VEGETATIONAL DEVELOPMENT DURING THE LATE-WURM AT LOBSIGENSEE (SWISS PLATEAU). STUDIES IN THE LATE QUATERNARY OF LOBSIGENSEE 1.
Lobsigensee is a small lake situated northwest of Bern at 514 m asl and was covered by Rhone ice during the Wurm glaciation. Palynological and plant macrofossil studies of a Late-Wurm deposit in the littoral are presented. The stratigra-phy of the sediments is from bottom to top: sand, sandy clay, c...
