摘要：
We studied the grain-size, mineralogical and chemical composition, physical properties, radiocarbon age, spore-pollen spectra, and diatom composition in the sediments from core PSh-2537 sampled in the West Gotland Basin. Four lithological-stratigraphic units were distinguished: varved clays of the Baltic Ice Lake, black and black-gray (sulfide) clays of the Yoldian Sea, gray clays of Ancylus Lake, and greenish-gray sapropel-like littorine and post-littorine silts of the marine stage of the Holocene, These units differ from each other both in their matter composition and in plant remains. In the littorine silts, the determined C-org concentration reached from 1.5 to 10.35%. The conditions of the sediment accumulation and the stages of evolution of the West Gotland Basin over the post-glacial time are characterized.
