Apatite Fission Track Dating Method and Its Application
the apatite fission track has been widely used in the geological field to record the cooling process of shallow surfaces due to its low annealing temperature(60 ℃～120 ℃).By summarizing previous researches,this article introduc-es the experimental principle of apatite fission track,the processing and interpretation of experimental data,and focuses on the application of this method in geological evolution processes,including the process of ore deposit exhumation,the geological evolution of orogenic belts,the basin evolution,the paleogeomorphology and the age of fault activity.Al-though this method is one of the most effective methods for studying the low-temperature thermal history information of geological bodies,there are still shortcomings in the dating process,such as the easily influenced by human factors,the unsuited measuring for low U or young geological bodies,and the longer experimental period.Therefore,in order to more accurately constrain the evolution process of geological bodies,multiple technical means still need to be combined.
