Category: Earth Science Published: July 10, Geologists do not use maximum age radiocarbon dating 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.

Because of the short length of the carbon half-life, carbon dating is only accurate for items that are thousands to tens of thousands of years old.
