Late Cenozoic evolution of the Ariege River valley (Pyrenees) constrained by cosmogenic Al-26/Be-10 and Be-10/Ne-21 dating of cave sediments

Autor: Sartegou, A., Blard, P. H., Braucher, R., Bourles, D. L., Sorriaux, P., Zimmermann, L., Laffitte, A., Tibari, B., Leanni, Laetitia, Guillou, V., Bourdet, A., ASTER Team

Despite increasing knowledge on the orogenic phases of the Pyrenees, the Neogene evolution of the range re-mains poorly constrained. The central Pyrenees, particularly the Ariege River valley and its terrace systems and glacial extensions, are key to

Plio-Quaternary landscape evolution in the uplifted Ardennes : new insights from Al-26/Be-10 data from cave-deposited alluvium (Meuse catchment, E. Belgium)

Autor: Rixhon, G., Braucher, R., Bourles, D. L., Peeters, A., Demoulin, A., Leanni, Laetitia, Aster Team

Despite a wealth of recent studies dealing with the evolution of the drainage network in the uplifted Ardennes massif (E. Belgium), especially from the Middle Pleistocene onwards, the Ardennian landscape evolution and long-term incision rates in the

Retention of Be-10, Cs-137 and Pb-210(xs) in soils : impact of physico-chemical characteristics

Autor: de Tombeur, F., Cornu, S., Bourles, D. L., Duvivier, A., Pupier, J., Brossard, Michel, Evrard, O., Equipe Aster

The Be-10, Cs-137 and Pb-210(xs) radionuclide fallout has been used for the last several decades to quantify various soil and geomorphological processes on different time scales. However, a basic assumption of the studies relying on these radionuclid

Post-Last Glacial Maximum glacier fluctuations in the southern Ecrins massif (westernmost Alps) : insights from Be-10 cosmic ray exposure dating

Autor: Hofmann, F. M., Alexanderson, H., Schoeneich, P., Mertes, J. R., Leanni, Laetitia, Aumatire, G., Bourles, D. L., Keddadouche, K., ASTER Team

Only a few chronological constraints on Lateglacial and Early Holocene glacier variability in the westernmost Alps have hitherto been obtained. In this paper, moraines of two palaeoglaciers in the southern ecrins massif were mapped. The chronology of

Design and performance of an automated chemical extraction bench for the preparation of Be-10 and Al-26 targets to be analyzed by accelerator mass spectrometry

Autor: Keddadouche, K., Braucher, R., Bourles, D. L., Baroni, M., Guillou, V., Leanni, Laetitia, Aumaitre, G.

The growing number of studies based on data provided by the accelerator mass spectrometry (AMS) technique from increasingly diverse matrices implies that developing very effective and reproducible sample processing techniques is crucial to meet the d

Deciphering landscape evolution with karstic networks : a Pyrenean case study [+ Corrigendum in Quater. Geochronol. 2020, vol. 57, art. 101050, 2 p.]

Autor: Sartegou, A., Bourles, D. L., Blard, P. H., Braucher, R., Tibari, B., Zimmermann, L., Leanni, Laetitia, Aumaitre, G., Keddadouche, K., ASTER Team

The rates and chronologies of valley incision are closely modulated by the tectonic uplift of active mountain ranges and were controlled by repeated climate changes during the Quaternary. The continental collision between the Iberian and Eurasian pla
