Radiometric dating measures the decay of radioactive atoms to determine the age of a rock sample.

For example: after the it forms a component of all organic compounds and is therefore fundamental to life. Libby of the University of Chicago predicted the existence of carbon-14 before it was actually detected and formulated a hypothesis that radiocarbon might exist in living matter.

By dating rocks of known ages which give highly inflated ages, geologists have shown this method can’t give reliable absolute ages.

Many geologists claim that radiometric “clocks” show rocks to be millions of years old.

Here are some of the materials that can be successfully dated using this method: Potassium-Argon Dating Potassium-Argon (K-Ar) dating is the most widely applied technique of radiometric dating.

Potassium is a component in many common minerals and can be used to determine the ages of igneous and metamorphic rocks.
