Foraminifera, pollen, and molluscs have been investigated in marine Late Weichselian and Holocene deposits from borings southeast of Frederikshavn. The results from the different biostratigraphical methods are co-ordinated. At least 14 m of sediments seem to be represented from the Younger Dryas Chronozone, and the thickness of the Holocene varies from 9 to 14 m in the three borings. The base of the Holocene occurs between 23.5 and 28.5 m below present day sea-level. A thin unit from the Boreal or possibly the Preboreal Chronozone seems to exist in two of the borings, but a considerable hiatus occurs between this and marine Subboreal and Subatlantic deposits in the study area.
