Glaciolacustrine Deposits

 

the bottom sediments of lake basins deposited by glacial meltwater flowing along the margin of a glacier or among fields of dead ice. The deposits consist of sorted, predominantly stratified, formations of varying composition, from coarse sands (riparian facies) to clays. Varved clays are most characteristic of such deposits.

Generally, the concentration of eU was lower in glaciolacustrine deposits and carbonate-rich till; however, patches with higher eU concentration occurred within these deposits as well.

The bedrock surface in Estonia is strongly dissected by deep ancient valleys (Tavast & Raukas 1982), which, according to their geological structure, can be subdivided into valleys filled mainly with glaciofluvial deposits of the last glaciation, valleys filled mainly with glaciolacustrine deposits of the last glaciation, valleys with one till bed with underlying or covering glaciofluvial and glaciolacustrine deposits, valleys of a complicated structure with more than one till bed and accompanying glaciofluvial and glaciolacustrine deposits.
In addition to till, there are four other major types of glacial deposits: a) sediment flow deposits and ice-slope colluvium, 2) outwash or glacial fluvial deposits, 3) glaciolacustrine deposits, and 4) glacioeolian deposits.
Transport of finer particles of glaciolacustrine deposits from upslope decreased during its deposition, and so did the sedimentation rate.
