The research focuses on overdeepenings in the former Rhine glacier domain north from Lake Constance in southwestern Germany. We expand the current knowledge of the Quaternary stratigraphy of the Lake Constance Amphitheatre by revealing two new drill cores, both reaching the quaternary base of two different overdeepened basins. As a result, we show that our investigated sediment successions are quite atypical for alpine foreland overdeepenings.

Drillings, outcrops, and seismic data provide insights into a glacial basin and a former river channel in northern Switzerland. Both are infilled with diverse (glacial, lacustrine, fluvial, colluvial) sediments attributed to three separate glaciations. The depth of the glacial basin depends strongly on the underlying rock type, which together with (hydro)fractures provides evidence on the conditions and erosion processes at the ice–rock interface.

The subdivision and distinction of gravel units is an important tool in terrestrial Quaternary stratigraphy but can be challenging. Here, we investigate the glaciofluvial infill of the Upper Rhine Graben as an archive of recurring Alpine glaciations. With the help of statistical approaches, we identify differences in petrographic compositions, thereby differentiating two units that are likely representative of the last and penultimate glaciation, which have previously been difficult to pinpoint.

The Tannwald Basin, explored by drilling and formed by repeated advances of the Rhine Glacier, reveals key geological insights. Ice-contact sediments and evidence of deformation highlight gravitational and glaciotectonic processes. ICDP DOVE 5068_1_C core data define lithofacies associations, reflecting basin infill cycles, marking at least three distinct glacial advances. Integrating these findings aids understanding the broader glacial evolution of the Lake Constance amphitheater.

We determined ¹⁰Be concentrations in moraine boulder surfaces in the southern Black Forest, SW Germany. We applied three independent dating methods to younger lake sediments. With the aid of independent age datasets, we calculated the growth of ¹⁰Be concentrations in moraine boulder surfaces.
