A first chronological framework for fluvial terrace deposits of the Kampar Kanan River, Indonesia Open
Late Quaternary landscape evolution in tropical environments, such as Indonesia, remains poorly constrained due to limited prior studies and mineral properties that are challenging for luminescence dating. In this study, single- and multi-…

ESR-thermochronometry of the MIZ1 borehole, Tono, Japan Open
Electron spin resonance (ESR) dating of quartz minerals offers a significant advantage over luminescence dating because of its later signal saturation. We seek to exploit this to develop a thermochronometry system capable of resolving rock…
Electron spin resonance (ESR) signals in calcite: a novel thermochronometer to constrain carbonate mountain erosion? Open
The interaction between surface processes, climate and tectonics determines the landscape in alpine regions, with lithology playing a key role. Carbonate rocks, which cover a significant portion of Earth’s terrestrial surface, are mo…
­­­­­Exhumation of the western European Alps (Switzerland) using ultra-low temperature and classical thermochronometry and numerical modeling (Pecube)  Open
The impact of Quaternary glaciation on the exhumation of the western European Alps remains unclear due to a lack of geochronological methods that cover the timespan of 103-106 years. In this study, we combine new ultra-low temperature (

Unveiling the impact of Quaternary climate on mountain erosion: new insights from the Japanese Alps using novel trapped charge thermochronometry Open
The influence of Quaternary climate (i.e., glacial-interglacial cycles) on mountain topography remains a topic of debate, largely due to the challenges associated with measuring surface processes over the recent geological past. A compelli…

Investigating temperature sensitivity of quartz Electron Spin Resonance (ESR) thermochronometry: Insights from the Anadarko Basin (Oklahoma, USA) Open
Low-temperature thermochronology dates mineral cooling through the upper crust, enabling us to constrain the rate and timing of landscape evolution over a range of spatial-temporal scales (Reiners et al. 2005). However, constraining recent…
Older than expected: fluvial aggradation of the Rhine's main terrace at Kärlich dated around 1.5 Ma by electron spin resonance Open
The Mülheim–Kärlich clay pit (Kärlich hereinafter) is located along the Middle Rhine Valley (MRV), about 10 km north-westward of the city of Koblenz (Fig. 1a). Owing to its > 30 m thick Quaternary sequence (Fig. 1b), it perhaps represents …

Miocene to recent precipitation history of the central Atacama Desert as reconstructed from a clay pan record in the Coastal Cordillera, northern Chile.  Open
Hyperaridity is the major limiting factor of Earth-surface processes and biological activity in the Atacama Desert of northern Chile, one of the oldest and driest deserts on Earth. On geological timescales, however, the general aridity, wh…
­­­­­ESR-thermochronometry in the western European Alps (Switzerland)  Open
The western European Alps are characterised by deeply incised valleys, however the timing of their formation and the impact of Quaternary glaciation on rates of erosion remains disputed. This is mainly due to a lack of geochronological met…

Will ESR thermochronometry reveal the timing of Rhône valley incision? Open
The impact of Quaternary climate change on landscape evolution, and more specifically the timing of incision of the overdeepened Alpine valleys, remains difficult to quantify with existing thermochronometric methods. Thermochronometers are…

High-relief exhumation history in the Japanese Alps within the past 1 Ma inferred from trapped charge thermochronometry Open
The interactions between Earth surface processes, climate and tectonics determine the landscape in mountain regions. The Japanese Alps uplifted throughout the Quaternary and now reach elevations of up to 3,000 m. However, quantifying relie…
Potential impacts of chemical weathering on feldspar luminescence dating properties Open
Chemical weathering alters the chemical composition of mineral grains. As a result, trapped-charge dating signals of primary silicates may be progressively modified. In this study, we treated three feldspar specimens to understand the effe…
