p.286: The middle gravel unit (‘Iberig-Schotter’) reveals no petrographic relation to the glacigenic deposits, but the two upper units are again genetically related (‘Bärengraben-Schotter’, ‘Bärengraben-Till’). Interestingly, the uppermost part of ‘Iberig-Schotter’ includes overbank deposits and palaeosols. This indicates, firstly, that glacial deposition was separated by sedimentation during warmer periods, and, secondly, that the fluvial drainage level remained similar during the glacial and non-glacial times of this period.
