Timing of European fluvial terrace formation and incision rates constrained by cosmogenic nuclide dating

Original language description

Age constraints of late Cenozoic fluvial deposits are important for addressing surface processes questions such as the incision rates of rivers, and tectonic vs. climate controls on sedimentation and denudation. Fluvial sequences are often dated with relative age constraints such as magneto- or biostratigraphy. Absolute age constraints of fluvial deposits are not always possible as datable material is missing (e.g., no organic matter for carbon dating) or techniques do not cover the age ranges of the fluvial deposits (e.g., carbon dating in early Pleistocene terraces). Different dating techniques based on in situ- produced cosmogenic nuclides allow the age determination of fluvial deposits back to 5 Ma. In this study, cosmogenic depth profile dating and isochron burial dating were applied to four different river systems in Europe spanning 12o of latitude. Isochron burial age constraints of four selected terraces from the Vltava river (Czech Republic) range between 0.96±0.23 to 2.09±0.51 Ma. An isochron burial age derived for the Allier river (Central France) is 2.00±0.22 Ma. Five terrace levels from the Esla river (NW Spain) were dated between 0.08 +0.04/-0.01 Ma and 0.59 +0.13/-0.20 Ma with depth profile dating. The latter age agrees with an isochron burial age of 0.52±0.20 Ma. The successfully dated terrace level from the Guadalquivir river (SW Spain) resulted in an isochron burial age of 1.79±0.19 Ma. Results indicate that the cosmogenic nuclide-based ages are generally older than ages derived from previous relative age constraints. These results highlight a potential uncertainty in relative age constraints used to understand climate drivers for terrace formation within Europe and elsewhere.
