Aeolian deposits cover 2.61% of the territory of Lithuania: the massifs of continental dunes prevail over the coastal ones. Forty datings from 7 boreholes of aeolian deposits have been carried out by the optically stimulated luminescence (OSL) method. The periods of aeolian activity were different for massifs of continental dunes and dunes of the Baltic Sea coast. In the massifs of continental dunes the aeolian processes started in the Late Glacial, after the melting of the Last Glaciation ice sheet, and finished at the climatic optimum of the Holocene,i. e. Atlantic period. Formation of coastal dunes is closely related with the different stages of development of the Baltic Sea, so the results of OSL dating of aeolian deposits are important for stratigraphic identification of marine terraces. The Medieval period of activation of aeolian processes caused by lumbering is reflected in aeolian deposits as well.
