SD standard deviation
Track densities (Rho) are as measured (×10⁵ tracks/cm²); number of tracks counted (N) shown in brackets. Chi-sq. P (%), probability obtaining Chi-square value for n degree of freedom (where n = no. crystals-1); Disp., Dispersion, according to Galbraith and Laslett (1993). Central ages calculated using dosimeter glass: CN2 with ζ_CN2 = 124.7 ± 2.2 for zircon. Modeled detrital zircon fission track age populations were identified within the bulk single grain age distributions by the PopShare computer software (Dunkl and Székely 2002) using a Simplex algorithm and assuming Gaussian distribution for the populations
