Boreas . Vol. 8, pp. 1–22. Oslo. ISSN 0300–9483. The West Bornholm basin is an approx. 1000 km 2 subbasin of the Bornholm basin just north of Bornholm. The basin has been mapped by acoustic profiling and sampling of the sea floor. The basin is eroded down into Mesozoic sediments which are downfaulted between basement horsts in the Fennoscandian Border Zone. The development of the Quaternary morphology is illustrated by maps of the surface of the bedrock, the glacial landscape beneath the varved clays, the recent topography combined with isopach maps of late Glacial and Holocene formations. Quaternary formations are defined and described. The brown, very fine grained varved clay is deposited as a conformable cover on the substratum. It is probably deposited from suspensions carried in the whole water body, while turbidity currents were of minor importance. The recent sedimentary environment is an example of a restricted, but not totally anoxic basin. The recent sediment is chiefly mud rich in organic matter (ca. 4% C org ). According to a rough estimate, the long‐term mean sedimentation rate of organic carbon is 6 g/m 2 /year. Article in Journal/Newspaper Fennoscandian Wiley Online Library Boreas 8 1 1 22 |
