The main lithological characteristics of the sands, gravels and pebbly deposits in the particular layers of the seventh terrace of the Dniester River in the investigated part of its Podillian valley have been analyzed. The texture and the granulometrical and petrographical composition of the sands, gravels and pebbly materials has been described, including the roundness of the grains and some other features. The conditions of sedimentation of the alluvial sands, gravels and pebbly deposits of the seventh terrace of the Dniester River have been reconstructed and direction of the palaeo-Dniester flow and some other features interpreted. Key words: terraces over the canyon, alluvium, granulometrical composition, petrographical composition, sandstone, aleurolite, quartz, siliceous rocks, roundness.

The main lithological characteristics of the alluvium of the sandy-gravelly bed of the sixth terrace of the Dniester river (Loyeva level) at environs of Sambir was analysed, in particular textural elements, granulometric and petrographic composition of the gravelly material (enclosing coarse sands, granules, pebbles, cobbles and boulders), its roundness, and the orientation of grains. The conditions of sedimentation of the studied alluvial sandy-gravelly bed of the sixth terrace of the Dniester river (Loyeva level) were reconstructed. Key words: granulometric composition, petrographic composition, roundness, sorting, imbrication, braided channel, depositional conditions.

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.
