Based on diatom analysis of lake bottom sediments, six diatom zones that correspond to paleoclimatic periods from the Bolling to Boreal time were recognized. Light was cast on the evolution pattern of diatom flora in Late Glacial and Holocene time. The time of the final melting of dead ice in the catchment basin was determined. Small quantities of diatoms in the sediments and large quantities of redeposited marine forms up to the end of the Late Dryas-early Preboreal period are reported. Diatoms began to evolve on a large scale in Lake Pertozero in Boreal time.
