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; ρd, dosimeter track density (×10⁵ tracks cm²); Nd, number of tracks counted on dosimeter; P(χ²), probability obtaining Chi square (χ²) value for n degrees of freedom (where n is number of crystals minus 1); age ± 1σ is central age ± 1 standard error (Galbraith and Laslett 1993); ages were calculated using zeta calibration method (Hurford and Green 1983); glass dosimeter CN-2; hr, host rock; dz, damage zone; fc, fault core
