Аннотация: Based on field lithostratigraphic studies, microfaunistic and palynological analyses, and optically stimulated luminescence (OSL) dating of sediments exposed in the lower part of Quaternary sections along the Zimnii coast of the White Sea, it is established for the first time that they accumulated during the Boreal transgression in the beginning of the Last Interglacial under marine and coastal marine conditions and form the Upper Pleistocene Mikulinian Horizon. This is supported by the lithology; the species composition of foraminifers, ostracods, and aquatic palynomorphs; and the OSL ages in the range of 118–104 ka. The composition of benthic microfossils indicates that the beginning of the Boreal transgression along the entire Zimniicoast was characterized by a coastal marine basin with sea-ice cover and water depths of >50 m, as well as by high sedimentation rates and stratification due to inflow of melt/river waters. The coastal marine sedimentation conditions were dominant during the regression stage along the Zimnii coast.
