Abstract

The Quaternary sequence of a boring from the island of Anholt, Denmark, comprises both marine and non‐marine sediments spanning a time interval from the Holocene to at least as far back as the Saalian. The oldest Quaternary sediments consist of a till and a glaciofluvial sand sequence. These are overlain by marine silty clays of Saalian to Eemian age. An interstadial (Flakket Interstadial) and a stadial (Kattegat Stadial) are identified in the late Saalian. This climatic fluctuation has been compared to the Allerød and Younger Dryas events at the Weichselian–Holocene transition. The Eemian sediments are followed by sand and non‐marine, varved clay overlain by 2 m of marine clay, which is correlated with the Middle Weichselian of the Skærumhede series. The marine clay is covered by silty clay and a thick sand sequence of non‐marine origin. The uppermost 2 m sediments may represent the Holocene coastal accretion on Anholt.
