摘　　要：磷灰石裂变径迹分析是建立在238U裂变辐射损伤效应基础上的一种低温热年代学技术,依据退火特性及其影响因素,建立起反应温度历史的时间—温度函数关系。早期主要应用于含油气盆地的热史模拟,在此基础上逐渐拓展到造山带的隆升、剥蚀及再沉积作用研究。近10年来,又被广泛应用于成矿作用研究和断层作用研究(断层形成年龄等)。在磷灰石裂变径迹分析的应用过程中,应尽可能同时结合其他几种方法,并注意裂变径迹的热重置问题。Based on radiation injury effect of 238U fission, apatite fission track analysis is a kind of low temperature thermochronology technology. The relationship responding the thermal history between time and temperature can be built according to annealing and its affecting factors. At the beginning stage apatite fission track is mainly used for modeling of thermal history. And then it is gradually used in the study on orogenic belt uplift, erosion, and redeposition including height and rate of uplift, thickness and rate of erosion. During the recent ten years, it has been widely used in studying mineralizing including metallogenic epoch, temperature, period, basin range coupling, etc., and faulting such as timing for faults. To make more effective apatite fission track analysis should be applied by combining with the application of other methods and fluid inclusion, and the question of thermal reset should be paid attention.
