In glacial environments varve sequences are used to establish time lines for such things as deglaciation or the repopulation of regions by organisms following deglaciation.
Varve sequences allow us to fix very precisely in varve years the age of any fossil or sediment feature found in the varves or the varve age of any event that may be tied to the varve sequence.
