Apatite fission-track data.
|Sample number||Deposition (Ma)||n||Age range (Ma)||ρs (10−5 cm−2)||Ns||ρi (10−5 cm−2)||Ni||ρd (10−5 cm−2)||P(χ2)||Central Age (Ma)||±1 σ||Minimum age (Ma)||±1 σ|

Note: Samples were counted dry with a BX51 Olympus microscope at 1250× magnification. Central and minimum ages were calculated with the RadialPlotter program of Vermeesch (2009), using a zeta value of 214.63 ± 18.5 and the IRMM540R dosimeter glass. ρs: spontaneous track density; ρi: induced track density; ρd: track density of the fluence monitor.
