  1. N is number of dated zircon crystals; ρsi spontaneous/induced track densities (×105 tracks/cm2); N s/N i is number of counted spontaneous/induced tracks; ρd dosimeter track density (×105 tracks/cm2); N d number of tracks counted on dosimeter; P2) probability obtaining chi-square value (χ2) for n degree of freedom (where n is number of crystals −1); age ± 1σ is central age ± 1 standard error; Comp. 1 and 2: different age components in samples; MTL mean track length; SD standard deviation of track length distribution; N (l) number of horizontal confined tracks
