摘要
就地生成宇宙成因核素年代学通过宇宙射线与地表岩石反应所积累核素浓度进行测年,相较传统定年方法具有许多独特的优势,近30年来得到了迅速发展和完善,已成为第四纪研究中的主要测年方法之一。目前该方法虽然仍存在一些问题和限制,随着研究和认识的深入,其理论方法将会越来越成熟,新的核素和应用领域也将会逐步扩展。本文通过就地生成宇宙成因核素的产生机制、测年原理、影响因素等方面对该方法进行了全面的介绍,为相关学者在测年实践中的应用提供有益的指导。
The chronology of in situ cosmogenic nuclides uses the nuclides concentration for dating,which accumulated from the reaction between cosmic ray and surface rock.Compared with the traditional dating method,it has many unique advantages.It has been rapidly developed and improved in the past 30 years and has become one of the main chronology methods in the Quaternary study.Although there are still some problems and limitations in this method at present,with the further research and understanding,its theory andmethod will become more and more mature.New nuclide and application realm will also gradually expand.This article gives a comprehensive introduction to the generation mechanism of in situ cosmogenic nuclides,the principle of the chronology,and influencing factors.That will provide useful guidance for the application in practice of relevant scholars.
