Glacial erosion and deposition (8:30 am – 12:30 am, Audimax)
Leaders: Lukas Gegg, Jörg Lang
This workshop will focus on aspects of erosion and deposition by (paleo)glaciers, their interactions with the landscape, and their traces in the geological record. The workshop starts with a brief introduction by Gaudenz Deplazes & Jan Piotrowski. It will be divided into 3 thematic blocks, each comprising 5 short presentations of 3 minutes each (max. 2 slides) and around 90 minutes discussion time at the posters in front of the lecture hall. The workshop ends with a final discussion in the plenum (~60 min).
