Supplementary Table 2. 40Ar /39Ar data. All Ar isotope concentrations are given as mL. K, Ca and Cl concentrations are calculated from the sample mass and the 39Ar, 37Ar and 38Ar concentrations, respectively. Note that the isotope data (but not the full stepheating details) of three ‘pure’ mica samples were published by Montemagni et al. (2020).
