  1. Ages were calculated using zeta calibration method (Hurford and Green 1983), glass dosimeters CN-5 and CN-2 (for apatites and zircons, respectively), and zeta values of 329.8 ± 7.1 (apatite) and 123.6 ± 2.1 year/cm2 (zircon)
  2. N number of dated apatite crystals, ρ s (ρ i ) spontaneous (induced) track densities (×105 tracks/cm2), N s (N i ) number of counted spontaneous (induced) tracks, ρ d dosimeter track density (×105 tracks/cm2), N d number of tracks counted on dosimeter; P(χ2) probability obtaining Chi-square value (χ2) for n degree of freedom (where n = no. of crystals − 1), Age ± 1σ central FT age ± 1 standard error (Galbraith and Laslett 1993), MTL mean track length, SD standard deviation of track length distribution, N(L) number of horizontal confined tracks measured, Dpar average etch pit diameter of fission tracks, AFT apatite fission track, ZFT zircon fission track
