Radiocarbon dating is an important tool for the determination of the age of many samples and covers the time period of approximately the last 50, years. We can use radiocarbon dating to estimate the age of a wide variety of carbon-containing materials. Both organic or inorganic materials at the Earth's surface and in the oceans form in equilibrium with atmospheric carbon
Category: Earth Science Published: July 10, Geologists do not use carbon-based radiometric radiocarbon dating years 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 has a half life of years, meaning that years after an organism dies, half of its carbon atoms have decayed to nitrogen atoms.
Similarly, years after an organism dies, click here one quarter of its original carbon atoms are still around. 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.
