Acquisition of a Fourier-Transform Infrared Spectrometer for igneous petrology, volcanology, and geobiology research

1258940 KelleyThis仪器/设备补助金支持购买傅里叶变换红外（FTIR）光谱仪和岩相显微镜，用于在微观空间尺度上对天然玻璃，矿物和岩石中的挥发性和有机物质进行原位非破坏性分析。该仪器将补充罗得岛大学海洋学研究生院现有的微观分析工具，并支持具体研究，包括：1）调查挥发物（H2O和CO2）在板块构造周期和地幔熔融中的作用，2）研究地球中碳的行为和通量？的上地幔，3）在冰川成层火山岩浆/冰/融水相互作用的研究，4）挥发物在海底爆发火山作用的研究，和（5）在地球上的生物和地质过程的相互作用的调查？的近地表环境。 该仪器将为URI-GSO的研究生调查提供服务，项目研究员计划开展推广活动，使罗得岛地区的科学教师了解现代地球科学研究的工具。***

1258940 KelleyThis EAR/Instrumentation and Facilities grant supports acquisition of of a Fourier Transform InfraRed (FTIR) spectrometer and petrographic microscope for in situ, non-destructive analysis of volatile and organic species in natural glasses, minerals, and rocks at microscopic spatial scales. This instrument will complement existing micro-analytical tools at the Graduate School of Oceanography (GSO), University of Rhode Island (URI) and support specific studies including 1) investigations of the role of volatiles (H2O and CO2) in plate tectonic cycles and mantle melting, 2) study of the behavior and fluxes of carbon in the Earth?s upper mantle, 3) research on magma/ice/meltwater interactions at glaciated stratovolcanoes, 4) studies of the role of volatiles in submarine explosive volcanism, and (5) investigations of the interplay of biological and geological processes in Earth?s nearsurface environments. The instrument will serve graduate students investigations at URI-GSO and the PIs plan outreach activities to expose regional Rhode Island science teachers with tools of modern geoscience research. ***
