New data on the distribution and age of glaciolacustrine deposits on the Zimny, Abramovsky, Lyamitsky and Tersky shores of the White Sea are presented. It was possible to trace the dynamics of the glaciation development in the studied area during the LGM, as well as to reconstruct the stages of transition of the White Sea basin from the glacier to the sea basin. The glaciolacustrine sediments of the Abramovsky shore characterise the stage of glaciation onset, while those of the Zimny shore - the initial stage of glacier degradation, when a series of small proglacial water bodies adjoined its marginal zone. The glaciolacustrine sediments studied on the Lyamitsky and Tersky shores were formed in large proglacial lakes that immediately preceded the penetration of the Barents Sea waters into the White Sea basin, as a result of which its gradual salinisation occurred and marine sedimentation began.
