摘　　要：矿物裂变径迹技术是一种低温热史及年代学测定技术,广泛应用于含油气盆地热史分析、沉积物来源、造山带隆升剥蚀、地质年代学测定等方面的研究。近年来,磷灰石裂变径迹在研究造山带构造隆升速率方面取得了大量成果。笔者在结合前人研究成果基础上,分别介绍了利用裂变径迹反演热史、裂变年龄和矿物对-封闭温度法确定构造隆升速率的原理、方法和应用,并分析其优缺点,指出应用磷灰石裂变径迹研究构造隆升速率时应该注意的问题。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.
