The calibration of a glacial varve record, series, or chronology is accomplished by applying numerical or calendar ages to existing varve numbers.

Most often contamination is the result of younger material added to a sample in a particular field setting.A fossil that is significantly contaminated with younger material will produce a calibration that is too young even if a lag time might partly offset the error.In the example below, the calibration is too young because a C age reflects not only the age of ancient plant remains but also more recent contaminants.The most reliable ages are from fossils that got their carbon directly from the atmosphere.If you want accurate results, the bottom line is that the C ages are obtained and the bad apples reveal themselves.
