MIDDLE WEICHSELIAN MARINE-SEDIMENTS FROM EASTERN KATTEGAT, SCANDINAVIA

Foraminifera, pollen, lithology and radiocarbon dates from a core in t he southern Kattegat provide a rare opportunity to obtain data relatin g to environmental conditions during the Middle Weichselian in the off shore Kattegat. This core is also correlated with an adjacent second c ore. Redeposited Eemian foraminifera and pollen occur in the Middle We ichselian sediments. This is interpreted as a result of reworking by a n active Middle Weichselian ice present in, or advancing from, a north easterly to easterly direction. During a second phase the Middle Weich selian sediments were compacted, probably a result of overriding by an ice from the northeast during the Middle Weichselian and/or the Late Weichselian Maximum. The Middle Weichselian sequence is overlain by a Holocene sequence which, in turn, is overlain by an admixture of Middl e Weichselian and Holocene sediments. This mixing may be a result of t ectonic activity some time between 7300 and 1000 BP. The core ends in Holocene fine sediments representing the last c. 1000 years.
