argón-39

argón-40/argón-39

A radiometric dating method based on the changing ratio of argon-40 to argon-39 with the passage of time in volcanic rock or ash. This technique was derived from potassium-argon dating. The argon-40/argon-39 method is usually more accurate than potassium-argon dating and doesn't require as large a sample.
