Glaciolacustrine deposits

Sediments in the bedload and suspended load are carried into lakes and deposited.

Sediments carried in the bedload of a stream, mostly sands and gravels, are deposited in deltas that form at the edges of lakes.

These are the principal deposits during the winter because of lack of melting of the glacier so the stream has a reduced discharge therefore carrying less coarse material.

These sediments normally consist of fine-grained rhythmites that are laid down in layers known as varves or varvites.

Sedimentation in deltas also occurs in rhythmic patterns as in the lake deposits, but they are thicker and contain coarse-grained materials instead of just silt and clay.
