Vegetational development during the Late-Würm at Lobsigensee (Swiss Plateau)
Lobsigensee is a small lake situated northwest of Bern at 514 m asl and was covered by Rhone ice during the Würm glaciation. Palynological and plant macrofossil studies of a Late-Wurm deposit in the littoral are presented. The stratigraphy of the sediments is from bottom to top : sand, sandy clay, c...
