项目摘要

0321004LoubereThis Major Research Instrumentation (MRI) grant provides partial support for the purchase of an stable isotope ratio mass spectrometer (SIRMS) equipped with specialized inlet systems for carbonate and water analysis and for gas chromatography. This facility will support research and instruction at Northern Illinois University in three areas: (a) aqueous, carbonate and silicate geochemistry, (b) biogeochemistry and (c) geomicrobiology. The facility will accommodate a wide variety of users and will provide rapid, easy, automated sample analyses. NIU faculty including Paul Loubere, Melissa Lenczewski and Gene Perry will use the SIRMS for stable isotopic studies of silicates, carbonates, natural waters, organic matter and specific organic molecules. Research areas to be addressed include mineral equilibria; petrogenesis of rocks from North America, Central America and Antarctica; mineral precipitation and diagenesis; the marine carbon cycle; the role of tropical oceans in climate change; timing and causes of glaciation at high latitudes; the elemental fluxes through volcanic arcs; groundwater geochemistry including the degradation of anthropogenic compounds; and topics in geobiology. The facility will also benefit scientists at other regional mid-west institutions including Illinois State, Southern Illinois and The Field Museum of Natural History in Chicago. The facility will increase collaborations among a broad range of researchers and their students at a number of these institutions. ***

0321004 LoubereThis重大研究仪器（MRI）赠款提供部分支持购买一个稳定的同位素比质谱仪（SIRMS）配备了专门的入口系统，用于碳酸盐和水的分析和气相色谱。该设施将支持北方伊利诺伊大学在三个领域的研究和教学：（a）水、碳酸盐和硅酸盐地球化学，（B）地球化学和（c）地球微生物学。该设施将容纳各种各样的用户，并将提供快速、简便、自动化的样品分析。包括Paul Loubere，Melissa Lenczewski和Gene佩里在内的NIU教师将使用SIRMS对硅酸盐，碳酸盐，天然沃茨，有机物和特定有机分子进行稳定同位素研究。涉及的研究领域包括：矿物平衡;北美洲、中美洲和南极洲岩石的岩石成因;矿物沉淀和成岩作用;海洋碳循环;热带海洋在气候变化中的作用;高纬度冰川作用的时间和原因;通过火山弧的元素通量;地下水地球化学，包括人为化合物的降解;以及地球生物学专题。该设施还将使其他中西部地区机构的科学家受益，包括伊利诺斯州、伊利诺斯州南部和芝加哥的菲尔德自然历史博物馆。该设施将增加这些机构中广泛的研究人员及其学生之间的合作。 ***
