The objective of this project is to directly chemically analyze fluid inclusions from quartz veins from oceanic rocks. Well-characterized, homogeneous fluid inclusion populations on rocks already in hand will be analyzed by conventional crush/ leach analysis using atomic absorption spectrophotometry. This data can then be compared to hydrothermal end members sampled from active hot springs. %%% Fluid inclusion studies provide important information about the temperature of hydrothermal systems and about the salinity of the fluid. There has been no previous attempt to determine directly the chemical composition of the fluid trapped in the inclusion and such information is important to a complete characterization of the hydrothermal system. It would be extremely useful to be able to compare fluid compositions in inclusions in fossil systems with compositions of presently active seafloor systems. The data to be obtained in this project could break new ground.

该项目的目标是直接化学 分析大洋岩石中石英脉中的流体包裹体。 特征良好的，均匀的流体包裹体群体 现有的岩石将通过常规破碎/ 使用原子吸收分光光度法进行浸出分析。 然后可以将该数据与热液端员进行比较 取自活跃的温泉 %%% 流体包裹体研究提供了重要信息 热液系统的温度， 流体的盐度。 以前没有人试图 直接测定流体的化学成分 这些信息对一个人来说很重要， 热液系统的完整表征。 它将 非常有用的是能够比较流体组成， 化石系统中的包裹体， 主动海底系统。 本研究中获得的数据 项目可以开辟新天地。
