Laser Ablation (<span>U‐Th‐Sm</span>)/He Dating of Zircons: Analytical Age Bias and its Consequence for Studying Detrital Zircon Populations Open
The in situ (U‐Th‐Sm)/He and U/Pb laser‐ablation double‐dating procedure is a valuable method that can provide a large dataset relatively efficiently in contrast with conventional bulk helium thermochronometry. In this study, we evaluate t…

Investigating the Shallow to Mid-Depth (>100–300 °C) Continental Crust Evolution with (U-Th)/He Thermochronology: A Review Open
Quantifying geological processes has greatly benefited from the development and use of thermochronometric methods over the last fifty years. Among them is the (U-Th)/He dating method, which is based on the production and retention, within …

Orogenic evolution of Western Europe controlled by lithosphere evolution Open
<p>Processes driving orogenic styles and long-term isostatic versus dynamic support of the topography have been largely debated in domains of plate convergence. Tectonics of orogens reflect the interactions between mantle flow drivin…

Evolution of a low convergence collisional orogen: a review of Pyrenean orogenesis Open
The Pyrenees is a collisional orogen built by inversion of an immature rift system during convergence of the Iberian and European plates from Late Cretaceous to late Cenozoic. The full mountain belt consists of the pro-foreland southern Py…

Decoding low-temperature thermochronology signals in mountain belts: modelling the role of rift thermal imprint into continental collision Open
Resolving the timing of initiation and propagation of continental accretion associated with increasing topography and exhumation is a genuinely challenging task using low-temperature thermochronology. We present an integrated thermo-mechan…

Cenozoic mountain building and topographic evolution in Western Europe: impact of billions of years of lithosphere evolution and plate kinematics Open
The architecture and tectono-magmatic evolution of the lithosphere of Europe are the result of a succession of subduction, rifting and inputs from plumes that have modified the lithospheric mantle since the Neoproterozoic (750–500 Ma). The…

Reconstructing orogen dynamics from detrital geo-thermochronological signals in pro- and retro-foreland basins: A case sudy of the Pyrenees, France Open
<p>A bivergent orogenic belt and its foreland basins form an intimately coupled system for which cause-effect relationships have generated much debate. This is the case in the Pyrenees, where the contemporaneity of crustal thermal ev…

Reconstruction de la Dynamique Précoce d'un Orogène : Mise en évidence de la Transition Rifting-Collision dans le système est-pyrénéen (France) par la Géo-thermochronologie Open
Collisional orogens are classically described as the result of continental accretion of proximal margins. This accretion leads to the creation of relief and to the important export of erosion products in the directly adjacent foreland basi…

Thermochronological Evidence of Early Orogenesis, Eastern Pyrenees, France Open
In collisional orogens, distinguishing the thermal signature of early orogenesis from the preceding rift or from subsequent thermal events is a major challenge. We present an integrated geological and low‐temperature thermochronology study…
