“…Likewise other studies (e.g. Ganzawa et al, 2005), the observed sensitivity changes of R-TL were always smaller than the generally accepted 10% threshold and R-TL growth curves do not show large deviations from linear growth for most samples (data to be published elsewhere). D E -values obtained for standard and 'short' SAR protocols are identical (at 1σ) with similar precision and dose recovery tests were also equally satisfying (<10% deviation from unity).…”

Palaeodose Underestimation Of Heated Quartz In Red-TL Dating Of Volcanic Contexts

Thermoluminescence (TL) dating is a valuable tool for chronometric dating of heated minerals and has been shown to agree very well with independent age control. Comparison with argon dating of samples from identical events, however, revealed age underestimations of volcanic eruptions dated by orange-red TL (R-TL) of quartz extracts from some xenolith samples, while good agreement was obtained for others. The underestimation is attributed to an apparent signal loss ("anomalous fading") which was experimentally observed for some, but not all samples investigated. The presence of significant amounts of feldspar or tridymite, which could be related to the observations, is excluded by IRSL (Infrared Stimulated Luminescence) and XRD analysis. While the data is not entirely conclusive, it leads to the current working hypothesis that exposure to high temperatures might be responsible for an effect similar to the anomalous fading phenomena observed for some feldspar luminescence. It therefore appears to be prudent not to sample xenoliths from high temperature context, like basalt dykes in volcanic context.

“…For detrital quartz, as well as for primary volcanic quartz, the dating has been generally done using red TL (RTL). For volcanic quartz (Hashimoto et al, 1987(Hashimoto et al, , 1991(Hashimoto et al, , 1996Fattahi and Stokes, 2000;Stokes and Fattahi, 2003;Ganzawa et al, 2005) the estimated ages agreed with geological expectations. These results provided initial evidence of the suitability of volcanic quartz for TL dating, but they represent a limited data set that has not been tested by other dating methods.…”

Proposing new approaches for dating young volcanic eruptions by luminescence methods

et al. 2011

Abstract:The application of luminescence dating to young volcanic sediments has been first investigated over three decades ago, but it was only with the technical innovations of the last decade that such analyses became viable. While current analytical procedures show promise for dating late Quaternary volcanic events, most efforts have been aimed at unconsolidated volcanic tephra. Investigations into direct dating of lava flows or of non-heated volcanoclastics like phreatic explosion layers, however, remain scarce. These volcanic deposits are of common occurrence and represent important chrono-and volcanostratigraphic markers. Their age determination is therefore of great importance in volcanologic, tectonic, geomorphological and climate studies. In this article, we propose the use of phreatic explosion deposits and xenolithic inclusions in lava flows as target materials for luminescence dating applications. The main focus is on the crucial criterion whether it is probable that such materials experience complete luminescence signal resetting during the volcanic event to be dated. This is argued based on the findings from existing literature, model calculations and laboratory tests.
