Mineral fission track is a kind of measurement technology for low temperature thermal history and chronology,which is widely used in analysis of oil and gas basin thermal history,the source of sediments,the uplift and denudation of orogenic belt,the geochronology measurement and so on.In recent years,apatite fission track has got lots of achievements in the tectonic uplift rates study of orogenic belt.Based on previous fission track analysis researches,this article respectively introduces the use of fission track to invert thermal history,fission age and minerals to closed temperature method to determine the tectonic uplift rates of principle and method and application.At the same time the paper analyzes its advantages and disadvantages,pointing out the problems need to be considered when applying apatite fission track to study tectonic uplift rates.
