Fluid inclusions in subseafloor hydrothermal quartz can be a good tool for reconstructing ancient seawater composition through the Earth history because it generally contains seawater component. In this study, we geologized in Tertiary submarine volcanoes to collect samples of hydrothermal quartz. An analytical system was newly developed to extract fluid from the quartz, which was applied to the collected samples. As a result, Tertiary seawater CO_2 concentration that has been independently estimated from other method was reconstruct by using this methods. It is therefore demonstrated that this method is quite useful tor reconstructing ancient seawater composition.

海底热液石英中的流体包裹体可以成为重建地球历史中古代海水成分的良好工具，因为它通常含有海水成分。在这项研究中，我们对第三纪海底火山进行了地质研究，以收集热液石英样本。新开发了一种分析系统，用于从石英中提取流体，并将其应用于收集的样品。结果，利用该方法重建了从其他方法独立估算的第三纪海水CO_2浓度。因此表明该方法对于重建古代海水成分非常有用。
