We study the use of zircons as dosimeters using modern techniques, highlighting their advantages such as time-invariant dose rates. We explore the correlation between zircon geochemistry and luminescence properties, observe fast zircon optically stimulated luminescence (OSL) bleaching rates, and assess the potential of auto-regeneration. Low OSL sensitivities require combining natural OSL and auto-regenerated thermoluminescence (TL), with the potential to enhance age accuracy and precision.

We present results of the Baix loess–palaeosol sequence, SE France. Reconstructed intense soil formation under warm, moist conditions before and into the last ice age and less intense soil formations in warm (temporarily moist) phases during the generally cold, dry ice age were validated with laboratory and dating techniques. This is particularly relevant as Baix is located in the temperate–Mediterranean climate transition zone, a sensitive zone that is susceptible to future climate changes.

Here, we present the lighting setting implemented in the new Luminescence Dating Research Laboratory at Stony Brook University, USA. First, we performed spectral measurements on different light sources and filters. Then, we measured the loss of dose in quartz and feldspar samples when exposed to various light sources and durations. Finally, we conclude that our lighting setting is suitable for a luminescence darkroom laboratory; it is simple, inexpensive to build, and durable.

During the last glacial period, cold conditions associated with changes in atmospheric circulation resulted in the deposition of widespread loess. It seems that the phases of loess accumulation were not strictly synchronous. To test this hypothesis, the chronology of loess deposition in different regions of Europe was studied by recalculating 1423 luminescence ages in a database. Our study discusses the link between the main loess sedimentation phases and the maximal advance of glaciers.

The concept of open data has become the modern science meme. Funding bodies and publishers support open data. However, the open data mandate frequently encounters technical obstacles, such as a lack of a suitable data format for data sharing and long-term data preservation. Such issues are often community-specific and demand community-tailored solutions. We propose a new human-readable data format for data exchange and long-term preservation of luminescence data called XLUM.

The R package sandbox is a collection of functions that allow the creation, sampling and analysis of fully virtual sediment sections, like having a virtual twin of real-world deposits. This article introduces the concept, features, and workflows required to use sandbox. It shows how a real-world sediment section can be mapped into the model and subsequently addresses a series of theoretical and practical questions, exploiting the flexibility of the model framework.

Dosimetric dating methods based on the analysis of luminescence signals emitted by granular minerals extracted from sedimentary deposits now play an important role in the study of the Quaternary. Here we propose a new approach in which the age of the deposit is calculated by combining the equivalent dose and dose-rate distributions. The underlying Bayesian mathematical model and its implementation via an R code are provided, together with the results obtained for a finite set of configurations.

Luminescence dating requires irradiating the sample in the laboratory. Here, we address some concerns about the reliability of the calibration procedure that have been published recently. We found that the interplay between geometrical parameters such as grain size and aliquot size impacts the calibration value more than previously thought. The results of our study are robust and allow us to recommend an improved calibration procedure in order to enhance the reliability of the calibration value.

Our contribution enhances the infrared radiofluorescence dating technique, used to determine the last sunlight exposure of potassium feldspars in a range of about 600 to 600 000 years backwards. We recorded radiofluorescence images of fine sands and processed them with tailored open-source software to obtain ages from single grains. Finally, we tested our new method successfully on two natural sediment samples. Studies in Earth science will benefit from improved age accuracy and new insights.

This paper demonstrates how to model optically stimulated luminescence (OSL) and radiocarbon ages in a Bayesian framework, using a dedicated software tool called BayLum. We show the effect of stratigraphic constraints, of modelling the covariance of ages when the same equipment is used for a series of OSL samples, and of including independent ages on a chronological inference. The improvement in chronological resolution is significant.

This study tested the application of single-grain feldspar luminescence for dating and reconstructing sediment dynamics of an extreme mass movement event in the Himalayan mountain range. Our analysis revealed that feldspar signals can be used to estimate the age range of the deposits if the youngest subpopulation from a sample is retrieved. The absence of clear spatial relationships with our bleaching proxies suggests that sediments were transported under extremely limited light exposure.

This study presents the results of an outdoor flume experiment to evaluate the effect of turbidity on the bleaching of fluvially transported sediment. Our main conclusions are that even small amounts of sediment lead to a substantial change in the intensity and frequency distribution of light within the suspension and that flow turbulence is an important prerequisite for bleaching grains during transport.

Chemical weathering alters the chemical composition of mineral grains, and it follows that luminescence dating signals may also be progressively modified. We artificially weathered feldspar samples under different chemical conditions to understand the effect of feldspar partial dissolution on their luminescence properties. Only minor changes were observed on luminescence dating properties, implying that chemical alteration of feldspar surfaces may not affect luminescence dating signals.

Short summary
Mineral grains within sediment or rock absorb a radiation dose from the decay of radionuclides in the host matrix. For the beta dose component, the estimated dose rate must be adjusted for the attenuation of beta particles within the mineral grains. We show here that the mean dose rate to dosimeter grains in a granular matrix is dependent on the grain-size distributions of the source grains, the bulk sediment, and the grain size of the dosimeters.

It is of critical importance to dosimetric dating techniques that the quantity of the radiation dose is estimated accurately. Here we describe gamma spectrometry in terms of instrument, measurement procedures, and data analyses required for estimating parent nuclide activities. The description includes analytical procedures required to generate data with sufficient accuracy and precision for samples in secular equilibrium. We also outline procedures required to quantify disequilibrium.

The µDose system is an innovative analytical instrument developed for the cost- and time-efficient determination of environmental radionuclide concentrations required for the calculation of sedimentation ages in palaeo-environmental and geo-archaeological research. The results of our study suggest that accuracy and precision of µDose measurements are comparable to those of well-established methods and that the new approach shows the potential to become a standard tool in environmental dosimetry.

We apply new rock luminescence techniques to a well-constrained scenario of the Beinn Alligin rock avalanche, NW Scotland. We measure accurate erosion rates consistent with independently derived rates and reveal a transient state of erosion over the last ~4000 years in the wet, temperate climate of NW Scotland. This study shows that the new luminescence erosion-meter has huge potential for inferring erosion rates on sub-millennial scales, which is currently impossible with existing techniques.

Short summary
Luminescence properties of samples from the Rinikerfeld, northern Switzerland, are assessed. Reader-specific low preheat temperatures are invesigated to ensure suitable measurement conditions. While quartz is found to be dominated by stable fast components, signal loss is observed for feldspar and polymineral. In general, the ages of the fading corrected feldspar and the fine-grained polymineral fractions are in agreement with coarse-grained quartz, and ages indicate sedimentation during MIS6.

Short summary
Optically stimulated luminescence dates the last exposure of quartz and feldspar minerals to sunlight. We investigated its sub-methods (TT-OSL, VSL, and pIRIR) to date middle and early Pleistocene sediments. Inspection of natural signals of samples can reveal saturated samples that produce only minimum ages. Using these sub-methods, minimum ages of up to the early Pleistocene can be obtained for eastern Mediterranean aeolian sediments of Nilotic origin.

Short summary
This is a preliminary study using a synchrotron light source to generate elemental maps, incorporating oxidation states, with a spatial resolution of <1 µm for individual grains within the K-feldspar density fraction. The elemental fingerprint characterizing grains with a signal suitable for infrared radiofluorescence dating reveals high levels of K, Pb, and Ba coupled with low levels of Fe and Ca. In contrast, grains exhibiting higher proportions of Fe and Ca produce an odd signal shape.
