B - Argon-Argon Dating. Argon-argon (or 40 Ar 39 Ar) dating is a radiometric dating method invented to supersede potassium-argon (K-Ar) dating in accuracy.
This is the first step toward an enhanced K-Ar dating method in which both parent (40K) and daughter (40Ar) nuclides are measured in the same sample aliquot. Radiometric dating methods estimate the age of rocks using calculations based on the decay rates of radioactive elements. Uranium decays to lead by a complex series of steps..
