Abstract:
Fast neutron irradiation of potassium-bearing minerals produces artificial 3 9 Ar. Mass spectrometric measurement of the 3 9 Ar/4 0 Ar ratio allows to calculate a geological age. Stepwise degassing of the sample yields insight into its history. As an example, analysis of a single hornblende from the Valtellina (Italian Alps) reveals an unexpected pre-Alpine history of that region.
