Main article: In a system where carbon is readily exchanged throughout the cycle, the ratio of carbon to other carbon isotopes should be the same in a living organism as in the atmosphere. Pre-treatment seeks to remove from the sample any contaminating carbon that could yield an inaccurate date. Dating material from one location gives date information about the other location, and the dates are also used to place strata in the overall geological timeline. By knowing how much carbon 14 is left in a sample, the age of the organism when it died can be known. Volcanic eruptions eject large amounts of carbon into the air.
