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对海洋岩石石英脉中的流体包裹体进行化学分析。 将使用原子吸收分光光度法通过常规压碎/浸出分析来分析现有岩石上特征良好的均匀流体包裹体群。 然后可以将该数据与从活跃温泉中采样的热液端构件进行比较。 %%% 流体包裹体研究提供了有关热液系统温度和流体盐度的重要信息。 之前没有尝试直接确定夹杂物中流体的化学成分，这些信息对于热液系统的完整表征非常重要。 能够将化石系统中包裹体的流体成分与目前活跃的海底系统的成分进行比较将非常有用。 该项目获得的数据可能会开辟新天地。
