Once the source of sediment is cut off, the link with the present is severed, and unless we could find some other method to place an absolute date on one of the varves, the only thing we can tell from them is the difference in age between two varves, but not how old either of them is. We can count back thousands or tens of thousands of years, but as we shall see in later articles this is only a short span of time in proportion to the much longer history of the Earth.We introduced the idea of cross-dating in the article on dendrochronology.Given such a situation, there is no difficulty in principle in finding the age of any varve; we just start from the one that was deposited this year and count backwards.(In practice there may be technical difficulties, but the principle is straightforward enough.)

25 cm in length, including a 1.5 cm overlap with neighbouring subsamples.
Since then the definition of a varve has been extended so that it can be used to describe any layer which is deposited annually, the varves in proglacial lakes being only one example.
