Varve chronology of the glacial sediments in Blekinge and northeastern Skåne, southeastern Sweden

Abstract

In sections and cores from an area of the Baltic Ice Lake in Blekinge complete varve series of fine‐grained glacial sediments have been found. It is possible to divide the series, from bottom to top, into four varve types. A core from Karlshamn in Blekinge shows most varves of the investigated localities, in all 355 varves. Antevs' (1915) local chronology has been used, as the most recent revision of the Swedish time scale has not yet been completed. The chronology in this investigation ranges from ‐ 325 to + 315, or 640 years. The varve chronology and the velocity of the ice recession, c. 90 m/year in northeastern Skåne, shows good agreement with the work of Antevs, whose unpublished diagrams have been re‐worked and used in this investigation.
