Water-glacial (fluvioglacial, glaciofluvial) deposits (f) - the genetic type of glacial deposits associated with the melting [1] of retreating or advancing glaciers [2] [3] . They are mainly represented by sands [4] and coarse clastic soils [5] , quartz prevails in the composition. Badly sorted [6] . They do not contain plant residues [2] . Fluvioglacial deposits reach considerable thickness in the areas of ancient lake basins [7] .
Water-glacial sediments stand out under the bottom moraines, above them and beyond the outer boundary of the melting glacier [8] . Some researchers refer to lake-glacial deposits as fluvioglacial [9] [10] .
They are divided into frontal, frontal and prefrontal. Frontal fluvioglacial deposits form in the body of the glacier [2] . Alluvial deposits are very rarely associated with fluvioglacial deposits (compared with alluvial deposits) [5] .
Landforms
Fluvioglacial sediments carried by the meltwater of the glacier at its base [11] form sand fields - zander [2] , dried valleys [12] and terraces [13] . Landscapes formed by fluvioglacial deposits depend on the composition and genesis of the glacial relief [3] .
- Ozovy deposits - are connected only with activity of flows of thawed glacial waters
- Kama deposits - formed by the flows of melt glacial water and water accumulated in the body of the glacier [14]
