In Prior work, techniques have been developed for the extraction and analysis of fluid from fluid inclusions in halite, miocene, permian and silirian marine evaporites have been studied so far. Miocene halite inclusions indicate sea water compositions similar to today; however, variations in Br/K concentrations have been identified throughout phanerozoic evaporites. Plans now include investigation of fluids from additional sites, refinement of our understanding of chemical pathways involved in evaporation of sea water and develop models for interpreting the composition of inclusion fluids. Beyond the important goal of understanding the evolution of sea water, possible application of results may apply to exploration of valuable saline deposits and use of salt beds for nuclear waste repositories.

在先前的工作中，已经开发了用于 从岩盐中的流体包裹体中提取和分析流体， 研究了中新世、二叠纪和志留纪海相碳酸盐岩 迄今 中新世岩盐包裹体指示海水成分 类似于今天;然而，Br/K浓度的变化 在整个显生宙的陨石中都有发现。 计划现在 包括对来自其他地点流体进行调查， 我们对蒸发过程中的化学途径的理解 并开发解释海水成分的模型 包裹体流体。 超越理解的重要目标 海水的演变，可能的应用结果， 适用于有价值的盐矿勘探和盐的利用 用于核废料储存库的床。
