| 摘 要： | ^40Ar—^39Ar测年法的出现，为同位素地质年代学开辟了一个新的领域；但过剩氩的存在、年龄谱的分析方法，又制约着地质事件的年龄解释。在介绍该方法的原理、校正、年龄谱的分析和应用及过剩氩问题等方面内容的基础上，结合阿尔金断裂研究实例，对该断裂中的新生矿物进行了^40Ar-^39Ar测年，进而确定了阿尔金断裂走滑活动的年龄。

| Abstract: | Ar-39Ar dating method sets up a new field for isotopic geochronology. Both the occurrence of excess argon and the analysis of age spectrum restrict the interpretation of geologic events. On the basis of principle,correction,analysis and application of age spectrum and the problem of excess argon,combing with the research example of Altyn Fault,the authors have 40Ar-39Ar dating using these new-born minerals and determinated the age of faulting and strike-slip activity of Altyn. |
