The main lithological characteristics of the alluvial sands, gravels and pebbly deposits in the particular layers of the six terrace of the Dnister River (the Loyeva level) near Sambir, Lviv oblast, west Ukraine, are given. The textural features of these beds, the granulometrical and petrographical composition of the alluvium, roundness of the gravelly and pebbly material, the orientation of pebbles (imbrication), and the other features are characterized. On the base of the obtained results of the lithological investigation the conditions of sedimentation of the alluvial sands, gravels and pebbly deposits of the six terrace of the Dnister River (the Loyeva layer) at the environs of Sambir are interpreted. Key words: granulometric composition, petrographic composition, roundness, sorting, imbrication, braided channel, conditions of sedimentation.
