Apatite Fission Track Dating Method and Its Application
Apatite fission track is the most common low-temperature thermochronology dating method in re-cent years,which records the thermal history information of rocks at 60 ℃~120 ℃ and reflects the cooling his-tory of shallow surface.Based on the published literature at abroad,this paper mainly introduces the following aspects:(1)the experiment principle of apatite fission track;(2)the processing software(TrackKey and HeFTy)and interpretation of apatite fission track data;(3)the geological application of apatite fission track,in-cluding the studies of the mountain exhumation,paleogeomorphology,the age of fault activity and basin evolu-tion.Comparing with other traditional isotopic dating methods,apatite fission track is one of the most effective methods to study the low temperature thermal history information of geological bodies because of its low annealing temperature,high temperature sensitivity and accuracy.
