducted in the Nojima Fault Zone (NFZ), where the 1995 Mw 6.9 Kobe (Japan) earthquake was triggered, to assess the suitability of the isothermal thermoluminescence (ITL) dating technique on fine-grained quartz and medium-grained feldspar and to provide a sequence of ages for fault-rock samples separated from a drilled core that was retrieved from a depth of ~506 m. Our analysis reveals that ITL can produce consistent dating results and can be considered a reliable luminescence technique for the absolute dating of fault-gouge material. The produced ITL ages signified the existence of repeated seismic events within the NFZ that took place through the late Pleistocene period, with gouge ages spanning from 78.6 ± 4.2 to 13.4 ± 1.4 ka; however, overestimation of the produced ITL dating results may be apparent. Nonetheless, even though some degree of overestimation is considered, ITL dating results denote the oldest possible age boundary of formation (or luminescence signal resetting) of the collected fault-gouge layers.

Thermoluminescence (TL) dating is now widely used in the age determination of Paleolithic sites. Although the basic principle of TL-dating is simple, the underlying assumptions are not trivial. One major source of error is the external dose rate, which contributes to a varying degree to the denominator of the age formula and thus has a varying influence on the dating result. The intention of this paper is to enable the user to evaluate TL age determinations of heated flint. The parameters used for age determination and some of their relationships are discussed. It is shown that the reliability of TL results of heated flint depends on the proportion of the various dose-rate parameters and that these are important for the evaluation of ages. The limitations of the method as well as the advantages are discussed. TL-dating results for two Near Eastern Paleolithic sites (Rosh Ein Mor and Jerf al-Ajla) are discussed as examples.
