Carbon-14, Radiometric Dating - CSI Carbon dating is used to determine the age of biological artifacts up to 50,000 years old. This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils (like those of the dinosaurs alleged to be millions of years old).

6. How long is material radioactive? carbon-14. (4) Geological dating of igneous rocks Certain elements with very long half-lives can be used to date the geological age of igneous rocks and even the age of the Earth. has a half-life of 1.3 x 10 9 years. It decays to form .; If the argon gas is trapped in the rock, the ratio of potassium-40 to argon-40 decreases over time and the ratio can be used to date the age of rock formation i.e. from.

Dating - Rubidium–strontium method | Britannica.com Dating - Rubidium–strontium method: The radioactive decay of rubidium-87 (87Rb) to strontium-87 (87Sr) was the first widely used dating system that utilized the isochron method. Rubidium is a relatively abundant trace element in Earth’s crust and can be found in many common rock-forming minerals in which it substitutes for the major element potassium.
