Identification Type Lithofacies
Name Glacial varves
Distinguishing Features
Description Lithofacies comprising annually laminated sequences of sand, silt or clay deposited in a glacially-influenced lacustrine (or marine) setting.

Repetitively laminated variations in grain size from sand to clay, representing seasonal variations in glacial melt-water cycles and sediment transport; dropstones may be present if deposited in an ice-contact setting.
