Accurate dating of Quaternary fluvial archives is critical: spatio-temporal patterns of river incision unfold uplift history of the Variscan Rhenish/Ardenne Massif (N. Europe)

Résumé: The Rhenish/Ardenne Massif experienced significant intraplate uplift during the Plio-Quaternary, but its timing, rates, and driving mechanisms have long remained debated due to limited chronological control. Recent dating of fluvial terraces and cave levels using cosmogenic nuclides, ESR, and luminescence methods now provides more robust age constraints. Compiled data, along with new age results, reveal a massif-wide peak in river incision during the Early to Middle Pleistocene, with a notable time lag between the southeastern and northwestern margins. Earlier incision along the Rhine–Moselle system compared to the Meuse supports the idea of a northward-migrating uplift wave driven by regional tectonic stresses linked to the Alps.
