FLUID INCLUSIONS IN HALITE: CLUES TO THE HISTORY OF SEAWATER

在之前的工作中，已经开发了从岩盐岩、中新世、二叠纪和硅系海相蒸发岩的流体包裹体中提取和分析流体的技术。中新世岩盐包裹体表明海水成分与今天相似；然而，在显生宙蒸发岩中发现了Br/K浓度的变化。目前的计划包括调查其他地点的流体，完善我们对海水蒸发化学途径的理解，并开发解释包裹体流体组成的模型。除了了解海水演变这一重要目标之外，研究结果的可能应用还可用于勘探有价值的盐矿和利用盐层作为核废料储存库。

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.
