Fission-track (FT) thermochronology is a low-temperature dating technique utilizing the damage property produced by uranium fission decay. As the advanced researches of annealing behavior, and laboratory annealing models, this technique, especially apatite fission-track, has become an important measure to constrain the thermal history of sedimentary basin. Among three main apatite fission-track annealing models proposed by Laslett et al.(1987), Crowley et al.(1991) and Ketcham et al.(1999), respectively, the last one is the most significant and widely-applied annealing model, which integrated the influence of time, temperature and chemical composition to various types of apatite, together using the c-axis projected track-length and Dpar.
