Short summary
Electron spin resonance (ESR) thermochronometry can be used to determine rock temperature changes, which occur as rocks move towards Earth's surface in response to uplift and surface erosion. We use samples from a known-temperature borehole to validate the method, by constraining the thermal sensitivity of quartz ESR signals in the laboratory. Whilst we are able to recover temperature successfully with the Al-centre signals, the Ti-centre signals overestimate the borehole temperature.

The OSLThermo and ESRThermo MATLAB libraries simulate how luminescence signals in feldspar and electron spin resonance signals in quartz minerals accumulate and fade over time, enabling reconstruction of recent rock cooling and surface temperature changes. By sharing these tools openly, we hope to promote collaboration, reproducibility, and broader use and development of these ultra-low-temperature thermochronology methods.

We apply quartz 3He paleothermometry along two deglaciation profiles in the European Alps to reconstruct temperature evolution since the Last Glacial Maximum. We observe a 3He thermal signal clearly colder than today in all bedrock surface samples exposed prior the Holocene. Current uncertainties in 3He diffusion kinetics do not permit distinguishing if this signal results from Late Pleistocene ambient temperature changes or from recent ground temperature variation due to permafrost degradation.

Pecube, a 3D thermal-kinematic software that predicts thermochronometer data, has been widely used to constrain the past evolution of mountain belts, but its accessibility and application is still limited. This work overcomes this limitation by offering a graphical user interface to Pecube, PecubeGUI, and by broadening its application to a wider range of tectonic settings through the implementation thermochronometer prediction models in line with the most recent research developments.

Short summary
Thermochronometry data inversions using the Pecube software are useful to constrain the past evolution of mountain belts. However, configuring the neighbourhood algorithm for Pecube inversions remains challenging for new Pecube users. This contribution aims to provide intuition and guidelines for setting up NA-Pecube inversions to support informed decision-making. It forms part of a broader effort to improve the accessibility of Pecube to new users.

By combining innovative dating techniques and glacier modelling, we studied how sediment is produced, transported, and stored within the Mer de Glace catchment in the French Alps. We show that whilst sediment is transported through the glacier in less than a millennium, some sediment can be stored for many thousands of years before being re-entrained into glacial transport. This long-term storage affects how landscapes evolve and how climate signals are preserved during deglaciation.

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.

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
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.

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.
