“…The first two quartz samples (Sample 565 rkm and 491 rkm) have practically an identical luminescence sensitivity (154±19 and 159±19 cts/mg/Gy). These values fit well to the mean luminescence sensitivity value of five Pleistocene age sediment samples (167±9 cts/mg/Gy) collected from various points on the alluvial fan of the river and investigated by Bartyik et al (2021). Based on this, it could be expected that there is no significant variation in CW-OSL sensitivity values along the river.…”

“…As luminescence sensitivity is a sample dependent property, thus it has a unique potential in sediment tracing (Gray et al, 2019). This is especially true for quartz, since it can exhibit highly variable sensitivity values, as shown by the study of Bartyik et al (2021).…”

To understand the functioning of fluvial systems it is important to investigate dynamics of sediment transport and the source of sediments. In case of reconstructing past processes these studies must be accompanied by the numerical dating of sediment samples. In this respect optically stimulated luminescence is a widely used technique, by which the time of sediment deposition can be directly dated. Recently, in various fluvial environments it has been shown that certain luminescence properties of minerals, and especially that of quartz, can be applied as indicators of fluvial erosion and/or sediment provenance. These properties are residual luminescence (or residual dose) and luminescence sensitivity of quartz grains. However, the values of the parameters above are affected by various factors, the importance of which is under debate. The present study therefore aims to assess these factors along a ~560 km long reach of River Mureş (Maros) a relatively large river with a compound surface lithology on its catchment. The research focused on the sandy fraction of modern sediments, collected from the main river and from three tributaries alike. This way not only longitudinal downstream changes, but the influence of tributaries could also be studied. Based on the data, both investigated parameters show a great variation, which can be attributed to the lithological differences of subcatchments and geomorphological drivers, such as erosional activity and potential number of sedimentary cycles, and human activity. However, relationships are not entirely clear and are influenced by the maximum grain size of the samples investigated, and the recycling of previously laid deposits with different properties. Still, when performing detailed dating studies, and tracing sediments from certain parts of the catchment luminescence properties can be a useful tool in the future.

“…Throughout the measurements, the single aliquot regeneration (SAR) protocol was applied (Murray and Wintle, 2003; Wintle and Murray, 2006). Prior to SAR tests, some of the samples were subjected to an LM-OSL analysis to resolve the components of the OSL signal and to determine the ratio of the fast component (Bulur, 1996; Jain et al, 2003; Singarayer and Bailey, 2003), that is usually low in Danube sediments (Bartyik et al, 2021). Subsequently, preheat and dose recovery tests were performed to identify the optimal measurement parameters and assess the reproducibility of measurements.…”

The Deliblato Sands is among the largest uniform dune fields of Europe, with a very pronounced topography reflecting extensive past aeolian events. Although lacking numerical age data, previous researchers have hypothesized various periods of dune formation. Our research goals were to map the main morphological units of the Deliblato Sands, and to provide the first optically stimulated luminescence (OSL) ages for the major dune types. Mapping was carried out using digital elevation models, satellite images, and GPS profiles. Dune development was investigated using OSL. Several tests were performed concerning thermal treatment, signal characteristics, dose recovery, and dose distributions to assess the suitability of sediments for luminescence dating. Based on our results, two dune generations could be identified that differed in morphology and age. Older dune forms are primarily low sand-supply, hairpin-like parabolic dunes that developed from the last glacial maximum until the end of the early Holocene, then became stabilized. Younger, superimposed parabolic dunes record an intensive aeolian signal from the eighteenth and nineteenth centuries. The history of the Deliblato Sands fits with those from other European sand dune areas, and provides further details to understand paleoenvironmental changes in the region.

“…Firstly by the increased contribution of catchments rich in low sensitivity quartz to the sediment mixture of the palaeochannel. For example, it was demonstrated by Bartyik et al (2021b) that the quartz sensitivity in a major tributary of the Maros/Mureş (River Strei), collecting the sediments of the Northern and Southern slopes of the Retezat Mts., is lower than the sensitivity of quartz from other catchments. Consequently, after the deglaciation this catchment could provide a considerable input to the main river.…”

River Maros/Mureş has one of the largest alluvial fans in the Carpathian Basin. On the surface of the fan several very wide, braided channels can be identified, resembling increased discharges during the Late Glacial. In our study we investigated the activity period of the largest channel of them, formed under a bankfull discharge three times higher than present day values. Previous investigations dated the formation of the palaeochannel to the very end of the Pleistocene by dating a point bar series upstream of the selected site. Our aim was to obtain further data on the activity period of the channel and to investigate temporal relationships between maximum palaeodischarges, deglaciation phases on the upland catchment and climatic amelioration during the Late Pleistocene. The age of sediment samples was determined by optically stimulated luminescence (OSL). The investigation of the luminescence properties of the quartz extracts also enabled the assessment of sediment delivery dynamics in comparison to other palaeochannels on the alluvial fan. OSL age results suggest that the activity of the channel is roughly coincident with, but slightly older than the previously determined ages, meaning that the main channel forming period started at 13.50±0.94 ka and must have ended by 8.64±0.82 ka. This period cannot directly be related to the major phases of glacier retreat on the upland catchments, and in terms of other high discharge channels only the activity of one overlaps with a major deglaciation phase at ~17-18 ka. Based on these, high palaeodischarges can be rather related to increased Late Glacial runoff, resulted by increasing precipitation and scarce vegetation cover on the catchment. Meanwhile, the quartz luminescence sensitivity of the investigated channel refers to fast sediment delivery from upland subcatchments. Therefore, the retreat of glaciers could affect alluvial processes on the lowland by increasing sediment availability, which contributed to the development of large braided palaeochannels.
