Glaciomarine deposits

Status Code: Index Level
Age range: Pleistocene Epoch (QP) — Pleistocene Epoch (QP)
Lithological Description: Glaciomarine deposits are sediments, glacial in origin, deposited in marine waters. Fine-grained (silt and clay) deposits of subtidal sea-bed environments may or may not contain marine macro/micro fauna and may have been deposited from suspension in cold freshwater plumes (fed by meltwaters) within saline waters. Such deposits have a high clastic content derived from glaciers. Dropstones from floating ice are common. Coarse-grained deposits (sand and gravel) are present as intertidal beach and subtidal (shoreface) deposits. Synonym: glacimarine deposits. Variable lithology.
