Short summary
The chronostratigraphy of the Rhine’s main terrace along the Middle Rhine Valley (MRV) is poorly constrained. This study fills this gap by using electron spin resonance (ESR) dating of quartz grains collected from the famous Kärlich site. Consistent ESR results date this terrace to ~1.5 Ma and have far-reaching implications as they numerically constrain, for the first time, the aggradation time of key terrace deposits along the MRV, providing new insights into the Rhine’s Quaternary evolution.

Short summary
Luminescence dating of feldspar minerals is widely applied in geology and archaeology. However, the luminescence of feldspar is prone to signal loss termed anomalous fading, which must be accounted for to avoid age underestimation. Here, we critically review the different mathematical approaches for anomalous fading correction, and present new, computationally efficient, analytical expressions for the two most ubiquitous fading correction schemes.

Short summary
This study shows that calcium (Ca) preserves soil organic carbon (SOC) in acidic soils, challenging beliefs that their interactions were limited to near-neutral or alkaline soils. Using spectromicroscopy, we found that Ca was co-located with a specific fraction of carbon, rich in aromatic and phenolic groups. This association was disrupted when Ca was removed but was reformed during decomposition with added Ca. Overall, this suggests that Ca amendments could enhance SOC stability.

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.

Short summary
We found that novel ecosystems created by glacier retreat are first characterized by an increase in plant diversity that is driven by a shift in soil texture. Plant diversity in turn increases soil organic matter and nutrient. Soils gradually acidifies and leads to a final stage where a dominance of few plant species reduces plant diversity. Understanding plant–soil interactions is crucial to anticipate how glacier retreat shapes biodiversity and landscapes.

Short summary
Glacial and non-glacial processes have left a strong imprint on the landscape of the European Alps, but further research is needed to better understand their long-term effects. We apply a new technique combining two methods for bedrock surface dating to calculate post-glacier erosion rates next to a Swiss glacier. Interestingly, the results suggest non-glacial erosion rates are higher than previously thought, but glacial erosion remains the most influential on landscape evolution.

Wave-transported boulders are important records for storm and tsunami impact over geological timescales. Their use for hazard assessment requires chronological information. We investigated the potential of a new dating technique, luminescence rock surface exposure dating, for estimating transport ages of wave-emplaced boulders. Our results indicate that the new approach may provide chronological information on decadal to millennial timescales for boulders not datable by any other method so far.

Short summary
A new approach to reconstruct the temporal variation of rock surface temperature using the thermoluminescence (TL) of feldspar is introduced. Multiple TL signals or thermometers in the range of 210 to 250 °C are sensitive to typical surface temperature fluctuations and can be used to constrain thermal histories of rocks over ~50 kyr. We show that it is possible to recover thermal histories of rocks using inverse modeling and with δ18O anomalies as a priori information.

Short summary
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.
