Absolute ages of carbon unless the conceptual and there are two methods half-life is a sample. Isotopes are different versions of the same element e. That is, at some point in time, an atom of such a nuclide will undergo radioactive decay and spontaneously transform into a different nuclide. Argon is a noble gas, which means that it is nonreactive and would not be a part of the initial formation of any rocks or fossils.

The technique has potential applications for detailing the thermal history of a deposit. This field is known as thermochronology or thermochronometry. Any argon found in a rocks or fossils therefore has to be the result of this kind of radioactive decay. The temperature at which this happens is known as the closure temperature or blocking temperature and is specific to a particular material and isotopic system.
