摘　　要：低温热年代学方法已被广泛地应用于地学领域,尤其是磷灰石/锆石(U-Th)/He、磷灰石/锆石裂变径迹(AFT/ZFT)方法,由于该方法封闭温度较低,对晚新生代构造演化、地形地貌变化等地表过程非常敏感,具有其他地质年代学方法无法比拟的优势。随着这种方法的发展,目前可准确测定年轻火山岩年龄低至千年左右。该方法还推动了近十年来造山带演化和地貌演化研究的热潮,它不仅限定了剥露抬升阶段和速率,还为新的模拟手段提供了基础数据。Low temperature thermochronology methods have been widely used in the field of geology,especially the apatite/zircon(U-Th)/He,apatite/zircon fission track(AFT/ZFT)methods,due to closure temperature is low,and it is very sensitive to surface processes such as late Cenozoic tectonic evolution,topographic changes,and geomorphology,volcanic age,etc.,and has incomparable advantages over other geochronological methods.With the development of the method,young(~ka)volcanic rocks can be dated accurately.This method has also promoted the upsurge of research on orogenic belt evolution and geomorphological evolution over past decade.It not only calculated exhumation and uplift rate,but also provides basic data for new modeling.
