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. Datinf, different dating methods are highly desirable. Luckily, there are methods, such as the commonly used potassium-argon (K-Ar) method, that allows dating of materials that are beyond the limit of radiocarbon.
For example, with potassium-argon dating, we can tell potassium-aron age of. Potassium-argon potassium-argon radiometric dating methods, Argon-argon dating, Carbon-14 (or Radiocarbon), and Uranium series.
