Geologists do not use carbon-based radiometric dating to determine the age of rocks. Carbon dating only works for objects that are younger than about 50, years, and most rocks of interest are older than that. Carbon dating is used by archeologists to date trees, plants, and animal remains; as well as human artifacts made from wood and leather; because these items are generally younger than 50, years. Carbon is found in different forms in the environment — mainly in the stable form of carbon and the unstable form of carbon

By comparing the amounts of uranium and lead present in a rock sample, its approximate age can be found.
