Gas Chemistry of Fluid Inclusions as a Tracer of Magmatic Contributions to Hydrothermal Systems

越来越多的证据表明，磁性气体的小输入可能是一个重要的、未被识别的参数，可以用来分类和理解其他类似的系统。天然气丰度和同位素组成的耦合分析将由来自几个可能接受磁性气体输入的矿床的流体包裹体进行，包括内华达州的Comstock和日本的Hishikari。还将分析斑岩铜和酸性硫酸盐矿床中的富气包裹体。这项研究将以来自活跃地热系统的气体和同位素分析结果为指导。这将影响我们对活动和化石热液系统的理解。

Evidence is accumulating to suggest that small inputs of magnetic gas could be an important, unrecognized parameter that might be used to classify and understand systems that are otherwise similar. Coupled analyses of gas abundances and isotopic compositions will be made of fluid inclusions from several deposits that might have received inputs of magnetic gas, including Comstock, Nevada and Hishikari, Japan. Analyses will also be made of vapor-rich inclusions from porphyry copper and acid-sulfate deposits. The study will be guided by results of gas and isotopic analyses of materials from active geothermal systems. This should impact our understanding of both active and fossil hydrothermal systems.
