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.
