ABSTRACT
Glaciomarine sediments constitute the bulk of modern and ancient glacial deposits in relation to both their total volume and areal distribution. However, in spite of their widespread occurrence, there is no consensus on views of the origin of these sediments, particularly their structural characteristics and depositional environments. This chapter attempts to explain these problems in the relation to the proximal facies of glaciomarine deposits. Instructive evidence seems to be available in sections of glaciomarine deposits of the Vistulian (Weichselian) Glaciation in the northern part of the lower Vistula region. The base of the lower till unit is concordant with the bedding of the underlying sandy-silty sediments. This sedimentary relationship can also be traced in the fining-upward sequence of the underlying sediments and in the sporadic pebbles occurring in the overlying till. The silt-sand laminae give rise to planes of parting lineations that are enlarged during weathering of the deposit.
