| contents | Pollen analytical investigations of glacier ice from the Kesselwandferner in the Ötztal Alps, Tyrol, generally confirmed the palynologycal findings of Vareschi (1942) and brought new results. Annual layers were found which distinguish themselves by an increased content of Pl:cea pollen according to extreme Picea-blooming years. These can be used as "guiding horizons" in the firn-area of the glaciers. Long distance transport of African pollen (Ephedra) was proved. The absolute average pollen rain in 3300 m was determined by 28.000 pollen grains per year and dm**2. The investigation of fens near glaciers made it possible to determine the oscillations of the tree-line and the forest-linc and to date them by 0-14. These oscillations could be connected with moraines also dated by 0-14. Oscillations of the forest-line and thus probably glacier oscillations, too, could be determined for the period from 6700 to 6000 B.C. and the periods about 4500, 2600 and 1600 B.C. |
