Carbon dating, also known as radiocarbon dating, is a method of estimating the age of carbon-bearing materials up to 60,000 years old one of the most frequent uses of radiocarbon dating is to estimate the age of organic remains from archaeological sites however, it is also used to determine ages of rocks, plants, trees, etc. Carbon dating definition, meaning, what is carbon dating: a method of calculating the age of extremely old objects by measuring the amount of a learn more. Carbon dating is based upon the decay of 14 c, a radioactive isotope of carbon with a relatively long half-life (5700 years) while 12 c is the most abundant carbon isotope, there is a close to constant ratio of 12 c to 14 c in the environment, and hence in the molecules, cells, and tissues of living organisms.
