   Dec 1, 2021 · Our results suggest that the trough morphology is considerably controlled by the underlying bedrock geology. Due to relatively high erosional resistance, resulting high relief and constrained ice flow conditions, the overdeepening is inner-Alpine-like and narrow across the Folded Jura.

   Oct 1, 2018 · Bedrock mega-grooves are assemblages of straight and parallel troughs eroded in bedrock, typically over 1000 m in length; most sites occur within the limits of the Last Glacial Maximum, both on- and off-shore.

   Oct 15, 2017 · Our results reveal an unexpectedly complex trough morphology that appears to be closely related to the bedrock geology. Two sub-basins are incised into calcareous marls and Molasse deposits, and are separated by a distinct ridge of Jurassic limestones, indicating strong lithological control on erosional efficiency.

   Is trough morphology related to bedrock geology?

   • Our results reveal an unexpectedly complex trough morphology that appears to be closely related to the bedrock geology. Two sub-basins are incised into calcareous marls and Molasse deposits, and are separated by a distinct ridge of Jurassic limestones, indicating strong lithological control on erosional efficiency.

   Is trough morphology inertia?

   • This suggests that there is a certain inertia in trough morphology, which can adjust only gradually to bedrock changes. This hypothesis is supported by the slow and gentle widening of the GST after the transition from the FJ into the northward adjacent Molasse.

   Does rock mass strength affect glacial trough cross section?

   • Several authors (e.g. Augustinus, 1992; Brook et al., 2004) have reported a correlation of rock mass strength and glacial trough cross section, with steep and narrow troughs developing in resistant bedrock, and wide and shallow troughs in weak lithologies. However, effects of more complex patterns of bedrock lithology have hardly been studied.

   What morphology supports the overdeepening of the Mesozoic bedrock?

   • The straight and/or kinked morphology of those GST sections incised into Mesozoic bedrock support the idea that the overdeepening, and the likely preceding fluvial valley system ( Ziegler and Fraefel, 2009 ), could follow discrete fault zones in the bedrock (similar to e.g. the inner-Alpine valleys of the rivers Rhone and Adda).

   Is a gravel layer at 245 m asl a coarse-grained sediment?

   • With regard to our seismic measurements (which are in good accordance with Pietsch and Jordan, 2014 ), we interpret a singular gravel layer at 245 m a.s.l. as coarse-grained sediment at the base of the Gebenstorf-Stilli Trough, but a significantly deeper trough base is possible at this position.

   How does a trough erode?

   • The trough shallowing culminates in a bedrock ridge whose top lies close to the lowest known Pleistocene base level (i.e. in non-overdeepened position). Further north, erosion depth increased again resulting in a second sub-basin.
