Definition:
A sedimentary bed or lamina or sequence of laminae (thin layers) deposited in a
body of silt or still water within a year's time. Usually refers to glacial
varves resulting from seasonally deposited meltwater streams in a glacial lake
or other body of still water. Counting the varves have been used to measure
glacial deposits.
