Mid-Pleistocene uplift-induced acceleration of incision in the lower Meuse valley constrained by cosmogenic burial ages

Ewerton da Silva Guimarães, Freek S. Busschers, Duna Roda-Boluda, Naki Akçar et autres

The succession of fluvial terraces situated in the lower Meuse River (Netherlands–Belgium border, NW Europe) provides a morpho-sedimentary record of regional Quaternary landscape evolution. Although these terraces have been extensively studied in the past, the mechanisms and especially the timing related to …

Human occupation of the Afroalpine Bale Mountains at the onset of the African Humid Period

Götz Ossendorf, Minassie Girma Tekelemariam, Noora Taipale, Alexander Raphael Groos et autres

Context: The reasons for the intermittent human use of harsh Afroalpine environments in prehistory remain unclear. High-resolution glacial and archaeological chronologies from Ethiopia's Bale Mountains now offer insights into landscape change and human adaptations at high altitudes. Objectives: This study investigates the …

An extensive MIS 12 Alpine glaciation in the Jura Mountains: insights from cave sediments and burial dating

Neal A. Mathes, Marc Luetscher, Susan Ivy-Ochs, Catharina Dieleman et autres

The Middle Pleistocene glaciations of the Alps and the Jura Mountains are poorly understood relative to the Last Glacial Maximum (LGM). However, they played a critical role in shaping the landscape of the Northern Alpine Foreland. In the Jura Mountains, karstic features …

Quantifying erosion in a pre-Alpine catchment at high resolution with concentrations of cosmogenic 10 Be, 26 Al, and 14 C

Chantal Schmidt, David M. Mair, Naki Akçar, Marcus Christl et autres

Quantifying erosion across spatial and temporal scales is essential for assessing different controlling mechanisms and their contribution to long-term sediment production. However, the episodic supply of material through landsliding complicates quantifying the impact of the individual erosional mechanisms at the catchment scale. …

Unravelling the evolution of the Frébouge polygenetic cone in Val Ferret (Mont Blanc Massif)

Catharina Dieleman, Philip Deline, Susan Ivy Ochs, P. Hug et autres

Proglacial settings in the Alps are typically polygenetic, often characterized by a complex and discontinuous interplay between glacial, fluvial and gravitational processes. These processes yield high volumes of sediments, which usually exceed their transportation capacity. The excessive proglacial sediment load leads to …

Lateglacial to Early Holocene glacier fluctuations in the northern Valaisian Alps

Mattia Binaghi, Naki Akçar, Susan D. Ivy-Ochs, Serdar Yeșilyurt et autres

Abstract The northern Valaisian Alps represents a glacially overprinted landscape, characterized by abundant glacial deposits and landforms. Well-preserved moraine systems, commonly found in the region, were deposited by glacier fluctuations after the Last Glacial Maximum (LGM). In this study, we focus on …

Strong Variation of Detrital 10 Be Denudation Rates with Topographic Heterogeneity and Catchment Size - A Tale of Two Contrasting Swiss Catchments

David M. Mair, Jana von Allmen, Patrizia Ruffiner, Mattia Binaghi et autres

Quantifying erosion relative to topography is essential for understanding landscape evolution. Cosmogenic ¹⁰Be in river sediment is widely used to estimate catchment-wide denudation over millennial timescales. These rates help identify drivers such as tectonic uplift, periglacial processes, precipitation gradients, bedrock erodibility, landslides, …

Luminescence Surface Exposure Dating and Paleoseismic Insights from the Kuşadası Fault Zone, Western Türkiye

Mustafa Softa, Eren Şahi̇ner, Joel Q.G. Spencer, Hasan Sözbilir et autres

Exposure dating has become a critical tool in addressing specific geoscientific challenges, including glaciology, active fault studies, and environmental reconstructions. Cosmogenic exposure dating (e.g., 36Cl) and luminescence surface exposure dating are widely used techniques, often complementing each other. In active tectonic studies …

Linking highly variable Detrital 10Be Erosion Rates to heterogeneous Topography in Small and Alpine Catchments

David M. Mair, Jana von Allmen, Patrizia Ruffiner, Mattia Binaghi et autres

Quantifying erosion and linking its topographic imprint to underlying controls is critical for understanding landscape evolution and sediment dynamics across time and space. Over the past decades, catchment-wide denudation rates from cosmogenic 10Be concentrations in river sediment emerged as a standard method …
