Geological materials used for luminescence dating and associated with the fall of meteorites on the Earth’s surface are extremely rare. The Morasko region has gained fame over the past 100 years because of a cosmic catastrophe which took place there. After thousands of years, the remains of a large metal meteorite which fell in this area have been found. In this article, we would like to state whether it is possible, using luminescence methods, to determine the moment when the iron meteorite fell on the surface of the Earth. The material which was analysed consisted of meteorite crust layers – melt/fusion and “semi melt/fusion”, including sintered ones, along with the sediments surrounding the meteorite. The final results are connected with four objects of different sizes (large ones and small shrapnel – 261 kg, 34 kg, 970 g and 690 g). The obtained results show a large discrepancy, which is most likely associated with the problem of resetting the luminescence signal of the tested materials.

“…Al Khasawneh et al . () demonstrated valid dose‐recovery tests for both optical and thermal resetting methods applied to ceramics and heated stones from Denmark. The present study obtained a mean measured to given dose ratio of 0.97 ± 0.04 for the samples from the kiln, if the reset occurred thermally, demonstrating that the pIRIR 290 protocol can measure a known laboratory dose if the natural signal is reset by a temperature treatment comparable with the initial signal reset.…”

Roman traces in Germania magna: New thermoluminescence and pIRIR₂₉₀ data from a lime kiln at Bergisch Gladbach, Germany

The applicability of a post-infrared infrared stimulated luminescence (pIRIR 290 ) protocol and two different thermoluminescence (TL) protocols-a single aliquot regeneration (SAR) and a multiple aliquot additive dose (MAAD)-was tested on six polymineral fine-grain (4-11 μm) samples extracted from the wall remains of a Roman lime kiln and a Roman roof tile. These remains had been excavated close to Bergisch Gladbach, which was at that time part of Germania magna. For the pIRIR 290 measurements, no dependence of D e on first-stimulation temperature was detectable, and the standard first stimulation temperature at 50°C was adopted. Fading tests and dose-recovery tests were made for all samples. Background subtracted glow curves were recorded up to 480°C for TL after a preheat of 220°C for 120 s. A-values were determined for all TL and pIRIR measurements. The results for all three protocols were fairly consistent, and TL and pIRIR 290 protocols are shown to be suitable to estimate reliable equivalent doses for the fired kiln walls. The resulting ages are in agreement with the expected time range-Roman Iron Age-and with independent age control provided by radiocarbon ages of animal bones and charcoal from the firing chamber. Highlights: A Roman lime kiln and surrounding sediments were successfully dated using both thermoluminescence (TL) and post-infrared infrared stimulated luminescence (pIRIR).

“…Auclair et al,(2003) and Huntley and Lamothe (2001). Despite the identification of much more stable IR signals from feldspar, few if any studies have tested their application to ceramics (al Khasawneh et al, 2015). Even young heated materials should be well suited to pIRIR protocols, because the high temperature firing should completely empty any IR-sensitive trapped charge Thomsen et al, 2011) and eliminate the possibility of thermal transferred signals (Ollerhead et al, 1994); these often limit the applicability to young unheated materials because of the resulting apparent large residual dose, even in well-bleached sediments (Reimann et al, 2011(Reimann et al, , 2012.…”

Recent developments in the use of more stable feldspar signals in the luminescence dating of sediments offer the possibility of obtaining accurate feldspar luminescence ages for ceramic artefacts; this is especially interesting in locations which do not provide suitable quartz extracts. Here we examine the application of the stable infrared stimulated luminescence signal measured at elevated temperature (in this case 290°C; pIRIR 290 ) after stimulation at about room temperature to Levantine pottery samples. A total of 52 potsherds were collected from three superimposed iron-age units at Pella (Jordan); based on 14 C dating, typology and seriation these units were deposited between 700 and 900 BCE. Sand-sized quartz extracts were unsuitable, and there was insufficient sand-sized feldspar, and so polymineral fine grains were chosen for dating. Various tests for reliability were undertaken (dose recovery, dependence of D e on first stimulation temperature etc.). The pIRIR signals are weak, and 14 potsherds were rejected on this basis. Of the remainder, 3 were confidently identified as outliers. Based on those sherds for which IR signals were sufficiently intense, we use the ratio of the IR 50 to pIRIR 290 signals to argue that these outliers do not arise from incomplete resetting during manufacture. The ages from each layer are considerably over dispersed (typically by ~25%) but average ages for each unit are consistent with each other and with the expected age range. The average OSL age for the site is 2840 ± 220 years (n = 35), with the overall uncertainty dominated by systematic uncertainties; this average is consistent with the range of 14 C ages from 970-1270 BCE reported from across the destruction horizon. We conclude that the pIRIR 290 signal is delivering accurate ages, but that the variability in age from shard to shard is much greater than would be expected from known sources of uncertainty. This demonstrates the need for site ages to be based on multiple samples; individual shard ages are unlikely to be sufficiently accurate.
