Litorina Sea sediments of ancient Vääna Lagoon, northwestern Estonia

Abstract

Vääna Lagoon (59°22'30''N, 24°25'00''E) is located 25 km west of Tallinn in ancient Vääna Klint Bay at a 22 m Litorina Sea isobase. Lagoonal deposits were reinvestigated and new results of pollen, diatom, loss-on-ignition, magnetic susceptibility analyses, and radiocarbon datings were used for the reinterpretation of previous studies. The onset of the Litorina Sea transgression in the region is dated to 8300 cal yr BP and culmination to about 7000 cal yr BP. New material shows a single Litorina Sea transgression and denies the twofold transgression suggested earlier.
