Abstract

The Kola Peninsula is one of the key areas for the study of postglacial development of northern Europe. The repeated formation of ice shields during the Pleistocene determined the peculiar features of the relief, structure of Quaternary sediments, and recent landscapes of the peninsula. The paleogeographic reconstructions available for the last 10–11 ka are based on results of the palynological analysis of lacustrine and boggy sediments [3–5, 9–11] and, to a lesser extent, on diatoms from the lacustrine sediments [7, 8]. In this communication, we present the first data on diatom assemblages from peat sections of the central Kola Peninsula and their detailed radiocarbon ages. The high sensitivity of lacustrine–boggy ecosystems to environmental changes made it possible to define several Holocene diatom assemblages and to correlate their succession with regional climatic events and variations in the local base level.
