| Summary: | Marine Quaternary sediments at Skaershoj in the western Limfjord area have been investigated. They seem to represent a transgression of Late Elsterian age followed by a drop in water level also within the Late Elsterian. The lowermost part of the Skaershoj deposit shows that the sea may have transgressed into an area with glacial lakes. Poor foraminiferal assemblages in the lower part are succeeded by rich arctic faunas, which indicate an environment with normal marine salinity and a water depth of more than about 15 m. Drifting ice in the area is indicated by the content of ice rafted stones in the sediments. An extremely low number of both foraminiferal and ostracod species also suggests a glaciomarine environment. The water seems to have been shallower and the accumulation rate higher during the deposition of the upper part of the sequence. A rhythmic change in grain size through these shallow marine arctic deposits has been interpreted as annual variations caused by ice cover during the winter. -English summary |
