The Late Weichselian freshwater beds at Nørre Lyngby. C-14 dates and pollen diagram

An additional layer sequence below the well known stratigraphical succession in the central part of the Late Weichselian freshwater basin at Nørre Lyngby, Jylland, has given rise to a new pollen diagram and a series of C-14 datings from the pollen profile and from the allochthonous peat layer in the southern part of the section. The stratigraphical position of the peat layer should be below the layers of the pollen profile. The C-14 dates from the peat layer span from late Bølling into early Allerød , and accordingly the layers in the pollen profile are younger than early Allerød. The C-14 dates from the pollen profile indicate that most of the dated material has been redeposited from the peat. The pollen diagram is divided in stages A, B and C. A and B are referred to the Allerød, C possibly to Younger Dryas. In lversen's 1942 pollen diagram his zones lc and II a re correlated with B, and III with C in the present diagram.
