Acquisition of an Excimer-Laser Based Laser Ablation ICP-MS System

该合同为获得基于准分子激光的激光烧蚀ICP-MS系统提供了资金，该系统针对流体和熔体包裹体的分析进行了优化。包裹体代表了生长过程中包裹在晶体周围的液体或熔体的小样本，并提供了关于矿物形成过程中化学环境的最直接证据。该仪器将用于从各种地质环境（包括岩浆-热液矿床、地热和火山系统、变质环境和深部地壳和地幔）中获得单个流体和熔体包裹体的主要、次要和微量元素组成的定量分析。该实验室将对所有需要对流体或熔体内含物进行定量化学分析的研究人员开放。

0420849BodnarThis award provides funding to acquire an excimer-laser based laser ablation ICP-MS system optimized for the analysis of fluid and melt inclusions. The inclusions represent small samples of fluid or melt that surrounded a crystal during growth, and provide the most direct evidence available concerning the chemical environment during mineral formation. The instrumentation will be used to obtain quantitative analyses of major, minor and trace element compositions of individual fluid and melt inclusions from a wide variety of geologic environments, including magmatic-hydrothermal ore deposits, geothermal and volcanic systems, metamorphic environments and the deep crust and mantle. The laboratory will be available to all workers whose research requires quantitative chemical analysis of fluid or melt inclusions.
