| 摘 要： | 同位素地质年代学的各种定年方法都有其特定的测定对象（矿物或全岩）和适用范围，致使许多金属矿床难以进行年龄测定.为解决此难题，建立了流体包裹体40Ar/39Ar定年方法，经过30年的探索发展和不断改进完善，已广泛应用于热液矿床、变质岩和石英脉的形成年龄测定，甚至成功应用于松辽盆地深层天然气成藏年龄研究.在详细介绍流体包裹体提取技术和气体纯化技术的基础上，着重总结我们团队运用流体包裹体40Ar/39Ar定年技术在热液矿床和天然气藏形成年龄研究方面取得的重要成果，以及气体混合线的概念及其年龄意义.

Fluid Inclusion 40Ar/39Ar Dating Technique and Its Applications |
| |
| Abstract: | Various isotope geochronometers have their specific dating objects (minerals or whole rocks) and age ranges.It is difficult to date the ages of hydrothermal deposits.To solve this problem, the 40Ar/39Ar progressive crushing technique to date the ages of fluid inclusions is established.This technique has been improved and developed for thirty years, widely applied to determine the forming ages of hydrothermal deposits, metamorphic rocks and quartz veins, as well as the natural gas fields in deep Songliao Basin.In this article, the experimental techniques of fluid inclusion extraction and gas purification are introduced in detail, followed by the important applications in hydrothermal deposits and gas/oil fields as illustrations of 40Ar/39Ar dating by the stepwise crushing technique.The gas-mixing patterns yielded by crushing are also discussed. |
