随着近代科学的发展,各种越来越精确的测试手段也不断发展和完善,使得研究地层年代的方法有了新的进展:古地磁法、碳-14法、氨基酸法、钾-氩法、铀系法等,在第四纪年代学上发挥着越来越大的作用。 尽管这些方法各有其优点,但它们适用的年代范围都是有局限的。裂变径迹法的适用范围很宽(从几十年到几十亿年),近十多年来,它解决了许多用其它方法不易解决的地质年代问题。 本文从三个方面对裂变径迹法进行了讨论。 With the development of modern science, a variety of more and more accurate test methods have been developed and improved continuously, making new progress in the study of the age of strata: paleomagnetic method, carbon-14 method, amino acid method, potassium-argon method , Uranium system, etc., playing an increasingly important role in quaternary chronology. Although each of these methods has its own merits, there are limits to the age at which they apply. The fission track method has a wide range of applications (from decades to billions of years) and has solved many of the geochronological problems that have not been easily solved by other methods in the past decade or so. This article discusses fission track method from three aspects.
