These reactor produced isotopes of argon must be corrected for in order to determine an accurate age.

The isotopes the KAr system relies on are Potassium (K) and Argon (Ar).The abundance of Ar is unlikely to provide the age of intrusions of granite as the age typically reflects the time when a mineral cooled through its closure temperature.However, in a metamorphic rock that has not exceeded its closure temperature the age likely dates the crystallization of the mineral.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.
