The 40Ar/39Ar dating method offers a significant advantage over the conventional K-Ar dating technique, because potassium and argon are. So, now the rock sample to be dated contains not only the argon-40 that. The K-Ar dating method utilizes the decay of the naturally-occurring radioactive isotope of potassium, 40K, into an isotope of the noble gas, argon (i.e., 40Ar). It is based on the fact that potassium-40 (40K) decays into. This dating method is based upon the decay of radioactive potassium-40 to radioactive argon-40 in minerals and rocks potassium-40 also decays to calcium-40.
