Isotopes used in dating rocks


Biogenic substances (those produced by naturally occurring life processes) can have significant variations of carbon, nitrogen and oxygen isotopes, which makes them an easier target for analysis. Food safety applications make it possible to track the country of origin of certain food products, like beef, using carbon and nitrogen isotopes. Agencies and manufacturers are also able to determine the method of feeding for livestock -- organic or conventional -- by analyzing carbon, nitrogen and sulfur isotopes. By studying carbon and oxygen isotope data, it's possible to determine where in the Mediterranean various olive oils come from, and how "natural" fruit juice products are.
