These levels correspond to glaciolacustrine deposits
. Distorted strata were observed at depth ranges of 10.7-11.4, 15-16 m, and 18.9-20.4 m.
Those valleys, eroded into the bedrock by glaciers and their meltwaters, are usually filled with glaciofluvial or glaciolacustrine deposits
or tills in combination with glacio-aquatic deposits (Raukas & Kajak 1997).
Sandy soils originate from glaciofluvial and glaciolacustrine deposits
that are wide-spread in north-eastern Germany.
The Vasavere buried valley is filled with glaciofluvial and glaciolacustrine deposits
, mainly with sand and silt, partly with the mixture of gravel (Figs.
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.
The sedimentary sequences described from the WM and OM exposures are interpreted as a deglacial sequence of till overlain by glaciolacustrine deposits
. This interpretation is based on the massive, clay-rich characteristic of the diamicton that contains erratic stones and is similar to till mapped in northwest Ohio (Larsen et al.
Layer 1 (1-3 m thick) corresponds to Upper Quaternary deposits: marsh (bog), alluvial and glaciolacustrine deposits
, basal and marginal till (Report ...
The fragments of Dictyonema shale crushed by continental glacier are distributed in the till of the klint zone, as well as in glaciolacustrine deposits
and talus of the klint.
On the seismic profiles from the central, deeper part of the lake, an unstable reflector appears on top of the signal interpreted as glaciolacustrine deposits
The diversity of soils is greatest on glacigenic and glaciolacustrine deposits
, with the highest variety in granulometric composition (sand, loamy sand, loam, silt, clay).
