Short summary
This study examines the evolution of the lower Bruche River valley in north-eastern France through its fluvial terraces, reflecting past river dynamics and environmental changes. Terrace formations are dated using luminescence to ~ 12–14 ka, ~ 27–35 ka, and at least 200 ka. Methodological improvements over conventional luminescence dating techniques are also discussed and refined in this study.

Previous reconstructions conclude that the southern Black Forest, south-west Germany, temporarily hosted four ice caps during the Late Pleistocene (129 000–11 700 years before present). This work reviews existing studies on glacial landforms north-east of its highest summit, Feldberg (1493 m above sea level), in the light of new observations. Whilst this study largely confirms previous work, we reject and newly describe several glacial landforms.

The Mühlbach series has been given as evidence for a Late Pliocene/Early Pleistocene Aare–Rhine fluvial system in northern Switzerland and southwest Germany. We show that these deposits represent a variety of different units. At the type location, luminescence dating indicates an age of 55 ka, and we interpret the deposits as slope reworking. Beside methodological implications, our studies recommend caution regarding the interpretation of stratigraphic units for which limited data are available.

The Tannwald Basin, explored by drilling and formed by repeated advances of the Rhine Glacier, reveals key geological insights. Ice-contact sediments and evidence of deformation highlight gravitational and glaciotectonic processes. ICDP DOVE 5068_1_C core data define lithofacies associations, reflecting basin infill cycles, marking at least three distinct glacial advances. Integrating these findings aids understanding the broader glacial evolution of the Lake Constance amphitheater.

The loess sequence of Köndringen, Upper Rhine Graben, comprises several glacial–interglacial cycles. It has been investigated using a multi-method approach including the measurement of colour, grain size, organic matter, and carbonate content. The analyses reveal that the sequence comprises several fossil soils and layers of reworked soil material. According to luminescence dating, it reaches back more than 500 000 years.

Erosion processes below glacier ice have carved large and deep basins in the landscapes surrounding mountain ranges as well as polar regions. With our comparison, we show that these two groups of basins are very similar in their shapes and sizes. However, open questions still remain especially regarding the sediments that later fill up these basins. We aim to stimulate future research and promote exchange between researchers working around the Alps and the northern central European lowlands.

Previous glaciations eroded below the ice deep valleys in the Alpine foreland, which, with their sedimentary fillings, witness the timing and extent of these glacial advance–retreat cycles. Drilling such sedimentary sequences will thus provide well-needed evidence in order to reconstruct the (a)synchronicity of past ice advances in a trans-Alpine perspective. Eventually these data will document how the Alpine foreland was shaped and how the paleoclimate patterns varied along and across the Alps.

We used a combination of remote sensing, field investigations, and laboratory analysis to map and characterize abandoned river channels within the French Upper Rhine alluvial plain. Our results show five major paleochannel groups with significant differences in their pattern, morphological characteristics, and sediment filling. The formation of these paleochannel groups is attributed to significant changes in environmental processes in the area during the last ~ 11 700 years.

Short summary
A loess sequence in SW Germany was investigated using a high-resolution multi-method approach. It dates to 34–27 ka and comprises layers of initial soil formation. Drier conditions and a different atmospheric circulation pattern during the time of deposition are expected as the soil layers are less strongly developed compared to similar horizons further north. Dust accumulation predates the last advance of Alpine glaciers, and no loess deposition is recorded for the time of maximum ice extent.

We used a two-step approach with limited sampling effort in existing storm water infrastructure to illustrate the risk of biocide emission in a 2 ha urban area 13 years after construction had ended. First samples at a swale confirmed the overall relevance of biocide pollution. Then we identified sources where biocides were used for film protection and pathways where transformation products were formed. Our results suggest that biocide pollution is a also continuous risk in aging urban areas.

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.

This study investigates the Khur Basin in central Iran, a crucial area for understanding landscape history, past environmental changes, and potential human migration. By analysing the sedimentary archives and mapping landforms, six stages of landscape development were identified, linked to the climate shifts over the late Quaternary period. The findings provide a detailed understanding of how a desert environment, including alluvial fans, dunes, and playas, developed in response to changing climates.

We tested the reliability of infrared radiofluorescence (IR-RF) dating of K-feldspar on samples of known age. We compare several measurement protocols and analysis variants and determine the most appropriate version. Additionally, we compare these results with those obtained using infrared photoluminescence (IRPL), an alternative dating method for K-feldspar, for the same samples. Our results confirm the dating potential of IR-RF and highlight similarities and differences to other methods.

Geological glacial features such as moraines can be used to construct the environment of former times. While sands may indicate colder phases, soils and peat preserved witness warm phases. Using various dating techniques, the ages of such features can be obtained. This is important in order to get an understanding of the climate of the past, in this study on the extent of the ice marginal position in Schleswig-Holstein.

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.

This paper aims to reconstruct Middle Bronze Age (MBA) land use practices in the northwestern Alpine foreland (SW Germany, Hegau). We used a multi-proxy approach including biogeochemical proxies from colluvial deposits in the surroundings of a MBA settlement, on-site archaeobotanical and zooarchaeological data and off-site pollen data. From our data we infer land use practices such as plowing, cereal growth, forest farming and use of fire that marked the beginning of major colluvial deposition.
