真空击碎提取流体包裹体40Ar/39Ar定年技术经过不断的技术创新和设备升级，目前已成功应用于热液矿床、高级变质岩和油气成藏40Ar/39Ar年代学研究。然而，前期的研究偏重于拓展其应用领域，而基础理论研究（如共生矿物40Ar/39Ar定年对比研究和其他同位素定年方法之间的对比研究）相对薄弱。本项目拟通过对具有丰富共生矿物组合的华南钨锡矿床（石英、锡石、黑钨矿、辉钼矿、云母、长石等矿物），进行精细的同位素年代学研究。流体包裹体的成分，代表了成矿成藏等地质流体的组成，是金属矿床和油气藏成因研究的基本资料。建立高灵敏度的四极质谱流体包裹体气体成分测试平台，开展流体包裹体气体成分研究有助于了解真空击碎不同阶段释出气体成分与含量的差异，判断流体的K含量，获取真实成矿流体信息，分析其流体源区，合理解释40Ar/39Ar年代学数据。

In the recent years, 40Ar/39Ar progressive crushing has been successfully applied to determine the fluid ages of hydrothermal deposits, UHP metamorphism eclogites and natural has hydrocarbon accumulations with the continuous development of the technique innovation and apparatus upgrade. However, previous studies focused on expanding the application of the 40Ar/39Ar dating of fluid inclusions, the foundation studies are relative weak. The aim of this study is to conduct a detailed geochronology investigation of W-Sn deposits in south China based on their rich coexisting minerals such as quartz, cassiterite, wolframite, molybdenite, mica, feldspar and so on. The composition of the fluid inclusion can provide basic information of fluid origin for the study of the genesis of ore deposits and oil-gas reservoir. High resolution gas component analyses of fluid inclusion using a Quadrupole Mass Spectrometer combined with crushing apparatus can give helpful insight into the gas released behaviours during progressive and help us to explain the fluid inclusion 40Ar/39Ar age more reasonably.
