Because it is present within the atmosphere, every rock and mineral will have some quantity of Argon.

Argon can mobilized into or out of a rock or mineral through alteration Ar and potassium, there is not a reliable way to determine if the assumptions are valid.

On the other hand, the abundance of argon in the Earth is relatively small because of its escape to the atmosphere during processes associated with volcanism.

The potassium-argon dating method has been used to measure a wide variety of ages.

Step-heating is the most common way and involves either a furnace or a laser to uniformily heat the sample to evolve argon.

For example, to determine the amount of reactor produced Ar ratio of the glass is then measured in the mass spectrometer to determine the correction factor that must be applied to the rest of the samples in that irradiation.

Ca F is also routinely irradiated and measured to determine the Ar technique relies on ratios instead of absolute quantities, we are able to extract and measure multiple aliquots of argon from a single sample.

The potassium-argon age of some meteorites is as old as 4,500,000,000 years, and volcanic rocks as young as 20,000 years old have been measured by this method.

The isotopes the KAr system relies on are Potassium (K) and Argon (Ar).

Argon loss and excess argon are two common problems that may cause erroneous ages to be determined.
