Zircon is one of the most useful minerals used to unravel the Earth’s history recorded in rocks. After the success of etching fission tracks in zircon (Fleischer et al. 1964; Naeser 1969; Krishnaswami et al. 1974), early studies focused primarily on dating young volcanic horizons for stratigraphic purposes (e.g., Naeser et al. 1973; Hurford et al. 1976; Seward 1979; Gleadow 1980; Kowallis et al. 1986; Kohn et al. 1992). Subsequently, fission-track analysis of zircon has been extensively employed, along with other radiometric dating methods, such as U/Pb and (U-Th)/He techniques...
