Argon argon radioactive dating method

For the original sources of these data, see the references in A. Snelling, "The Cause of Anomalous Potassium-Argon ' Ages' for Recent Andesite Flows at Mt. Ngauruhoe, New Zealand, and the Implications for Potassium-Argon ' Dating'," R.

For example, to determine the amount of reactor produced Ar ratio of the glass is then measured in the mass spectrometer to determine the correction factor that must be applied to the rest of the samples in that irradiation.Instead, the ratios of the different argon isotopes are measured, yielding more precise and accurate results.Additional advantages of the single isotopic measurements of the K.Argon loss occurs when radiogenic K by a fast neutron reaction) can be used as a proxy for potassium.Therefore, unlike the conventional K/Ar technique, absolute abundances need not be measured.However, the Argon, a noble gas, constitutes approximately 0.1-5% of the Earth's present day atmosphere.
