Abstract
This paper is a discussion and interpretation of the stratigraphical and pollenanalytical material presented by the author in Vol. II of this paper: "Description of sections and pollen-analyses - A presentation of the bog-geololical material".Eight pollen diagrams from the bog Aamosen are presented, covering Preboreal, Boreal, and early Atlantic periods.On the basis of the curves of the diagrams an attempt is made to elucidate the development of the vegetation in the area. The water-level in the basin is determined from the succession of sediments and from the pollen diagrams, and a possible alternation with the oscillations of the Littorina sea is pointed out.The climate development is discussed, and a climatic oscillation in the early Atlantic period is deduced from the courses of the curves for Hedera and Viscum.Finally the habitation at the Maglemose settlement Verup 5 in Aamosen is interpreted, and individual phases of it are pollen-analytically dated.
Highlights
JAPETUS STEENSTRUP laid the foundations of bog geology proper in this country with his investigations of forest bogs in northern Zealand (JAPETUS STEENSTRUP, 1842)
If the values in the table above are compared with diagram P.33, it appears from analyses 1- 2 from Hesselbjerggaard, which represent layer 2, that this layer was formed at the same time as, or immediately after, the raising of the "floating island" at Verup, while analysis 3, from immediately above the thin layer of sand, shows that this layer was formed during the maximum rise in the water-level
In the Nil0se Diagram (Baad I) its rational limit is at the zone border IV-V, but in one of the Verup diagrams (P.28,30) we find individual occurrences of Cladium even in zone IV
Summary
JAPETUS STEENSTRUP laid the foundations of bog geology proper in this country with his investigations of forest bogs in northern Zealand (JAPETUS STEENSTRUP, 1842). As for the topography and history of the area, a full account is given in THERKEL MATHIASSEN's large publications "STENALDERBOPLADSER I AAMOSEN" (1943) and "NORDVESTSJJELLANDS OLDTIDSBEBYGGELSE" (I 959) In the former , which deals with the archaeological material from the Aamose area obtained up to 1942, there are contributions from natural scientists: D EGERB0L gives an accounc of the zoological material found , and TROELS-SMITH presents the results of the geological investigations and preliminary datings. As it was quite clear that the Verup diagrams originated in the shore zone, where local conditions influenced both the sediments and the presence of pollen, the diagrams from Nil0se; Baad I (Fig. 1, No 2) and Aamosen; N.1.000; 0.2.840 (Fig. I, No 11) were analyzed to elucidate contemporary conditions in the open lake Later still another diagram from an area close to the shore was analyzed (the settlement Ulkestrup Lyng, 0st - named Ul.0., see Fig. 1, No 6), and, the diagram connected with the large flint pick (Fig. 1, No 3) was revised, and re-calculated according to the principles used for the rest of the material. A report by ULRIK M0HL on the bones found at the settlement is included in this paper
