Fission-track (FT) analysis has developed into one of the most useful techniques used throughout the geologic community to reconstruct the low-temperature thermal history of rocks over geological time. The FT method is based on the accumulation of narrow damage trails (i.e., fission tracks) in uranium-rich mineral grains (e.g., apatite, zircon, titanite) and natural glasses, which form as a result of spontaneous nuclear fission decay of 238U in nature (Price and Walker 1963; Fleischer et al. 1975). The time elapsed since fission tracks began to accumulate is estimated by determining the density of accumulated tracks in a...
