Abstract

Succession of diatom phases in Late-Glacial lacustrine deposits at Niechorze, western Pomerania, Poland, permits recognition of two main stages in development of the basin. The early stage/Oldest Dryas, Bolling and the beginning of Older Dryas/is distinctive in discontinuities in diatom distribution resulting from sedimentary disturbances, and in poorly preserved and species-poor diatom assemblages dominated by Fragilaria pinnata. Diatoms were very aboundant at the late stage /the decline of Older Dryas, Allerod, and Younger Dryas/ and their ubiquity indicates and increased stability in the pattern of limnic sedimentation. At the late stage of basin development, the diatom assemblage was dominated by Fragilaria construens var. venter and F. brevistriata, but the contribution of Synedra spp. and Melosira italica was increasing towards the end of Younger Dryas.
